Customer Ratings & Reviews

Rated 4.6 out of 5 by 156 reviewers.
Rated 5 out of 5 by First food my pet has eaten with no digestive problems! My little Yorkie has had allergies & taken medication for it since I have owned him. My new vet suggested that I convert to the Science Prescription ZD diet to eliminate any potential for food allergies with the goal to eliminate his allergy meds. Well this food has done it! He loves the dry food & has just thrived. He has not needed his allergy meds for two weeks now. His coat is so shiny & healthy & he had no problems with the conversion. February 1, 2014
Rated 5 out of 5 by Solved a Digestive Problem We have been using this food for about a year and the results have been excellent. Solved a chronic digestive problem and Sammy now enjoys great health and I am sure has a happy colon. January 30, 2015
Rated 5 out of 5 by Z/D Canine has put weight back on our dog Our dog was having major digestion problems and loosing weight. The veterinarian thought she might have stomach cancer, but we switched to z/d dry and she is healthy again. December 22, 2013
Rated 5 out of 5 by This food is amazing Both of my rescue dogs are on z/d. It has helped both dogs with ear infections and skin conditions! February 25, 2014
Rated 5 out of 5 by Dog loves it My dog was having severe g.i. Problems to the point we thought that she was going to be put down or just die .vet advised that we try zd wet food 2weeks-ago she a new doo no more skin problem no more GI bleeding or vomiting .it gave her a lease on life. January 10, 2014
Rated 5 out of 5 by It works, but bites are too large! My Maltese has allergies, specifically gummie ears. This product has helped tremendously. The bites are very large for a dog her size. My vet tells me they don't have a smaller bite. Is this true and if so, what would you recommend I do to help make the chewing process easier on her? December 14, 2013
Rated 5 out of 5 by INSTANT ALLERGY RELIEF ......For several years, we have tried many medications to try to rid Phoebe of her itching and scratching problems. Her treatments have included several allergy tests, prednisone tablets and cream, cyclosporin, special shampoos. Not to mention many Vet. visits. One Vet., even suggested "putting her down". That was not an option! Within a week, after starting her on Hill's ZD dry food, her scratching has all but ceased. The ugly lesions are quickly clearing, her coat looks healthier and she has even shed a few pounds.(needed) Had someone suggested Hill's, "early on", we and Phoebe, could have eliminated a lot of "angst". "Hill's to the Rescue" December 14, 2013
Rated 5 out of 5 by Worked wonders for my dog's allergies! I have a five year old dog that developed a protein allergy. My vet recommend this product and I have seen amazing results. Her beautiful coat is back and her itching is significantly reduced. March 10, 2014
