A gradual transition to a new pet food is important to avoid digestive upset. To transition, mix your pet’s current food with the new food. Over 7 days, gradually decrease the amount of the current pet food while increasing the amount of new pet food. In some cases, your veterinarian may recommend no transition or a shorter transition time.

Helps with dogs that have sensitive skin
By Dogmaniac on May 7, 2020
My vet prescribed this for my light colored pit bull that has sensitive skin. It really has helped. Between this food and a medicated bath I give him once a week, he is much better. I have used Chewy for years but I had only recently switched him to this food and bought it through my vets office. I had been waiting almost a month for the other place and it never shipped, they had said 7-10 days longer per order, but a month had lapsed. So I sign into my Chewy account and food was delivered in 5 days. I was thrilled with this time because the prescription had to be verified through my dog’s veterinarian. Now I have it on auto ship with Chewy.

On the Fence
By TracyHW on May 17, 2020
Our vet recommended this dog food for our terriers with allergies. We were buying Merrick (also vet recommended) before we switched. The issues we have with it so far: (1) the taste isn't causing them to beat a path to the bowl, (2) it's terribly hard to chew so they're eating less as a result, and (3) it's very expensive. We get that it's prescription dog food, but yikes. It's too early to tell whether their allergy issues are resolved, but fingers crossed!

Tastes good and is good for the skin
By smh1011 on May 1, 2020
I started this prescription food in trying to figure out a hair loss problem with my pit bull Leia. She loves the taste (even more than the hypoallergenic food that she had been eating), and her coat is soft and silky. The bald spots haven't cleared up completely, but that may take much longer than the 2 weeks that she has been on the food. One caveat: this food must be saltier than her hypoallergenic diet ... she always tanks up on water after eating.

Not effective
By Gary on Jan 29, 2020
This didn't work for my dog probably because it is pretty much identical to many dog foods you can buy without a prescription and for much less. Independent testing has show that prescription dog foods contain about the same amount of impurities as regular ones.

This is helping my dog so much - nothing else has even came close
By Weezy on Dec 17, 2019 Top 50 Contributor
My dog loves this food, but it is helping her allergies when nothing else has. She has stopped digging her front feet finally and seems to feel better. I gave a four star instead of five because the price is RIDICULOUS!! I know its great food that helps dogs, but the price range is way too much. There are lots of people who could not afford this and that is not really fair to their pet.

Healthy Eating
By Josie on Sep 4, 2019
I did not realize the damage I was doing to my dog by feeding him any dog food. He is a bishon frise and he is highly allergic to so many things . My vet recommended this food which is a little pricey but really worth it to me. He has been on it for two weeks and he has lost a few pounds,which is good .(he is overweight). I see a difference in his skin and fur.
