Keeps my pet healthy and she loves the taste
My 3 babies think they're getting a treat!
I've been giving this product to my pups her entire life. I am away from home without access to my wonderful vet - thank you for being there so we can keep our Little Girl health & going strong!
recommended by my dogs vet. works well.
It is very easy for my dog to eat and be healthy
My dog enjoys the taste and so far so good... hard to tell with things like this, but no adverse reactions or anything. Really great price too!
This is the heartworm medication that our rescue Goldendoodle was on when we picked him up. We decided to keep him on the same heartworm prevention product and the price from Allivet couldn't be beat!
I have used Allivet's autoship for my boys' Heartworm and Flea & Tick for a couple of years. Allivet is great to work with. They are nothing, but helpful and autoship is awesome! I was in a pickle and needed heartworm meds for our new puppy quickly as I didn't know she needed to be on them already. I had some frustrations with my vet and needed to get the med in her system right away since I was already behind. The gal I spoke with was sooooo nice and understanding. She got one pill sent out to me immediately and even waived the shipping for me. We now have 3 dogs and so they will have our business for many years. I am very appreciative of the kind and quick service the Allivet gal gave me!!
I love shopping here you have the greatest deals out there for my 2 pups and your delivery process is awesome..Thank you For yr great service...and it’s great that you had a awesome deal on my heat worm pills cause my husband and I are on disability and it makes it so much easier for us to pay the great prices you have..🐾💙🐾😊
Get the best price and great service.
Great product I definitely recommend. I see no reason to pay extra money just for a brand name. My boy had heartworms when he was rescued at 1yo. He's almost 5 & has been on Iverhart Plus almost the whole time (vet talked me into trying something diff). He likes this & I like everything it covers with affordable price. His heartworm & other test comeback perfect, plus no side effects...so that's why we love it.
Easy to order, even when a new prescription is required. THE BEST prices.
I feel confident when I order from Allivet that I get the real thing and not a fake product.
Good protection; works well!
Works great for my pit! ;-)
Great price
Easy ordering and reasonable price
Very competitive pricing, quick response in delivery.
Our boarder collie tolerates this hrt wormer without seizures
Very affordable for a first time dog parent!
Bought this a long time ago, due to circumstance right now, I had to purchase from another company. Allivet had the best price out there.
My dog eats poop!
I have used this product and have never had an issue. The cost savings is incredable
Price
So far so good
I want to make sure I give my dog the best care possible so, I decided to order from your site
Very good price comparing with other companies!
Keeps my dog healthy.
Is really good to protect the heart of my pitty.
Inexpensive and effective
heartworm for my pet . good product
I find Alli st to be very helpful and knowledgeable. They always help with everything including take care my baby Noelle.
I recently purchased a heartworm medication for my dog. It was simple and they even called me to see if I wanted to order more than just the one dose I ordered. They contacted my vet for verification and then sent it straight to me a couple days later. It was fast and hassle free. I’ll be using Allivet again.
Cheaper than heartgard but same medicine
LOVE ORDERING FROM ALLIVET, PRICES ARE REASONABLE
I have chosen to use this brand of heartworm prevention due to the cost, I have been using iverheart religiously for years and have always had negative heartworm tests.
So much cheaper ordering from here than getting it from the vet, plus they will auto ship so you don't forget

Trusted product
good price
so far all experience with allivet are great!
Fast and easy, delivered every 3 months.
I love that Iverheart contains the same medication as one of the bigger brand names for half the price. With the size of my dogs this option is so much more affordable.
I love that they deliver this right to my doorstep. I don’t own a car nor do I have reliable transportation to get to my vet appointments so this is such a big convenience to me. Thank you Allivet!
Easy reordering.
great value
Excellent customer service and the best price! Looking forward to buy again.
Iverhart Plus has protected both Sebastian [now] and Venice [before him] for years. It is both economical and effective. I am well pleased.
works well with my dog
very good product have reorderd again.....
Great service
Very satisfied
Good source for Iverhart.
Only type of HW control that works for my dogs IBD/allergies since it is not beef flavored like Heartgard Plus.
Doing business with them is a pleasure
Allivet has the lowest price and best customer service
Reasonably priced.
