I was ordering for an elderly friend who doesn't do the internet. Because it is a prescription item, I needed assistance in making the order from my account, but having his vet know the prescription was in his name. It took a couple of calls, but that was fine because I needed help that the initial agent couldn't perform. She directed me to the right office, and they were able to easily figure out what to do. Thanks for all you do.

I switched food for my dog and Chewy did not carry it at the time...so I bought it locally which was fine but having it delivered to my door on a schedule was a nice luxury I lived without for a while. But Chewys added what I needed so I'm happy.

Cowboy has struggled with UTIs and Kidney stones. No matter what dog food I gave him he would get both. After speaking to my Vet they prescribed Cowboy this and we haven’t had anymore UTIs and Kidney stones. Now after fixing him and his age he’s gotten on the thicker side, so the vet prescribed us this to help mange his weight along with preventing UTIs and Kidney stones! 10/10

This is the first time my senior Rottie has been on a prescription diet. I thought it would be a challenge with getting the food then getting him to eat it. Chewy solved the first challenge and he seems to love the new food. 2 for 2!!!
