Adverse reaction to food.

Food sensitivites 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 sensitivities 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.

At Hill's, nutritionists and veterinarians have developed clinical nutrition especially formulated to help manage your dog's dietary sensitivity and help reduce the possibility of adverse reactions to food.

Feeding Guide

Daily Feeding Guide:

Important Feeding Information

  • These amounts are a starting point only. Your dog may need less or more food to maintain proper weight. Adjust as needed. If you are unsure, ask your veterinarian.
  • With your veterinarian's approval, mix increasing amounts of your dog's new food with decreasing amounts of the old food over a 7-day period.
  • Prescription Diet formulas are available in a wide variety of dry foods and treats for your dog's unique needs, and canned foods with delicious flavors your dog will love. Supplementation with other foods or treats is unnecessary and may decrease the effectiveness of the food. When using with canned food and treats, decrease the amount of dry food to avoid overfeeding.
  • Keep fresh water available at all times!
  • For best results, have your veterinarian monitor your dog's condition.
  • To prevent suffocation, keep this package out of the reach of pets and children.

Wonderful for allergies This product has really helped my dog with his allergy problems. He did not like it at first but has taken to it. October 30, 2013
This product has helped with my dogs food allergies. My dog has extremely bad allergies (food & inhalant). He went thru 2 different types of prescription diets before he was put on his current Hills Prescription food. The other 2 foods, my little guy kept throwing up. He hasn't had any illness from this food and this food has def. improved his allergies, skin and coat. Before starting this food, my dog would have outbreaks of hives and patches of itchy spots which would turn into open sores. His amount of outbreaks from food allergies has drastically decreased and looks a lot healthier. May 28, 2014
Top of the line! As a veterinary professional, I understand how crucial it is to feed your pet the appropriate diet. Seeing clients day in and day out who insist on feeding "organic, grain-free, raw, etc" diets drives me crazy because I see the damage it does to their beloved pets. This food is great for food allergy dogs (and no it is not the same as over the counter "allergy" diets because the machines are cleaned and sanitized for hours before production begins ensuring no cross contamination plus the protein is hydrolyzed). My "allergic to everything" mutt has always been itchy because she suffers from food and environmental allergies. Even D/D was making her itch, though not Z/D! It's phenomenal. I absolutely love, trust, and stand by Hill's 110% because their foods are developed by nutritionists with the appropriate credentials. September 6, 2014
Zd by hills The product works great. My dog suffers from allergies and this is the only thing that has helped her. I just wish it could be more affordable. July 29, 2014
This food has been great for my dog! My dog loves this food and we also feed him the can Z/D Ultra. When he was a puppy and had so many allergeries and finally found a Vet that put him on this food and it worked for my baby so great! Anything else would just break him out so bad and he was constanstly taking shots for alleregies. Thank you from my little Jake. October 21, 2013
Keeps My Dog-Baby Healthy I'm so happy this product exists. My baby dog is much healthier since she's been on this product. Allergies are gone and so are other digestive issues. I just wish I didn't need a prescription to purchase it. And I wish it was not so pricey. July 19, 2014
Bad allergies Hi, nothing seemed to work for what we think are protein allergies in my Giant Schnauzer dog. The moment we started this dog food, 11 years ago he immediately improved. We've since tried other dog foods to see if he could tolerate and he could not...so he's been eating this for a long time. Now that he's older...I also suppplement his diet with the canned/wet z/d ultra dog food and he loves it. Thank you so much for providing this option for my dog...quite honestly, it probably saved his life :) June 30, 2014
This product helps with skin allergies. I really like this product. My pug suffers from severe skin allergies and this food helps. September 17, 2014
