Makes My Beagles Sick

Every time I give this to my two beagles, they spit it out. I end up adding a treat to each piece and feeding them the pieces they drop one at a time. One beagle ends up with stomach issues and loose stool. Both of them are a bit more clingy and act a bit off on the day they get this medicine. I will be switching immediately.

Recommended by my vet, and affordable

Aside from the fact that these are Vet recommended and affordable, my dog will actually eat them without protest, and without slathering them in peanut butter. All-in-all, a good deal all around.

Great Product

I have been using this product for my dog for a number of years. It is easy for her to take (I hide it in a glob of peanut butter) and I can be confident she is protected for a month. This is a great product and I recommend it.

This is a great product. Shipping with Chewy's was fast and I love the fact that I could order in single dose as my puppy will grow fast.

This is by far my favorite heartworm prevention. Dogs gobble them up like treats. Take care of other nasty internal worms.
