“I have been using Sentinal for over 20 years its a hartworm & free control that works and I trust. Allivet always has the best prices on this product and it is quick and easy to do buisness with them.”
“I bought this product for my new puppy. I read up on the different products like this one, and this was the one with the least side effects...When I discussed the product with my vet, he was supportive of me buying this medication for my puppy, which I trust his opinion more than anything. So far so good with this medication, no side effects, and she is doing well.....thanks”
