About This Item


For use in animals only. Your furry friend must have a current heartworm test result on file with your veterinarian in order to be prescribed heartworm medication. Please visit your veterinarian to have this test performed annually to protect your four-legged friend. Help protect your pet from pesky pests with Iverhart Max Chews. These soft chews are formulated to help prevent heartworm disease and can also help treat and control the other three most common worms—roundworms, hookworms and tapeworms. This broad-spectrum medication helps to provide safe and effective year-round protection when given monthly and is intended for dogs 8 weeks or older weighing 25.1 to 50 pounds. To top it all off, it has a drool-worthy bacon flavor that your dog will love.

Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.

Chews were very hard

I have a good sized puppy who eats everything. She didn't mind the flavor but the tablet was rock hard but described as "chewy". She broken it into pieces and kept biting them (not chewing). I had to crush them in her food. She usually eats everything in her bowl. She left lots of this hard bits in the bottom from the tablet. Good delivery and communication but the item is hard.

Great Experience

Chewy made it easy to get my prescription heart worm preventative meds for my dog easy. They checked in with Bella's vet for me, no paperwork, no mess. They filled her prescription!

Hard Chew, Not Soft

Hard as a rock. I got a box from my vet and my pup just ate it; then ordered them on Chewy. It is a struggle to get my dog who eats everything to eat this. I wrapped it in cheese, covered it in peanut butter, placed the hard crumbs in ice cream and finally in a slice of ham. This was for one chew! Don't waste your money.

Iverhart Max

My vet no longer carries this. It is so good that I can get from Chewy.

Amazing price

This came highly recommended by our vet. Waylon tolerated the medication well. The price was amazing for a 6 month supply compared to our vets office.

Good product

My dog has been on this for the past several years. She doesn’t have any trouble eating it or keeping it down.

Hard chews?

I ordered these from Chewy after getting the first dose from the vet. These are ROCK HARD and they are meant to be soft chews. There does not appear to be any compromise to the packaging. They are in fact in date, not expired. I am very displeased with the product I received from Chewy.com

Iverhart Heartworm

This heartworm is cheaper here at chewy than my vet and it keeps my dog safe

my two aussies do fine

Does exactly what it’s supposed to. For those that don’t eat I just break it in half, slather peanut butter on it and my dog has no issue taking it. Or hide it in cream cheese.
