First chewable heartworm medication they would actually take without putting it in something.

I recently purchased this for my two giant breed dogs and couldn't be happier. My dogs thought the chews were delicious and they had no digestive issues at all. This was my first experience with Entirely Pets Pharmacy and I will definitely use them again. They had the best price (by far!) and handled contacting my vet for the Rx and shipped to me very quickly. I also love that they kept me informed of every step of the process via emails.
ProsDogs loved them, Easy ordering, Fast processing
