Food sensitivities and intolerance are potentially serious problems that can result in sensitive or irritated skin, coat and ear conditions or even gastrointestinal upset. Dogs that have a food sensitivity or intolerance, also called adverse reactions to food, typically experience an abnormal response to the protein in the food. If your dog suffers from adverse reaction to food, it is even more important to feed the right food. Hill's nutritionists and veterinarians developed Prescription Diet z/d clinical nutrition especially formulated to support your dog's skin and food sensitivities. In fact, z/d is clinically proven nutrition to help avoid adverse reactions to food.

Key Benefits

  • Helps improve digestion and stool quality with highly hydrolyzed protein
  • Helps eliminate food related causes of skin irritation and results in visible improvement to the skin and coat
  • Helps maintain a healthy skin barrier and enriched with essential fatty acid
  • Developed with a single carbohydrate source: Corn Starch
  • Clinically proven antioxidants are added for optimal health benefits

  • I was vomitting and had diahria

    By on

    I was vomitting and had diahria long enough that you could see a significant change in my waistline. A trip to the pediatrician said it was anything from sensitive stomach to cancer. Fortunately for me, my human went with the lesser of evils and purchased this food for me. I LOVE LOVE LOVE it!!! My other food, which was also top shelf, would sit in my bowl all day and I would eat it at my leisure, unless of course my cousin stopped by, then I would wolf it down. But this stuff, MMMMMM, I wake my human up in the morning and then start reminding them early afternoon that I want to eat! Thank you Hill's, I am one happy puppy. Sincerely, Miley

  • Canned prescription dog food for Duke

    By on

    Duke is a twelve year old miniature pincher/cock-a-poo mix. He has eaten Wellness kibble, since he was a puppy. Now, in his senior years, his veterinarian has put him on a strict diet of Hill's prescription diet for skin and food sensitivities. He will be on this for the rest of his life. Thank goodness, he is enjoying both the can and kibble Hill's diet. I am glad I can order it from Chewy and have it delivered to my doorstep in only a day or two.

  • Tummy issues

    By on

    My dog has always had tummy issues and all she could eat was the Hill's Prescription d/d venison food. Since that food is no longer being made, our vet had us try the z/d. And she is doing well. And kudos to Chewy.com for making this is easy to buy. I just sent them a copy of the vet's prescription and the food came right to my doorstep. It couldn't be easier!

  • Food is part of the recovery process

    By on

    My dog has been sick since September, 2016. Actually, probably longer. After visiting the third vet, she was diagnosed with ulcerative colitis.After three months of cooking food for her, she has finally transitioned to the canned food. At this point, she eats well and and is having normal bowel movements. She still has a long way to go, but I am very satisfied with the food.

  • Totally Onboard

    By on

    Love the idea of ordering food for our little dog online. No more running out to buy it or finding it's out of stock and being in a bind when it's a prescription food you can't get just anywhere. This is so convenient, and delivery is amazingly quick. Can't say enough good about Chewy.

  • Good for dog allergies

    My dog has an allergy making her lick her bottom (more often than usual). This food has cured her from this problem. Also she loves the food. We have another dog with no problems and she loves the food also. We also bought the dry food - they love that also.

  • Boxer loves it

    By on

    My boxer loves this food. You would think we were feeding her steak or something like it. She can't wait for dinner. Her mouth starts to water when we reach for the can. It has helped all the allergy and stomach issues she was having.

    Charlie has always had food issues. Sensitive stomach, refusing to eat after a couple of months of whatever food I gave him, very soft stools. My vet suggested this food and he loves it! And his stools are solid now!

  • So far so good!

    By on

    My dogs love this food! Even my picky eaters lick their plates clean! I haven't noticed skin improvement yet, but to be fair it's too early to tell. Of importance is I haven't noticed any skin worsening either.

  • Queso loves it!

    By on

    My French bulldog, Queso enjoys her meals much better now that there's can food added. She has severe food allergies, but when she eats z/d I don't have to worry about her skin breaking out. I would highly recommend this product.
