Rated 4.5 out of 5 by 44 reviewers.
Rated 5 out of 5by GOT A BIG DOG FAMILY? PERFECT!!!!! I am so thankful for PetCare RX! Recently one of babies was treated for heartworms and may I just say how horrible this DISEASE is!!! The treatment is very PAINFUL and there are no guarantees for full recovery... THANKFULLY my baby survived and is now heartworm free! We have 4 babies and buying this at our Vet is crazy expensive! So, thank you again PetCare RX, I sleep better now. 07/13/2016
Rated 5 out of 5by A great alternative My dog ate this without hesitation. I will be using this product from now on as it is cheaper than others and is effective as a prevention for more than just heart worm. 07/09/2016
Rated 1 out of 5by Not what I was led to think Disappointed thought they were chewable won't order these again said they were the same as brand name 06/14/2016
Rated 5 out of 5by Great productTri Heart Plus is a great affordable product that gives me peace of mind for my 3 cocker spaniels. 05/18/2016
Rated 5 out of 5by Heartgard Plus OffsetThis product has the same active ingredients and levels as Heartgard Plus but at a much lower price. This is a no brainer!!! 05/01/2016
Rated 5 out of 5by very effective, much better value than heartguard pluswe've used this "generic" version of heartguard plus for several years and have not had any problems with heartworms or side effects. 03/08/2016
Rated 5 out of 5by This product is equal to Heartgard but costs much less.Thank you for thinking about the high cost of preventive care medicine for the dogs we love. I have three rescues so it helps when companies consider the prices pet owners have to incur to keep our pets healthy. 03/05/2016
Rated 5 out of 5by Great itemThis is the first heartworm my pet actually will chew up and likes.You were out of our regular product but now like this one better, cheaper also. 02/23/2016
Rated 5 out of 5by Great Heart worm ProductWorks just as well as the name brands but it cost a lot less. Only problem is my dog does not like the flavor of the tablet, I have to coat it in peanut butter before she will eat it. 01/31/2016
Rated 5 out of 5by Easy to administerGetting my dog to take her heartworm medicine has always been a problem, until I started with Tri-Heart Plus. She takes it like a treat and I don't have to disguise it in her food. I am happy! 01/02/2016
Rated 4 out of 5by Good product to protect pet's heart!Overall it was an easy ordering process and shipped fast! I didn't pay attention and assumed these were chewable and not hard tablets. I wish they were chewable as my dogs would take them easier. Otherwise very happy customer! 11/03/2015
Rated 5 out of 5by Easy order and fast deliveryIn past got the same brand at a vet and cost $18.00 more! My little dog of 15 lbs thinks it is a treat! Very happy with ease of ordering! 11/01/2015
