appreciate the ability to purchase pet meds with the assistance of our Vet talking with Chewy.com
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.
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 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.
My vet no longer carries this. It is so good that I can get from Chewy.
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.
My dog has been on this for the past several years. She doesn’t have any trouble eating it or keeping it down.
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
This heartworm is cheaper here at chewy than my vet and it keeps my dog safe
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.
