Value without a doubt!
I have used PetCareRX for a couple of years now through an employer benefit program. Monthly cost is minimal compared to what I save on both pet food and routine pet meds. Customer service is great as well, they have always taken care of any issues I have with no delays. I would recommend PetCareRX to all my family and friends with pets. by on 11/14/2020
I like shopping at PetCareRx!
I think Iverhart Plus works just a s well as the more expensive brands. by on 08/12/2020
Inverhart Plus
This product has been very effective at keeping my dogs free from heart worms. I mix it with their food and they take it easily, although they will not take it by mouth without being hidden in peanut butter or other food. by on 01/15/2020

Great product for a fair price
We have used Everhart for all of our dogs for many years. All of them take the pill like a treat! Very happy with this product.. by on 03/29/2019
Very Happy
I did a lot of research on the safest and best heartworm medicine which lead me to Iverhart Plus. No complains from me or the consumer :) My 95lb Rottie takes it with no complaints or rejections. by on 03/17/2019
Great product
We've been giving this to our dog for the past few years. Once a month and she thinks it's a treat. by on 08/08/2018
Better Option Than Bigger Brand
I have been using the Iverhart Plus for years. It's just as effective as the name brand stuff and has the same active ingredient. Not sure why you'd spend the extra money for a fancy box and a different chew size. by on 04/18/2018
Very Good! So far so good.
The purpose of this medication is to prevent heartworms. It is hard to rate effectiveness unless it doesn't work. It is very easy to use and the reason I started using it is because the product I used to use was not available at that time and I had to choose an equivalent. I have never changed back.- by on 07/11/2016
Iverhart tabs are value & quality
Purchased a year's worth of Iverhart heartworm max tabs for two small dogs. The price is certainly worth value of the quality- works as effectively compared to the higher priced name brands. Have purchased this brand for previous (3) years, first time purchasing from PetCareRx, and very pleased with service and product. by on 03/04/2016

being using this product for years. Never had any worm of any type. Going keep on using this product. by on 02/23/2016
very good product.
I wish the tablets were smaller or softer so the dogs could eat or swallow them easier. I have to grind them up and disguise them in food so they will get the dosage. I have 2 smaller dogs that have very small throats, and they take the same tables, but in the smaller dosage. There is no way I can get them to swallow the tablets whole. by on 08/15/2015
Good product
Had to buy this brand because normal generic brand was on back ordered. Cost more than other brands but works fine. My dog had no problems with it and took it like I was offering her a treat. by on 08/04/2015
Generic for Heartgard Plus
I will only know if product is effective when I get my dog tested for heartworms at her annual checkup. I am assuming it is as effective as the brand name by on 07/22/2015
Time to deliver
This would have been a great purchase. My vet was playing games to get me to buy from him. by on 06/06/2015
Iverheart
Seems to do the job. When I bought it with PetPlus I paid half of what they wanted on other sites. by on 05/25/2015
this product gives good results for the price
All three of my dogs have been on this mediation for a number of years, I have no problems with heart worms or other parasite. Good results for the price. by on 04/28/2015
Generic Heartgard
This is supposed to be a generic form of Heartgard. I take generic medications because they are cheaper than name brand, so I figured why not give generics to my dogs. If they are good for me they should be good for my dogs right? They are much cheaper than the name brand. My Vet approved them so they must be alright. Now a days you have to watch your pennies. So with that in mind I can still help my dogs while being able to purchase the same medications for them cheaper. I would recommend them definitely. by on 03/24/2015

Iverhart Plus works well for dogs.
Iverhart Plus works as well as Heartgard Plus and it costs less. My dog thinks she is getting a treat once a month. by on 10/21/2014
Big hugs and sloppy kisses
Always so easy ordering. Love the email updates and especially happy with their quick response to me that they received my mailed prescription. I always worry that it may get lost (have had this happen with other online retailers).My dogs really respond to Iverhart Plus and the price is so affordable at PetCareRx. Always price compare and they win out every time! Couldn't be happier with the product and PetCareRx.com My pups give Iverhart Plus AND your website big hugs and sloppy kisses! by on 10/02/2014
Frustrated
My dog has used Iverhart for a few years now. I decided to buy online to save money. Trouble is it's out of stock. Come on folks. It can't be that hard to keep one of your best selling meds in stock. by on 04/12/2013
My dog gets regular check-ups- so far so good....
I have a cockerpoo who loved to eat the chewable type. She wasn't thrilled about taking the pill. She is older and on another medication that is a tablet and didn't like taking that either. I put her daily pill in with her dry food and add a little water..this works great. I just add the Iverhart to her food the same way and there isn't any problem... by on 03/01/2013
Good product
My two years old baby had this product already 2 years and his heartworm test have no problem at all. Good products with affordable price. by on 09/22/2012
Gracie's Mom loves Iverhart
My dog chews these small pills just like she did the name brand cubes. We have used Iverhart now for 2 years and have saved money while protecting our beautiful dog!!!! by on 07/19/2012
easey way to swallow pil
all u have to do to get a dog to take his meds, is to wrap it in a piece of meat and give it to him. i use luncheon meat and i make sure it is well hidden before he sees it. never fails and i have 2 dogs! works great on both by on 06/22/2011
Harder to get a finicky dog to eat
I have 2 poodle - miniature and teacup. The mini takes the pill great whereas the teacup has always fought and I have to make something for dinner that night that I can take a bit of and then crush the pill and mix it up together. She didn't give me any problem with the Hartguard, but it was so much more expensive. It's just a bit more of a pain, but works as well. by on 06/06/2011
Great product- as good as the Name brand :)
I have used this for a couple years and my little boy loves it. I recommend it to anyone looking to save and get a quality heart worm pill. PS Don't blame the product when your dog gets sick... (side effects are listed) next time ask your vet before using a new product :) by on 05/10/2011
Saves me a ton of $
I purchased this with a 15% off coupon, my dogs loved it, and I saved about 60$ over buying a 12 month supply of heartgard from our vet for each dog. by on 02/14/2011
Easy way to give Iverhart to a finicky dog
Crush the pill into fine powder and mix with some soft food. The dog doesn't know the difference and you do not have to struggle with the dog to take it. Love the price of this product! by on 06/17/2010
I will not be using this again!
My dog vomited all night after taking this medicine. I have a 3 lb. Yorkie and I gave her the smallest dose available, which is for dogs up to 25 lbs. I don't understand how a 3 lb. dog should have the same amount of medicine as a 25 lb. dog! My vet recommended we try cutting one in half for her next time, I couldn't stand to see her that sick again. I am now looking into topical choices for heartworm prevention. by on 06/01/2010

Virbac easy to give
This product works great and is a great price. I just get my dogs all excited by saying "Want a cookie" and jumping all around. They just swallow it and have no idea it was meds. Then they smile. by on 06/05/2009
Protects but dogs don't like
I'm sure this pill protects just like Heartguard but my dogs didn't like it even though it's flavored. It is a small like a pill where the Heartguard is more like a soft beefy nugget & they think they're getting a treat instead of medicine. I had to force this pill down both our dog's throats & I don't like doing that so I am going back to Heartguard. by on 04/16/2009
My dog doesn't like the taste
My dog has been on heartworm prevention all his life. He is now 11 years old. Living in Florida, it is a must to be able to prevent heartworm. However, my little Stinker, a Shih Tzu, is starting to fight me, despite covering the pill in peanut butter. In December was the worst. He ate around the peanut butter (loves this stuff) and spit out the pill. I had to force him to swallow it. I don't like doing that. by on 01/02/2009
A Welcome Change
Came to the house VERY quickly for standard shipping. I usually use that other well known brand (Heart.....) bought from the vet, but the price was really getting outrageous for 6 tabs. Thought I would try the Iverhart on a recommendation - sure glad I did! Gretchie gobbled it up just like the old "candy" and I saved a few kopecs in the process. by on 08/02/2008
EASILY TRICKED AND FOOLED
OUR LITTLE DARLING THINKS SHE IS GETTING A TREAT AND THERE IS NO TROUBLE GETTING HER TO SWALLOW THE PILL.ย  THAT SURE MAKES IT EASY TO TAKE CARE OF YOUR BEST FRIEND. by on 07/26/2008
Quick service!
Wow...that was quick!I was hesitant to try buying my pets medications online but, after being WAY overcharged repeatedly, I decided to give it a try. I've ordered twice from PetCareRx; Heartworm medication and, Frontline. I had a bit of a glitch the first time with the prescription but, it was MY fault, not theirs. Once we got it straight, I had my heartworm medication in two days. I ordered the Frontline this past Tuesday afternoon (online); by Thursday afternoon it was sitting on my porch! I am now recommending this site to all my friends! by on 07/12/2008
Great product , easy to administer
Great product . No problem giving the tablets to the dogs. They like the flavouring. The packaging can be a little tricky to open at times but overall great product and value for money. by on 06/21/2008
Like a treat!
I tell our maltese mix Belle that its a treat! She gobbles it right up, great price too! by on 06/13/2008
PROTECT THEM !!!!
THIS IS A GREAT PRODUCT. IT'S VERY EASY TO ADMINISTER AND THEY DON'T MIND THE TASTE OR THE SIZE OF THE PILL, IT'S SMALL. YOU ONLY HAVE TO USE IT ONCE A MONTH AND YOU'LL HAVE NO WORRIES. JUST DON'T WAIT UNTIL THE LAST MINUTE TO ORDER IT. THE COMPANY HAS TO GET PERMISSION FROM YOUR VET BEFORE YOU GET IT SO THIS TAKES A LITTLE TIME. THIS PRODUCT IS SOLD AT AN AWESOME PRICE! THE PROTECTION YOUR PET WILL GET FROM THIS MEDICINE IS A MUST TO KEEP THEM HEALTHY AND HAPPY. by on 06/10/2008
No Heartworm
We have six dogs and live in the mosquito prone South. We have been giving Iverhart Plus to them for years now and it has worked! The pills aren't as chewy as some other brands but they seem to like it just as well. by on 05/03/2008
Love my little Sadie Girl
I would never even think to not give my Sadie (she is a sheltie, ssh don't tell her she thinks she is one of us) Iverhart Plus pill once a month. She is protected and it gives me great peace of mind knowing she is not going to get worms. We live in NC so it is a must for our little girl. I was buying these from my vet but decided to see if I could get them cheaper online and sure enough I did. Sadie loves the taste so it is not like giving her a pil more like a treat. by on 03/24/2008
