  • Heartguard
    Heartguard for dogs- PetCareRx had a great deal! Better than our vet as well as other online pet med sites! Fast shipping too! by on 05/11/2008
  • Good price
    Good price for this product and just what the vet recommended. by on 05/11/2008
  • Like a treat
    My dog readily snatches up the Interceptor like a treat. Great service, great prices....MUCH cheaper than the vet! by on 05/11/2008
    Great product but please get your prescription first. I had to make many calls before I could get my order. The price on line is a big savings. by on 05/10/2008
  • Very pleased!!
    Best price out there and quick to my front door! Thanks!! by on 05/10/2008
  • The Best there is!
    Not much I can say other than five years on Interceptor and my dog has never had heartworms. On top of that, he absolutely loves the taste of it and that's from a dog who spits out non-flavored pills. Easy to give him and works great! by on 05/09/2008
  • Great Value
    My vet recommends interceptor. I have 2 large very healthy dogs. They take the pill with no problem. PetCareRx offers a very cheap and easy way to order prescription drugs. I will definitely buy from again! by on 05/09/2008
  • Great Service
    I have used this product in the past and it requires a prescription from the doctor. I ordered this product because it was cheaper than getting it from the doctor. The presscription was obtained from the doctor for me and I did not have to do a thing. What wonderful service. Thank you. by on 05/04/2008
  • Would recommend this website.
    Ordered Interceptor on this website, and was very happy with the whole transaction. Plus, the price was almost $30 cheaper than what my vet quoted me! by on 05/04/2008
  • Great for your dog's paws, too
    My dogs love the taste of Interceptor as if it were a treat. With three large dogs, it is important to make "medicine time" quick and easy for me. I also had a problem with hookworm sores on my female's paws. She had weeping sores with pus inside and after one round of expensive Cipro, and continued use of Interceptor, she has not suffered this malady again. That's a cost savings and peace of mind. With its protection from mosquitos, I no longer see my dogs scratching for what seemed like hours at a time -- all summer long. We have a lot of rain in the spring and the mosquitos are everywhere, so it's a big plus. I recommend this product to those pet owners that live in the country, as this is a multi-purpose, once-a-month, highly effective medication. The only side effect one of my dogs experiences is wanting a lot of water the first two days after I give her the chewable medication. by on 05/04/2008
  • Inceptor
    I have been giving my shih tzu Inceptor for many years. I give it to him year round for heartworm disease caused by Dirofilaria immitis, the control of adult Ancylostoma caninum (hookworm), and the removal and control of adult Toxocara canis and Toxascaris leonina (roundworms) and Trichuris vulpis (whipworm) infections. Petey always gets perfect annual checkups at the vet and he is eleven years old. Keeping your dog in excellent health will help him live a long and happy lifetime. I would not for a moment even consider leaving Petey go without heartworm and intestinal worm protection for even a month. I live in Florida and the warm weather year round insures the survival of mosqitoes and intestional parasites. I will not do without it. by on 05/03/2008
  • Best on the Market!
    I have been using Interceptor on my shih tzus (2) for years, It couldn't be easier. Another plus, it's cheaper on the internet than at the Vet's office. Never a problem getting them to take the medicine!!! by on 05/03/2008
  • Heartworm protection
    Seems like a good product. Heartworms can be a life threatening problem. I'm afraid of drugs but this one seems to keep the heart worms at bay. by on 05/02/2008
  • Awesome
    I have always used interceptor for my dogs. Although I lost my 13 year old poodle from old age, my two jack russells (one is 5 and the other just turned one) I have always had my dogs protected from killer worms (they have always tested negative.) I have always purchased from my vet but wanted to try you folks out and was very pleased with the service and quick delivery. You will see my orders from now on for interceptor and other products. Keep up the great work. by on 04/28/2008
  • Great Product!
    I love interceptor. All 4 of my dogs are on it, and they look forward to their monthly "treat". Been using it for years. PetCareRx has the best prices I've found. by on 04/26/2008
  • heartworm medicine
    good price, good service. helpful as I am old, Thanks a lot. by on 04/26/2008
  • Great Price
    5 years ago, I rescued a Yellow Lab from the shelter, the next day would have been too late for him. I never got the story how this sweet dog ended up in the pound, but he had been abused. I'm so glad I decided to take a look at the shelter that day. When I took him to my Vet, he already had heartworms. So, he went through treatment and has been taking his pill every month and is doing great. This was my first time to buy his medicine online, I couldn't believe how much cheaper it was from what I was paying at the Vet's office. When his Advantage runs out, I know where I will buy it. by on 04/24/2008
  • Great Value-Great Product
    We have 2 very large dogs (130+lbs each), so medication can get very expensive. By purchasing a year supply of Interceptor from PetCareRx for both dogs, instead of at our local vet, we saved over $60.00. Our order was shipped out promptly, and we are very satisfied with the product. by on 04/22/2008

  • Highly Effective Heartworm Prevention
    Have been using this product on our pets for years without any problems. We like that it protects from other worms including whipworms that can cause colitis problems. by on 04/21/2008
  • works great
    my cocker spaniel had a reaction to her previous heart worm medication so we switched to this brand and she hasn't had any problems. it works great! by on 04/19/2008
  • My dogs are happy campers without heartworm!
    I have 7 little chihuahuas so it's a bit of a problem sorting out the tiny tablets to the right mouths, but I put them in cheese. Just wish the packing was easier to open to get the tablets out. All my kids just love it, especially the chesse, I'm sure. Great prices too! by on 04/19/2008
  • Same Thing
    This product is highly recommened and is the exact same thing you would get from your vet. Just at the vet you would pay much more. It was at my house in no time. If you are rich(have no problems with gas shooting through the roof) get it from your vet, otherwise get from PetCareRx. by on 04/19/2008
  • Returning Customer...for a reason!
    Love the ease of ordering, free shipping and special discounts. Prompt shipping! by on 04/15/2008
  • Like the protection, hate the tablet!
    At the recommendation of my vet, I switched to Interceptor from the Heartgard because it protects against an additional worm. For this, I will continue to use the product. However, my dog LOVES the chewy Heartgard formulation and HATES the Interceptor tablet. We have to mask it in a hunk of cheese, which I don't like giving my dog. I wish the Interceptor had the consitency of a treat rather than that of a hard vitamin-like tablet. by on 04/02/2008
  • No problems with Interceptor
    My dog has been on Interceptor for 5 years, with no side effects, and he has consistently received negative test results for heartworm. I'd say it is working just great! by on 03/28/2008
  • Charlie is healthy
    We have been using this product for our dogs for years. We have been very pleased with the product and they have had no side-effects by on 03/25/2008
  • "Major", "Heidi" and Toby and Lacey
    "Major" and "Heidi" have passed on to the big doggie heaven in the sky, and Toby and Lacey are taking Inceptor. All four of our dogs have taken Inceptor with no disguises. They take it as if it were a treat. Inceptor does what it is supposed to do and the dogs love it. by on 03/16/2008

  • Intercepter - Green
    I have been using this product for 4 years now. I have tried other heartworm medications, but my fussy Shih Tzu would not take them. He loves his small Intercepter pill, and quickly eats it every month. He sometimes even sits up and "begs" for it! by on 03/13/2008

    I have no problem getting our rottweiler to take her interceptor, and since she was a puppy and started her on this treatment she has been worm free! by on 01/20/2008
  • Excellent!
    Been using this for 6 years and my dog has never gotten heartworm disease! by on 12/07/2007
  • Great Protection
    When our dogs got whipworm last year, we found this to be the only product to protect against it!! Plus it covers heartworm! Saves a lot of money to buy it all in one convenient pill! We're users for life! =-) by on 09/28/2007
  • Execellent
    It treats not only heartworm but ticks and mosquitos.I don't dislike anything except if it were less costly. by on 09/16/2007

  • Lifesaving product
    I tried this product when one of my pups got hookworms. I have used it faithfully since then. by on 06/22/2007
  • Heartworm Tablets
    This product seems to be working very well. My pet is on this medication for about 1.5 years and she is tested negative for heartworms and doing great. Only thing I would like to see in addition is the affordable tablets with protection against flea and tick so that I don't have to apply frontline or similar protection. by on 05/23/2007
  • Interceptor for heartworm and other parasitic worm control
    Easy to give and always provides a negative test result. by on 05/06/2007
  • Peace of Mind
    We live in an area that becomes rampant with mosquitos, it gives us great peace of mind that our little girl is protected. The vet just gave her a good going over and she is very healthy. Thanks for the great price. I recommend this product whole-heartly... by on 04/28/2007
  • Big Healthy Puppy!
    Each time Maggie May goes to the vet, he's thrilled with how healthy she is! No worms... ever! Dr. Smith recommended Interceptor and I used to purchase it from him, but it's much cheaper on here. by on 04/10/2007
  • Best for Heartworms
    I have used Interceptor for years and never had a problem with heartworms, and we live in mosquito alley. Interceptor comes with a guarantee and hopefully I will never have to use it. by on 03/12/2007
  • A great product, from a current 4 legged weiner dog!
    Had a great flavor, & no trouble getting that one down. by on 03/11/2007
  • JJ Loves
    Our border collie is so good about taking her monthly medicines. All we do is set them on the floor, and she cobbles them up! by on 03/05/2007
  • Better than heartgua
    I've been using this medication since my dogs were pups. The older male started out on heartguard however he breeder said that heartguard would not protect against whipworm. The vet wanted me to continue using heartguard. I will continue to use interceptor. I also have to disguise the pill in some tasty treat to get them to take it. Sometimes the male dog gets wise and tries to spit it out. It's still worth it! by on 01/21/2007
  • kills worms too
    I switched to interceptor because my rotti got whipworms while on heartgard. (they get it from other dogs *walks in park) my vet then told me that interceptor protected him from those & heartgard didnot. I have to hide it in a tasty snack to give it to my dogs, but it's worth it for the protection. glad I switched. by on 09/01/2006
  • Fewer seizures
    I have a cocker who seemed to routinely have seizures within 24 hours after I gave him another brand of heartworm medication. I tried Interceptor on Spencer and saw a dramatic reduction in seizures. Not sure it is coincidental or not but Spencer is much happier on Interceptor.*This is a prescription item by on 04/07/2005
