Hill's Prescription Diet d/d Canine Skin Support Potato & Duck Dry Dog Food is rated 4.8 out of 5 by 26.
Rated 5 out of 5 by from So easy to get now! Our dog has food allergies like you wouldn't believe. Not only does she need prescription diet dog food, it must be duck and potato. In the past we have often been caught out by not ordering soon enough to get the new before the old is all gone. Chewy has solved that.

Rated 5 out of 5 by from This food is great for food allergies My lab has been eating this food for about 2 years. He was diagnosed with food allergies by the Vet. This food has made a huge difference in his overall well being.

Rated 5 out of 5 by from Hill's Prescription Diet I have a very small dog, in the 5 pound category, and the morsels are larger than he would normally want to chew, it is almost painful to watch however he really does seem to enjoy the flavor and has chosen the food over a doggie treat. I would be great if Hill's came out with the same prescription food but in smaller "bite size" pieces

Rated 5 out of 5 by from Life Saver! After 3-1/2 years, we finally found a food that works. This was our last resort before seeing a specialist, which we really couldn't afford. We have tried everything, including raw, dehydrated raw, freeze dried, top of the line kibble, home cooking, etc. We did allergy testing and found out that flax, coconut, sweet potatoes, chicken, beef, salmon, turkey, apples, broccoli and lamb were problems (to name a few). Our poor sweet dog would either have GI upset from the food, or severe itching. Prescription food was our last resort just because of all the bad things that people would say about it. Although the ingredients don't thrill us, it works for our dog. After just a couple weeks, she no longer licks her paws constantly, she is not up all night scratching and no GI issues at all...stools are perfect. We also give a probiotic by Mercola and she is doing great!!

Rated 5 out of 5 by from This product has a flavor my dog loves. When my dog was given this prescription from the vet I thought "he's never going to eat this". My german Shepherd is the pickiest dog around, I usually have to doctor up his food with hamburg or chicken, but not the duck and potato, he actually eats this without anything added. It's like a miracle with Max and we are all shocked!

Rated 5 out of 5 by from Cured my dogs digestive issues This product fixed all of my dogs digestive issues. We had been giving chicken based high quality foods. We kept going to the vet for diarrhea and vomiting. Finally we tried a novel protein limited ingredient diet and it was a miraculous transformation. We have saved so much money by switching to this food.

Rated 4 out of 5 by from For food sensitive dogs. My small dog will eat these kibbles. Almost likes them. But rarely eats them without some wet food or special extra on top.
