On Day 5 and Day 6, mix 25% of the current diet with 75% of the new diet. On Day 7, you can feed your pet the new food exclusively. Ask your Veterinarian about the best way to transition your pet to a new food.

Dog loves it!
By OtisMom on Nov 27, 2020
Due to healing from gastric bleed our vet recommended Hill's Science Diet Rx food however we are diehard ProPlan due to quality and no history of recalls so we elected to go with this food. Excellent choice, she loves it and the other dogs try to steal the bits that hit the floor. Best of all her healing has rapidly improved, she is now playing and chasing squirrels which she hasn't done in months and months.

Great prescription for my diabetic dog
By KathyO on Oct 30, 2020
My vet prescribed Purina Dry EN for my girl (Bichon-Silky mix) after she was diagnosed with diabetes. I don't remember why and had something to do with absorption, but I had her on a different prescription diet before and she hated it. Not this. She absolutely loves it. I mix just a tiny bit of Purina EN canned and she cleans her bowl every time. It is important that she eats regularly since she receives insulin twice a day and I don't have to worry about her turning up her nose at this. The vet said my other dog who is non-diabetic can eat this too and he is even pickier and he loves this food. I do not mind paying more if this is a healthier option for our girl.

A small price to pay considering the high cost of her insulin and test strips. It is a joy to see her enjoy mealtime as much as she does. To be blunt, the one side effect I noticed is that she poops a LOT more, but she has never had GI issues; just poops a lot. … more

Best I’ve found for dog with sensitive stomach
By Rogo on Nov 6, 2020
This is the only kibble that reliably produces firm stools from our Great Dane. Harley clearly prefers it over a dozen other products we’ve tried. We added a few spoons of canned EN to each meal. He liked to lick the spoon :-) We purchased direct from our vet until we went on the road full-time in our RV. Chewy quickly reached out to our vet for a prescription and shipped our order. Great service!

Great food

My GS had diarrhea and it has stopped vomiting and the diarrhea. We are planning to due blood work to R/O EPI. My vet wants him on this food for several weeks. Expensive but better than diarrhea.

Great food for a picky & sensitive stomach dog
By Annie on Oct 27, 2020
My 3 year old golden retriever has had an extremely sensitive stomach since he was a pup. We tried a few other different foods that he seemed to either not tolerate or not like (picky). I’m so relieved that this food is easy on his stomach and he actually likes it! Would recommend!
