Hill's® Prescription Diet®
z/d® Canine ULTRA


Adverse reaction to food.

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.

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

  • Use only as directed by your veterinarian. Cover and refrigerate unused portion.
  • 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 dry food and treats, decrease the amount of canned food to avoid overfeeding.
  • Keep fresh water available at all times!
  • For best results, have your veterinarian monitor your dog's condition.

My dog loves ZD. Finally found something my Shih Tzu enjoys eating and it has put an end to his constant itching and chewing himself. It is expensive but it works. After having ZD he is willing to then eat his dry food. September 22, 2014
Excellent product The love of our life, Primo, is a 91/2 year old Cock-a-poo. He has always had serious food allergies and we had a very difficult time when he was a puppy finding a food that agreed with him. Our veterinarian suggested the Hill's Prescription brand products and it has been the right answer - he no longer has a negative reaction to his food. Now, he looks forward to meal time and he LOVES his food! Thank you for such a wonderful product. July 19, 2014
Sensitive 14 yr old Shiba going the distance with z/d. My 14 yr old Shiba Inu has developed sensitivity to her regular dry food. So, to keep her from vomiting/diarrhea seesawing our vet suggested the z/d canine Ultra, and it is working for her. We give her 4 small meals per day so that the food does not overwhelm her gastrointestinal system. I mix it into small bits with a little white rice, a tablespoon of firm tofu, and a little water so that she gets her food and a gravy-like fluid. Sensitivity at old age takes longer to adjust so she gets about 1 can per day, spread out over a 12 hr. period. It is good to see her chipper and comfortable again. January 4, 2014
No More Diarrhea Buddy started having unexplained diarrhea that lasted almost 6 months without any relief. Our vet had us try many different things and many tests were done. it was finally determined that he most likely had a food allergy so he was prescribed a Z/D diet (can & dry). His diarrhea stopped immediately and hasn't returned in 2 years. Buddy was a very picky eater before (maybe the other food made his tummy hurt?), but has never once passed up a Z/D meal. He gobbles up this food like it's a steak dinner. Since he is on such a strict diet it was hard finding a treat that wouldn't mess up his stomach. We decided to try and bake the Z/D canned food and had great results. We just slice up the can food and bake at 350 on each side for 16 minutes. The smell is terrible, but these make really great treats for a dog with a sensitive stomach. Our other dogs love them as treats too! September 3, 2013
the product is worth the price My sam a yorkie had bad allergic reactions to regular food that cause bad diarhea... when he started to eat this food , it stop instantly the diarhea and he is happy , healthy before he was miserable... I just wish they had a smaller kibble in the dry (small bites ) so my dogs would eat the dry... right now it is very pricey going through 2 cans a day.....but worth the result ... It is very worth it...... hills please please consider making a small bites in the dry.... Thank you.. February 8, 2013
One of the only foods that my dog can eat! My dog was recently diagnosed with allergies - and this is one of the only dog foods that he can tolerate. He looks so much better, and has a lot of energy now - he is back to his old self. November 11, 2014
Soothed our dogs stomach Our dog tolerates this food better than any other food he has had in years including homemade chicken & rice with supplements tailored for his age and weight. We have seen a definite improvement in his ability to keep weight on and be comfortable. I would recommend this to anyone whose dog has food intolerance. Seeing is believing. After trying everything else and a weight loss of 7 pounds this ZD ultra canned brought up his weight and condition. For a dog that normally weighs 93 pounds it is expensive but at age 13 years we are happy and grateful to Hill's for this product. He loves the hypoallergenic treats too! August 19, 2013
Great product I have a Westie who couldn't seem to tolerate any kind of food I offered him. He would eat and promptly vomit most of it up. I took him to the vet and they put him on the Z/D prescription diet. He has been on it since he was a puppy. He gladly eats it right down. Thanks for a great product. October 16, 2014
