I’ve used this for my dogs for years. It works great against worms, ticks and fleas. No side effects that I have observed. Will continue to order.
by Brandie on 07/30/2021
Excellent works great!
by Nancy Westrick on 07/22/2021
This product is the only one we have ever used for our dogs!
by JT on 07/13/2021
We have used Sentinel for our Jack Russells for over 25 years. We have found this is the safest form of heart worm and flea/tick for this breed. We have had no side effects that our Veterinarians could find on labs and check ups.
by Freddi on 02/12/2021
Great deal and works
by Brandon on 11/16/2020
I keep coming back because I can't find a better price elsewhere.
by Deb Webb on 10/19/2020
I tried Sentinel to save a little money and will be switching back to Trifexis. Sentinel seemed to work fine at first, but the last couple of doses have still resulted in fleas on my pup. Never had that issue with Trifexis, even in the summer months.
by Megan P. on 08/25/2020
This is a great product for fleas and ticks and heat worm...
by Jim85254 on 08/20/2020
Great Product and keeps vets safe from ticks and heart worm...
by Kuzmaj85254 on 07/28/2020
Works great, no side effects .

Excellent product - quick delivery.

Fast efficient delivery and price!
by Robert Stout on 06/02/2020
I've been using Sentinel for years. This product works well and there don't seem to be side effects
by Brandie on 04/10/2020
Much better pricing than at the vet's office and the customer service is great.
by Linda on 03/01/2020
I have been using this for years it is a good product.
by kuzmaj855254 on 11/22/2019
its good stuff!
by Linda Kidd on 11/13/2019
Sentenial keeps my home flea free, and that is a must!
by Pixiemom on 10/28/2019
Love everything about your site! Have been a customer now for two years!!
by S. Bourg on 10/03/2019
I have 5 of my dogs on Sentinel, so far so good!!! I find it a good value, now it does not kill tapeworms, however keep fleas off your dogs then it's not a problem...I use Frontline Plus in conjunction with the Sentinel.
by Paula on 09/03/2019
I have been using Sentinel for my dogs for as long as I can remember, 14 years for my current dog and around 11 years for my previous dog; and I trust it COMPLETELY. Never had any issue with heart worm and it seems to take care of intestinal worms that my dog gets sometimes when he drinks water from the stream where we walk. Never would consider switching to another brand
by Theresa Liu on 08/22/2019
Ordered sentinel for our lab, they handled everything with the vet and it shipped quickly.
by Chris on 06/16/2019
I have been using Sentinel for my two small dogs for years, always heartworm free at their yearly test. The tablets are small,so they are easily hidden inside a treat. Never have a problem getting the medication down my two picky pooches. Another thing I really appreciate about Sentinel is that it also protects against fleas. Never have had an issue with fleas, no additional products needed. PetCareRX has the best price, and fast shipping!
by Teresa on 05/28/2019
Our vet recommended instead of topical. Both our dogs eat tabs without any issues, eating it with their dog food ust like it's another tasty morsel. And it certainly is effective.
by Sandy on 05/15/2019
The Sentinel price was the lowest I've ever seen and the product is excellent soother is really nothing else to be said.
by T-Mack on 04/11/2019
Not easy to give. Have to use pill cover and that increases price.
by mphillips on 04/05/2019
I have three dogs and the price is VERY REASONABLE
by Mary Anne Hepner on 04/04/2019
My 3 Year old Yellow Lab doesn’t have any issues eating these. She thinks they’re a treat lol.
by Hugo Barrera on 03/02/2019
The representatives at Pet Care RX ,com were thoughtful and timeley with this order. The order was correct, and shipped promptly. I will recommend this site to all.
Thank you so much.
by Richard Crouse on 03/02/2019
Great price and quick shipping
by Karen Graf on 02/25/2019
We use this for both of our dogs, and have had no issues with fleas. It's a better option for us economically, and we like buying 12 months at a time.
by Fletcher's Mom on 02/05/2019
I use Sentinel because it show safe for pregnant and nursing mothers. I find it very effective for flees. I have never found flees to be a problem, even with 4 golden retrievers.
by Randall Stowe on 01/19/2019
She thinks that she is a treat while taking this medicine. She says she wants more of this.
by Chiaki on 01/09/2019
One pill does all great to use and dogs love it.
by Amanda on 12/29/2018
use them. otherwise you will have a house of fleas...
by Dog Mom on 11/06/2018
I had been using Trifexis on all of my dogs. For the past few months, I've been using Sentinel instead, since Trifexis is just not in my budget.
While I can't tell a difference on my two black dogs, my white dog has been having visible fleas all the time. Since Sentinel only kills flea's eggs and not adult fleas, we started having a flea issue in the house for the first time, since we've had these dogs. We live a warm state with long, warm summers and fall, so I'm thinking Sentinel isn't going to cut it for us.
by IK on 10/09/2018
My pupper finds this pill easiest to eat, and does not throw it up later like others we have tried.
by Jake Williams on 08/27/2018
I take my dog to the dog beach and dog parks so he is exposed to many parasites but he remains parasite free. Sentinel works great!
by Randy on 08/11/2018
my dog takes this without difficulty. easy to give and very effective!
by leah on 08/08/2018
You have to presume it will work.
by Mary on 07/17/2018
I've been using Comfortis and Trifexis for years and never had an issue. I decided to save a few dollars by switching to Sentinel, since it was compared to Trifexis...worst mistake ever. Seems like the fleas are attracted to my dog even more. I will never buy this stuff again. Will be switching back to what I know works. Comfortis or Trifexis.
by Ayana on 07/03/2018
I have been using Sentinel for years for my pugs and have not had any problems with fleas. Two years ago I switched to Seresto flea collar that was suppose to work for 8 months and within 5 months all my dogs had fleas. I have switched back to Sentinel and also use Frontline Plus during the summer months.
by Gail S on 06/08/2018
Purchased my heartworm meds for my 5 Chihuahuas from PetCare RX. The service is perfect for me. Easy order, they contact my vet for approval, great communications regarding status of my orders. Love that I can pay with Paypal! Will continue to use this petmed pharmacy!
Thank you PetCareRX!!
by Carla P. on 05/26/2018
so far works well for my dog, no fleas or ticks despite walking and running in wooded areas.
by jose on 05/14/2018
Nothing bad to say about this product. Ive been using it since my boys were puppies.
by Amy on 05/10/2018
I have been using Sentinel for two years , Its effective and Max doesn't mind it. I break it in half and he chews the tablet. I used to have a terrible time with Trifexis for my previous pup, a German Shepherd . Horrible taste and smell.
by Judy on 05/08/2018
Sentinal is great for flea and heart worm protection. My dog has been on this for over a year now, and just had vet visit and negative for heart worm. this medicine has proven it works, no fleas ever.
by Diana on 04/20/2018
I like 2 in 1..Heartworm and Fleas
by Karen Dannenberger on 03/28/2018
We have used this for years for our dog. She likes the chewable tablet and it has been very effective.
by Kernersville Pet Owner on 03/25/2018
...for all our dogs going back decades!
by Dennis on 02/22/2018
So nice with long hair dogs (4 of them) to do an oral pill for everything vs topical. Easy to remember to give once a month. No fleas in our house with them all on the meds.
by Sarah J on 01/31/2018
So far so good. Been using this for years. This is much more tolerable for Dog's with heart-worm, etc. med. sensitivity's which my Dog has.
by Laura on 12/20/2017
We've been using Sentinel for our dog, Boone, for the aspt four years and it works well. Boone eats it without a problem. All annual heartworm tests have been negative so the product works.
by catladyx10 on 07/02/2016
Great for your Pet and I thank Petcarerx for the great customer service every time I do an order!
by Sophie8 on 07/01/2016
we've used this product for many years, very satified. GREAT price.
by Cath on 07/01/2016
We have been using Sentinel for a few years now and PetRx saved us quite a bit this year. This keeps our dogs healthy and heartworm free and is incredibly convenient to order online with renewal with the PetPlus program.
My dogs eat this like a treat - no bread or peanut butter or anything like that needed. They have been flea-free their whole lives so I don't know if that is our yard being well kept or if it is due to the Sentinel. Same for heartworm - this monthly treatment appears to have kept them healthy. They have no side effects whatsoever when taking this product.
This product - even though some think it takes care of Ticks, it does not. If you want tick prevention, you have to get another product. Our veterinarian also explained that it does not kill adult fleas, it only kills flea eggs and prevents them growing on the dog in the fur, so if you have outdoor pets or they run in unmowed fields, etc, you might want something that keeps the adult fleas off of them as well. But for us, this is all we need.
PetRx delivered this to us fast and with no hassles. Thanks!
by LMerchant on 06/23/2016
We are very happy with this product. Been using Sentinel for many years for our dog.
by Betty7 on 06/10/2016
I don't think this product had enough ingredients to keep fleas from attacking my two dogs. We fed them the products per the directions. We've since requested and are still waiting to receive a dose of Capstar to see if that can improve their condition.
by Mary5903 on 05/26/2016
When we bought our home we discovered that a previous owner had lost a dog due to Heartworm. We sure do not want to repeat that loss...so have to be diligent about a preventative. Sentinel is perfect for that and PetCare had by far the best price!
by bonbon711 on 05/26/2016
Great product as it combines flea and heartworm into one pill. However, my dog does not like these and I have to give it to her with some peanut butter. This has not been an issue with other pills.
by Clintymae on 05/02/2016
the prices are excellent and the product works great!
by Angie21 on 03/28/2016
I have been using this product for about 3 years. He is 9 years old and is running around like a puppy. Love this product!
by Anthony on 02/05/2016
I would not recommend this to anyone who thinks their dog might come into contact with fleas. This product does nothing to fend against adult fleas so you will have to invest in other products to treat them. It is cheaper for now a very apparent reason...
by EmilyS on 01/25/2016
I got everything I was promised price delivery 100% what I wanted great company thank you so much
by Satisfied100 on 12/25/2015
Loves this because it also has a flea repellent so in fall/winter we can skip the Frontline with no worries of any fleas!
by JLoveMosca on 12/22/2015
You communicated with the vet to get the prescription, sent the prescription quickly, and made the whole transaction very easy. I enjoy working with you.
by Aspen on 12/16/2015
I have been giving this to my dogs for about 3 years. Every time the heartworm test comes due, the veterinarian has yet to find any critters in my dogs blood. It is doing exactly what I would hope it would do.
by Buckeye on 11/23/2015
We were using Comfortis but a friend recommended Sentinel instead. When we learned that Sentinel was cheaper than Comfortis, we were interested. But the fact that it not only took care of fleas & ticks but also worms, we were sold. We have not had one flea since beginning the treatment!
by Keri on 11/08/2015
I have been giving all three of my dogs Sentinel for years. It is an affordable, convenient & effective product. I highly recommend it.
by MikeHawk on 11/06/2015
The company was fine. They contacted my vet, process was easy. The bad part is now I'm getting email daily....annoying. when I want to buy more, I'll let you know.
by Ozziesmom on 10/19/2015
This is an excellent product and the only one that does not upset my dogs stomach, give it a try you will not be disapointed. Ask your vet!
by minkie on 10/17/2015
just started sentinel to early to tell effectiveness.Everything else about transaction was excellent
by jrjr on 09/26/2015
We are happy with the Sentinel product. We used to use another brand, without good results. Sentinel works for our dog?
by Nellie on 09/17/2015
I have always liked this product. It works well and is easy to use. And the dog likes it!
by mamapitbull on 08/10/2015
I have been using this product for many years and have always been happy with it.
by Kathy3 on 07/25/2015
Easy to dispense to your pet. Double flea and tick protection when given with food, when also using a flea and tick med. highly recommend this product.
by Luvdoggies on 07/06/2015
So glad to have Sentinel back on the market. It has been a long time waiting. Our oldest dog who is 10 was on it since his birth. All of our past dogs and present it seems this is the only easy pill to give and works wonders with no problems. No side affects and no worries. We started using this pill back while we lived in NJ and now in Texas.
by RitaLee on 07/04/2015
this pill works. It significantly helped my yorkie not get bitten from all the bugs in Florida, where we live. He never scratches air bites his skin anymore. Changed our lives.Highly recommended.
by Lisab on 06/10/2015
We have 4 scotties-the sentinel is well tolerated! No side effects---which we had with another well known comparable product
by Barry on 06/08/2015
I have used Sentinel on every dog I have owned and never have had a flea or heartworm problem. I have used this product for over 10 years and absolutely love it!!! One pill a month and you are done!
by Checkers on 05/22/2015
I purchased this product for simplicity and ease of use. My dog likes the tablet and it covers all kinds of parasites I want to protect my pet against.
by Monisa on 04/23/2015
I like that you can purchase the same medication from Pet Care Rx that you can get from your vey but at a cheaper price!
by KW77 on 04/10/2015
First of all I have to say to those giving a low rating because you can't get your dog to eat it put it in some food. We are rating the effectiveness not how well you can handle your dog! This stuff is great I saved so much money on buying flea prevention separately. My white dog always had an ugly grease mark from the topical and she likes to swim so it never worked for long now just an easy pill that anyone with a brain can administer and we are good to go!
by Colliemom15 on 04/09/2015
My dog takes this little pill very easy and eagerly. Works well for fleas. Wish it worked for tick's too but have to buy something else for that.
by pix10 on 03/23/2015
product not received from pet rx, the product works great for the past year
by Dukey on 03/07/2015
I have been using Sentinel for my two dogs for six years now. There is a huge problem with Heartworm in Texas and although my dogs mostly stay inside, there is no skimping on the protection that I give them. They are my babies and thus, Sentinel is given to protect them from Heartworm, fleas, and other parasites. I give one to each once a month on the same day and I do not need to worry for the remainder of the month about whether or not they are safe.
by Sus1953 on 02/20/2015
very good for my dog service is always great mailing is good I have no complaints at all
by casper10 on 02/18/2015
I wish this would kill the fleas that may already be on the animal. I had to use a topical just in case they had fleas already. I do like the combination heartworm, flea, and other worm prevention. You just need to make sure the animal DOES NOT have fleas as it will not kill the ones already on the dog!
by Sbayly on 01/16/2015
Two weeks ago was the first time we gave to our dog, Mandi. Mandi spit that sucker right out and we knew it was fight time... we put it in her mouth again and she seemed to be eating it but she was faking us out. Then we broke into pieces and wrapped them in some ham slices...she ate the ham but found the Sentinel. So then, we did what any good parents would do... I held her and my husband shoved whatever was left down her little throat. I can't wait until next month.As for effectiveness, she doesn't have fleas so I guess it works.
by carolc720 on 12/20/2014
I used to pay $150 mo for my pets flea and heartworm. Until i found PetCareRx. Now i pay less than half that. Shipping takes a little bit so i recommend ordering early to keep in the cycle. Other than that, I'll never buy their meds anywhere else.
by teddy6139 on 12/08/2014
easy to administer and keeps my dogs flea free for a month at a time. works on my big 'outside' dogs and my little buddies. We live near the beach and fleas are a nightmare with the warm humidity and sand. playing in the water makes the topical flea control useless.
by MikeyOne on 12/01/2014
Good product, good price, delivery was on time, thanks
by sam1234 on 11/20/2014
I would recommend this product. It's easy to use and very convenient.
by Kristie on 11/06/2014
Well, my dog has been given these all his life and the vet couldn't get them anymore, I don't remember why.I just place the tablet in a spoon of peanut butter, easy dosing because there is nothing my dog likes better than peanut butter.
by Laura1065 on 11/04/2014
I found the tablets hard to give to my dog. I thought flavor tab would mean it would be flavorful to dog. but no, I finally crushed tablet and bought wet food and mixed it in the wet food for dog to get it. Not sure if crushing it was ok. Also, dog is still scratching, from fleas? I don't know. so not sure if the flea part works good.
by swatt on 10/28/2014
We have used Sentinal for several dogs over several years, and we've always been pleased with it. The current dog takes it buried in peanut butter and gobbles it down.
by Micky on 10/16/2014
our dog hated the liquid drops to control fleas and ticks. he takes this like its food no worries about fleas or ticks and does not run away for monthly dose. dog how runs to you to take dose because of the good taste.
by kobi on 10/09/2014
One pill. Once a month. It's that easy. No liquids. No mess.
by Ffrh911 on 10/08/2014
I choose to use this product for my dogs, because it doesn't make them sick or itch. The last heart worm medicine I used would make them sick and scratch like crazy. This one does not do that.
by Shanb2167 on 09/15/2014
So far my dogs have not had any fleas. I believe this product works good. My service and price was very good from PetCareRx.com.
by kcarter001 on 07/28/2014
Much cheaper than heartguard and also protects against whipworms.
by kellylu on 07/23/2014
Dogs love it so it easy to give them their "treats" for heartworm & other parasite prevention.
by Jnichols52 on 07/11/2014
Sentinel is easy to use. My dog eats quite readily. I use it because it controls both worms and fleas. The price is reasonable compared to other combined worm and flea products. It does not kill fleas, it only prevents the eggs from hatching. I use another product to kill the fleas.
by Laceygirl on 06/23/2014
Heartworm preventative is an expensive part of pet ownership. I shopped around and got the best price from PetCareRx.
by sbrsmmns on 06/22/2014
I used this for years and then my vet changed the dogs to Trifexis. My dogs hated it! They spit it out 2 and 3 times, and I mean from way down their throats!! There has never been an issue with the Sentinel, they will even eat it out of my hand if I forget to put it in their bowl with the food. It has been effective for heartworm and fleas for all of our dogs.
by sabehanv on 06/19/2014
My vet prescribed this for my dogs a couple of years ago. Since I have been buying these from PetCareRx, my savings have been substantial over what the vet charged.
by patriciamatuschak on 06/06/2014
finally I can give my 2 small dogs 1 pill a month that covers heart worms and the fleas etc. Trying to find the spot between their shoulder blades for the fleas etc. meds has been awful. They're happy campers and so is Mom :-) Thanks a lot!
by lostNdoghouse on 05/15/2014
Geez people do some reading. Sentinel doesn't prevent flea or tick infestations. It interrupts the flea life cycle by preventing the development of flea eggs. Adult fleas and ticks will still get on your dog. Sentinel is primarily a heartworm, hookworm, roundworm, and whipworm preventative. It is also the safest heartworm med for the herding breeds that may have MDR1 gene mutation issues.
by Sammy91104 on 05/11/2014
I have two dogs. We gave them this medication three weeks ago. While taking them for a walk, we get home and they have two fleas on them? My puppy has thicker fur and tends to attract the fleas more then the other one. Not only was it hard to give her the tablet, she kept spitting it out so we have to use a pill pocket, but it did not work. I paid all this money for yet another unsatisfied product!
by Linzee0124 on 05/06/2014
I used Sentinel from the start when I got my Shep-Colli-Lab mix 8 yrs ago and had no problems at all. Then they put the hold on the manufacturer for another product and I was forced to switch to another product which was way more costly and did not keep the fleas at bay. I had to first take care of the flea problem that then developed in my house (another expense) and then switch to another product. I was thrilled to see they started selling it again. Great value, easy to use and it works!Radio
by RadioMom on 05/04/2014
This product was not available for some reason. I used Trifexas in the meantime - it is wonderful that it is back since it quite a bit cheaper and the dogs take it well - in fact my collie takes it better (the Sentinel).
by birder on 04/22/2014
very effective, less money than other brands, dog tolerates the medication well, dog heartworm test negative. difficult to find a heartworm chewable for dogs under ten lbs. This med works for both of our dogs.
by tillou on 04/14/2014
I have only given her the 1st dose, we live in Florida, the flea part of has not worked well yet, hopefully the 2nd dose works better. It would not be fair to say it does not work, not yet!
by Bella15 on 03/31/2014
Our vet introduced us to this product and we like how it attacks two things in one pill and you give it once a month. One less medicine to keep up with.
by SpeakChinese on 03/23/2014
My little Chihuahua will not eat Heartguard even chopped to teeny pieces & mixed with chicken! I guess she smells it.So the only way to get her heart worm medicine is with Sentinel. I crush the tablet into granuales & add it to her dinner.For some reason my vet doesn't stock it any longer so I have to now buy it online, no problem, arrived within a week.
by LaLaChihuahua on 03/22/2014
I have been using this heartworm preventative for a long time. I have never had a dog with heartworms and felt okay with not testing regularly - it didn't seem necessary- my dogs always are in peak condition.
by Suzzyq on 03/14/2014
Gives great protection from fleas....ticks.....heartworms...and several other pests. Dogs like the taste and you can give it as a treat or put it in their food . It is a little pricey....but less than some of the combined meds. Buying them separate is more expensive.
by Jeanie on 03/05/2014
I have two dogs who play at public parks, the levee and swim in the Mississippi river. Sentinel is excellent for preventing heart worm and controlling or eliminating any problems with fleas. I couldn't be happier with this product.
by riverdog2 on 02/21/2014
Easy to use and my dog takes it readily. You only give it once a month. This is what my vet wants us to use.
by LarryB1942 on 01/21/2014
This product is simple and gets job done. I am glad that it came back. Thank you
by RosaR on 01/02/2014
I have used sentinel for years and now using pet care rx I have the convenience of home delivery at a great price.
by Gina11 on 12/29/2013
At first - the dog that I am babysitting spit out the tablet, then I placed it more deeply into a piece of chicken, and viola'. The scratching and biting stopped the next afternoon.Thank you Sentinel.
by Adoptivemomonly4moment on 12/26/2013
Great price on a highly recommended dog heartworm med.
by scooterpie on 12/22/2013
I feel this is one the best all in one flea and heartworm medications out on the market.
by dschmidt74 on 12/12/2013
I bought this product because it stated that it is for the, "prevention and control of flea populations, the prevention of heartworm disease and the treatment and control of roundworms, hookworms, and whipworms in dogs." Turns out it didn't do a thing for fleas!!! My black lab is allergic to fleas and this product did nothing for her. When I took her to my vet, they told me that Sentinel doesn't actually prevent fleas, as the product review would have you to believe. So I now have 5 months worth of an expensive heartworm treatment, seeing as how I'm going to have to purchase an additional treatment for fleas. Will never buy this again and Molly will be back on Trifexis as soon as a months time is up!!!
by jaj0926 on 12/10/2013
I just started using it and for right now it seems to be as good as what I got from my vet before.
by Lacy1234 on 12/05/2013
I was pleased by the quick, attentive service of PetCareRx. I haven't had time yet to evaluate the product but based on previous orders with my vet the product is also good.
by Leighbert on 12/02/2013
I would recommend Sentinal highly for your dog especially because of the price from PetCareRx.
by randy on 10/29/2013
We have given Sentinel to our cocker spaniels since they were puppies. They have never had any problems taking it and it's very convenient to order online.
by 2Spaniels on 10/28/2013
My Freddy love it. I love that he only have to take one pill a month.
by Noemi on 10/22/2013
My vet does not handle Sentinel and since it has worked so well in the past, I got a prescription for my two dogs andthe order was received within five days.
by sheltiebordercollie1each on 10/19/2013
My dog ate this without any problem. He didn't like his previous heartworm med. I've only given it to him once, and it did seem to upset his stomach, even though it was given with a meal.
by SPAC on 10/17/2013
Very polite and professional. Super fast ddelivery time.
by babe on 10/05/2013
Puppy took this pill on 9-1-2013..Tonight in the car the puppy coughed up a tiny worm,,,,I'm trying to figure out what kind of worm it could be...
by inkeaau on 09/23/2013
i have been using for many years, great product. heard a rumor wasn't available glad to see still here.
by mill43 on 09/10/2013
Great product. It also keeps fleas and ticks away!
by rudedog on 09/05/2013
So far so good. This is the first month we've used it. We had been on Iverhart Max but had adverse reactions and had to switch. No reactions thus far, thankfully

No stomach upset, just feed with your pets food. So far no fleas or ticks. Like that I don't need messy flea drops on my dogs coat each month. Money saver as well.

So glad its back. The only all in one product that actually works!!

Part of the reason I got this product was to get rid of the fleas on the dogs. Despite dipping them with a Permethrin Dip, they are still chewing and scratching on themselves?The instructions say that this product will inhibit the eggs only and not kill the adult fleas. To be perfectly fair about this, the instructions said in order to complete the treatment, I would have to add CapStar Tabs to their diet once a week and treat the yard for fleas, carpeting, and bedding areas.So, I have ordered CapStar Tabs and Bifen Granules. Once I get all this, then I will systematically give them CapStar, treat yard, powder carpet, and wash bedding. Then hopefully, this will kill the darn fleas off completely! I am SO Tired of this!Since I am not sure of the outcome yet, consider this review incomplete on the outcome of this product. The reason I am listing a review is because they keep sending me all these emails asking for one.

I liked that it was a combined flea & wormer And that there was not a oil residue on the coat. My collie had experienced some intestinal problems prior to use; that is cleared up now!! Easier to use than the skin application products, they ate it in their food without hesitation.
by wildfire on 07/22/2013
I hated the oily topical products and was glad when I found Sentinel Flavor Tabs. I have only used it one month but everything went fine and only one product to purchase instead of two.
by sew1246 on 07/21/2013
I bought this product instead of Triflexis as it does the same thing but costs about half the price! We are only one dose in and dealing with a major flea infestation right now so cannot say YET how truly effective it is. Fingers crossed because the price and double-duty of this pill make it a winner...

Great service..prompt order processing and delivery.
by Debb on 07/19/2013
I have used this product for years and I live in the south with a lot of fleas. I have not had one flea problem in the house. I like this product over all the others on the market. My dogs health has been and still is perfect. I will continue to use and recommend others to use this product.
by batleh on 07/18/2013
This month is the first time I gave my dog Sentinel. He took iteasily and I saw no adverse effects. I have seen no fleas on him, so I am pleased.
by Lucky8 on 07/15/2013
They had a big selection, great prices and fast delivery!
by Luv2ski on 07/15/2013
This product is great. For my dog: no upset stomach, no refusal to eat it and it has been effective against heart worm.
by Myboysam on 07/11/2013
I used this for 12 years on my last dog. Now that I have I new puppy I am vary Happy I can get this product for him. This is the best price I have found.
by Bonny on 07/10/2013
My dogs had fleas really bad in may so since then I've been using sentinal and for over a month they have been flea free! I have 3dogs 2 dachshunds and a Great Dane and it worked on them all
by Hfusco on 07/09/2013
Good service just slowed waiting for vet. Sentinel is good for fleas and heartworms.
by jenbato on 07/08/2013
This is the only heartworm protection that both of my dogs can take without it coming back up. I love the fact it covers more than just heartworms. I have given this to all my 4 legged babies. Best buy for the money I highly recommend this product!!!!! :)
by MyGirlz on 07/03/2013
So excited this product is available again. All others made our boys sick and were too big to swallow (as they did not want to chew them).
by JakaRoo on 06/28/2013
I have one dog that will eat anything, and the other who will eat around pills - no matter what I put them in! Sentinel is like a treat to him!! He eats it right up! They never got sick from it. They don't have any problems with fleas or anything like that. Definitely recommend!
by Anonymous Pet Parent on 01/27/2012
We switched to Sentinal a few years ago after getting skin reaction to the topical preparations. With three Goldens, A Mom and two litter mates, we have had no problems except the price is exorbitant, twice that of a similar crewable, Hartguard.
by poodle_runner on 08/21/2011
I highly recommend this product. I give it to my two Shelties, ages three and two and a half, and neither one of them has ever had a single flea. I live in Florida where fleas are a year round problem.
by Walda_owner_of_two_Shelties on 08/18/2011
I highly recommend this product. I have two Shelties, one is almost three years old, and the other is two and a half years old. Have never had a flea on either one of them, and I live in Florida, where fleas are a problem year round.

I am very pleased with Sentinel and completely trust this product. I used Comfortis for approximately 5 months and both of my dogs had seizures once a month for the 5 months that I gave them the medication. It was awful. After repeated trips to the vet and numerous tests we finally figured out the Comfortis was causing the seizures. I wasn't aware seizures are a possible side affect from that medication. I also tried Frontline and it seemed to really irritate my min pins skin when I applied it so I immediately stopped that. I haven't seen any side affects in either dog from the Sentinel and I have been using it for the past year. I have not seen fleas on either dog either. I'm not sure if certain medications affect certain breeds however I found it odd that both of my dogs suffered seizures approximately one week after the administration of each dose of Comfortis.
by poodle_runner on 07/14/2011
Love love love Sentinel! Have used it on my Rat Terrier for almost 2 years now and have never had any issues. The convenience of one product for both heartworms and fleas is fantastic!
by Anonymous Pet Parent on 07/12/2011
I had always used the liquid flea treatment for years on my dogs. The last two dogs I had, toy poodles BOTH developed cancerous tumors. The male used to scratch at the spot where I would put the liquid and it would get red and irritated for a few hours. He was 11 years old and she was almost 15.She tolerated the medicine better, but it still got her in the end. I totally believe its what gave them both cancer. One of the liver the other one his stomach cavity. I have 2 new dogs. They have been on Sentinal for 2 years as of Aug. I have had no problem and I like the fact that it protects for all the parasites and the fleas so I only have to give one pill to each of them once a month. I have not seen one flea on either dog. I highly recommend this product.
by Jnet_owner_of_Phoebe_Labradoodle_and_Jake_Mini on 07/10/2011
I can not recommend this product. I gave it to my Choclate Lab at my vets recommendation. The first tab she took she became lethargic , could not eat within the day. She could not get up. Very hard to find ANY information as to the testing done. Got a refund. I went back to Heartguard and Frontline. I have used them for many years on several breeds with no issue.
by Pat_dog_lady on 06/21/2011
I have a beagle and three jack Russells. WE Have used this product for over 5Years. I see an occassinal flea but never had a problem. Would not even try any thing else.
by poodle_runner on 05/23/2011
True, Miss South Carolina, this product does not kill fleas. Fleas live just a short time (a week or so) and reproduce prolifically. This product prevents a flea colony from gaining or maintaining foothold in your home. We have three Jack Russells in a flea-infested, pet-friendly island community and have seen zero fleas on them in the past four years. The flea population where we live has apparently developed an immunity to Frontline as it has little or no effect here. Sentinel took about six weeks to begin showing effect but since then, it has been the complete and total cure we had hoped for. Best thing we have ever used, but it took some patience.
by poodle_runner on 04/22/2011
Used for 2 dogs large and small breed and had excellent results. I had next door neighbor who had regular flea infestations and my dogs never had an issue...not even visual fleas...even tho my vet does not carry it, in fact it's hard to find a vet who will carry it (contracts with competitors) but I rave about it and despite some vet critics, I highly recommend it
by poodle_runner on 01/01/2011
Do I need a prescription when ordering Sentinal for my dog? I know the strength she needs as I have bought it from the vet before.
by poodle_runner on 12/12/2010
Charlie was our first pet in Florida, a Llahsa Apsa. He lived to be 18yrs. we gave him Sentinel tablets for at least 10 years. It was the best. Today we have a rescue dog, lab & beagle mix. His name is Harry & does not like the topical products so we put him on Sentinel, he thinks they are treats. No mess and no fuss.

We have given Sentinel to our pets for the past 25 years. We have never had to worry about our girls using this product. We have had the pleasure of living with six loving girls in the past and now with two new toy poodles. This is a wonderful product!!!!!
by poodle_runner on 05/13/2010
I love this. My dogs will eat it no problem and so much easier than messing around with topical solutions. On large dogs the topical meds are hard to apply, you have to spread it over the whole body and it is hard to judge how much to apply to each area, I always have some left over because I am afraid I won't have enough at the end. Also it is difficult to part the hair on very short haired dogs. I made sure the dogs were flea free with Advantage and then started this pill, haven't seen a flea since..it won't kill adult fleas so it is best to get them off first. LOVE PetCareRx paw points and coupons...saving a lot of money, PLUS their prices are the lowest to begin with !!!!
by Big_dog_lover on 04/19/2010
Purchasers should be aware that this product will NOT kill the fleas you see on your dog. It sterilizes the fleas and prevents them from reproducing. If you are looking for something that will kill the fleas you see on your dog, you should get Frontline Plus for Dogs. After my vet explained this to me, and online reasearch easily backs it up, I quit using this product since it won't do what I need.
by Anonymous Pet Parent on 12/02/2009
I have three dogs and have been using this product for over a year. I just found fleas on one - she has white hair so it was easy to see them crawling around. I am considering switching back to Heartgaurd and just using a topical flea medication now.
by poodle_runner on 08/21/2009
My dogs are on Sentinel now and Program the year before. Prior to discovering this medication, I tried every available spray, powder and spot treatment without luck. The fleas in South Tampa, Florida can reproduce amazingly fast and nothing worked - until I used Program. Because of it, I switched to Sentinel for the heartworm protection instead of using separate drugs. Both of my dogs love the flavortabs and consider them "treats". It's always good when the dog likes it, right?
by poodle_runner on 08/03/2009
I've used this product for 2 years now and I love that I do not have to worry about fleas and paracites on my dog. I have never had any issues with my dog bringing any "buddies" from the outside!
by Tamara_Owner_of_LoLo_MastiffPit_mix on 06/04/2009
I have had my American Eskimo Spitz all of his life (14 years) and have had him on Sentinel tabs from the beginning. It is really a good product and does exactly what it says it will. He has never had one flea, to my knowledge. And of course no sign of heartworm, through all of his testings. Receiving this medication through PetCareRx is faster, cheaper and very reliable. The coupons are a great bonus!!
by Anonymous Pet Parent on 04/22/2009
My two dogs are 7 and 8 and have been on Sentinel since birth except for about a years timespan when the vet switched them to Heartgard and Frontline plus because they had had a few tics and the Sentinel isn't for tics.Big mistake! During that time we had a flea infestation. We switched back to the Sentinel and haven't had fleas since. The only problem I have with Sentinel is that one dog loves it and will chew it right out of my hand. The other one avoids it after sniffing it and I have to crush it and put it in some other food that kills the smell for her to eat it. AND, ordering through PetCareRx is easy and less expensive than at the Vet. Keep the coupons coming!
by RC on 09/02/2008
The people at Pet Care Rx showed that they care about service. I received very personal care and the products I ordered, arrived in record time. The products are exactly as I have purchased at the Vet, but half of the cost. I am very happy, and my four legged friends are happy and healthy...and that is the reason I will only order from Pet Care Rx
by Kat_owned_by_two_Pembroke_Welsh_Corgies on 08/16/2008
We have a Sheltie which has a lot of hair! Our vet uses this product on his dogs. We have never had a problem with fleas since using Sentinel ( 10 years ) . To save some money , it would be good to send the product in a padded mailer vs a big cardboad box! I love all the coupons. We saved quite a bit of money and received free shipping!
by Beth_owner_of_a_Sheltie_3_cats_and_3_gold_fish on 08/16/2008
PetCareRx has superior customer service and very quick delivery. It is cheaper than buying at the vets. Will visit again!
by 12_lb_Maltese_owner on 07/07/2008
I have had my two yorkies on Sentinel for years and it is the best heatworm/flea control medication I have ever used. One pill does the trick instead of using two separate medications which can result in higher costs. The pill is very tiny making it so easy for even the smallest dog to swallow.
by Barb_yorkie_owner on 06/21/2008
My two dogs have been on this medicine for about 7 years now without a SINGLE problem. Keeps them flea and heartworm free. I was quoted $80 from my vet for a 6 month supply. With a discount coupon, I just paid $101 including shipping for a 12 month supply! A huge savings! Service was great, they contacted my vet for me and shipped it in a few days. I've previously considered 1-800 Pet Meds, but the prices were never worth it compared to my vet. PetCareRx has changed all that. This is where I'll buy my pet meds from now on.
by Mike_silky_terrierpekingnese_owner on 06/15/2008
Over the past 15 years we have rescued dozens of speical needs greyhounds and others. We alway depend on Sentinel to keep the dogs and our home environment healthy. I do not know how many hours we spent combing and bathing before this product was introduced. Especilly for former racing greyhounds who are exposed to many tick born diseases and given no prophylactic care. It is exceptional to be able to protect these good animals from so many potential parasites with an easy once a month pill.
by greyhoundx on 06/07/2008
I've purchased Sentinal for my Yorkshire Terriers for years but this is the first time I've used PetCareRx. I placed my order on Monday and received my shipment on Friday....and this included PetCareRx contacting my vet for a prescription. PetCareRx is fast...!
by Sue_owner_of_two_Yorkies on 06/06/2008
Our Maltese Poodle Diva has been on this product since she was a puppy. She has a luxating patella and the Synovi has helped her stay active and without pain for almost 6 years now. It is a super product!
by Divas_Mom_Melinda on 05/17/2008
Sentinel is the only medicine that I buy for my Dogs. I think it is the best heart worm medicine that you can buy because it also controls fleas & worms. PetCareRx is where I buy everything. They offer a great price & fast shipping.
by Jim_Miniature_Pinscher_Chihuahua_Jack_Russell on 05/10/2008
PetCare RX has a large variety of flea and tick medications.I've used Sentinel before. I like the combined treatment and onece a month dose.We have not seen nor had problems with fleas in over 2 yrs. My dog's last heart worm check up had a clean bill of health.I Found Sentinel to be a few dollors less here, than at my vet. My shipment arrived fast and was packaged securely . My pet's name, vet's name and instructions were on the box.
by Linda_a_mixed_breed_owner_ on 04/19/2008
I was very pleased with the fast service and shipping. I received my order within four days of of ording. It was flawless. I will definitely order again.
by Joan_English_Cocker_owner on 04/19/2008
I use Sentinel for all 4 of my dogs and it is great. Besides keeping fleas from breeding, I love that it prevents heartworms.
by Madeline_a_dalmatian_owner on 04/16/2008
I have always used Sentinal for my dog. It works very well for fleas - haven't ever seen a single one, even on the indoor cats and I don't use a preventative on them. This might not be the case for areas that are high flea areas, but it's the case for us. I like purchasing it from PetCareRx because they are a few dollars cheaper than the vets and they deliver to my door!
by Tina_Pet_Lover on 04/04/2008
I highly recommend getting your pet's need from PetCare.The price is within my budget. They ship it quickly.The product is as good or better then what you get from you vet.
by Jan_has_5_loving_dogs_My_babies on 04/03/2008
We have used this product with our Boxer for two years since we got her and she has never had a flea. I love this product and so does she. She eats it like a treat. I have her do a trick first so she knows it is a reward not a medication.
by Anonymous Pet Parent on 04/02/2008
Have a mini-dachshund and have had no problems using this medication. Great that it is a 2 in 1 pill (flea & heartworm).
by Doxie_Mom on 03/25/2008
We've used this product for our older dog, now gone and now for our puppy. It is great and we've not had any problems with it so far.

My dog bullet gets great check ups at the vet. No worms, and No fleas or ticks. We live in an area with trees and water. He does not mind eating the tablet but he is finiky. A dab of peanut butter does the trick.

I rescue special needs greyhounds and small breeds. This is the only way to be safe and sure that they are paricite free.
by Anonymous Pet Parent on 11/29/2007
Our vet recommended this product because it prevents numerous parasites. Our dog just eats the pill from my hand with no fuss. He loves it and thinks it's a treat.

this is the only product i would use on mydogs, it is safe and it works
by Linda__2_yorkie_owner on 09/08/2007
We give this product to both our babies and they are well protected, which gives us satisfaction knowing they are growing up safely covered by the bad things that could hurt them...
by Maureen_husky_Nakoma_sheperd_Mika on 09/03/2007
This stuff works great, all issues that can affect my dogs are taken care of in this one pill. Our puppy got a few fleas on him at the groomers and within 24 hours they were dead. Love this stuff!

I have been using this product since it first came out. I have always had a multi-dog family of as many as 5 dogs at a time and currently live with 3 dogs. I have never had a problem with fleas and the additional parasite medication is an added bonus to this product.

by Curt_past_owner_of_a_chowchow_and_now_a_black_La on 07/02/2007
The Sentinal Product is the combination of two very effective products, Program for fleas and ticks and Interceptor for Heartworm. I have used Program for 15 years on several dogs, and it eliminates fleas. My dogs live outside 100% of the time in Florida, and they do not have fleas. Zero! There is nothing like it on the market. It steralizes fles so they cannot reproduce, and effectively eliminates fleas. They never come back once eliminiated. By buying Sentinal, you save money over buying both a heartworm and Flea/Tick protector separately.I would not use any other product.
by Yellow_Lab_and_Catahoula_Leopard_Owner on 05/02/2007
I use to work at a vet clinic, we highly recommended this product. I love the heartworm prevention and flea prevention all in one.
by Anonymous Pet Parent on 05/02/2007
I really like that it protects against not only the different types of worms, but also fleas and ticks. It truly does work and my dogs take it without us having to conceal it in cheese.
by Kathy_owner_of_two_Shitzus on 04/17/2007
I would not trust anything else as we live in the country and love our big Labradoodle puppy. What makes it special is that it keeps the fleas off and prevents heartworm and hookworm. We feel very comfortable that our best friend is protected.
by Rich_Arlea_Labradoodle_owner on 04/02/2007
I like the ease of the product. One pill for heartworm and flea control one time and month. Investigate. It's worth it.

I have a Pembroke Corgi that is now 9 mos. old. He has taken Flavor Tabs for 6 mos. and has done very well. I put a little peanut butter on the pill and feed it to him with my finger. I really like the idea of not using flea soap or a flea collar on him because my grand kids play with him a lot.
