Pets can be sensitive to sudden changes in their diets. For this reason, it is extremely important to follow a gradual transition plan to best support your pet's health and product effectiveness. It is recommended to follow at least a 7-day transition plan before exclusively feeding your pet a new food. Start by mixing 75% of your pet's current diet with 25% of the new diet on Day 1 and Day 2. On Day 3 and Day 4, mix 50% of the current diet with 50% of the new diet. 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.

| Days 3-4 | 50% | 50% |

HILLS SCIENCE DERM DEFENSE
By Colbey on Feb 15, 2021
We are trying a new food for our dog b/c of licking his paws. We have tried many Rxs and nothing seems to help. It is too early to tell if this food will make a difference so I gave the item a 3-star rating. Thank you for being so kind and generous during this time of trial and error. Blessings!

Excellent for environmental allergies
By Foritchydogseverywhere on Jul 15, 2020
My white American Bulldog developed allergies when we moved to a new city. She began scratching and chewing herself raw. Working at a veterinary hospital we started her on [expensive] allergy meds, but after a few months they stopped helping, so we sought out the help of a veterinary dermatologist who performed some skin tests and determined she is allergic to a dozen things in the environment from fleas to pollen and certain trees. This is the only food that keeps her from scratching and chewing her skin raw since it is made specifically for dogs with environmental allergies. This is not meant for dogs with allergies related to food, so chances are, if this food isn't helping your dog, their My white American Bulldog developed allergies when we moved to a new city.

Helps with dogs that have sensitive skin
By Jole 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.
