Rated 4.9 out of 5 by 23 reviewers.
Rated 5 out of 5 by Delicious Food. Our Lakeland Terrier loves her food. She is satisfied. Happy and bouncy. Our two male Lakeland terriers love to steal a taste of her kibble. Many thanks for a great trusted product. October 7, 2015
Rated 5 out of 5 by You know what is in the food It's limited ingredients to help with skin conditions. You know what is in you dog's food. If you have a question, all have to do is call the number on the bag. They tell you every single ingredient, they don't tell you "it's classified." May 19, 2015
Rated 5 out of 5 by Helped with allergies. At the age of 2 years, my GSD developed ear infections and began chewing his paws due to a food allergy. After trying several commercial foods with limited ingredients with no discernible improvement, I opted for Hills d/d potato and duck and he has had no troubles since. The d/d formula also maintained a healthy weight for him, which was important as he was in the conformation ring and herding arena as well. He's doing great! October 9, 2013
Rated 5 out of 5 by A uniform consistant diet that meets my dog's requirement for a single protein food. The food keeps my dog healthy though he does not eat it with relish. Recent significant price increases prevents me from rating the food an excellent buy. October 6, 2014
Rated 5 out of 5 by This food has many flavor options for my pet. I have an white/tan pit bull with skin allergies and have been through a series of different medications and foods until being put on d/d. The change in his skin and coat was amazing and he has barely been on any medications since the diet change. I highly recommend this diet if your pet has allergies but also for any other reason, Hill's has great quality foods! February 4, 2014
Rated 5 out of 5 by My dog has protein allergies. Thd d/d duck and potato food works! My 6 month old Lab/Chinook mix has an allergy to some proteins in regular puppy food and would end up with diarrhea. My vet and I tried different puppy foods, including sensitive stomach puppy food but we always ended up in the same condition, with an inflammed intestine and needing meds to calm it down. Since my vet had me try the d/d duck and potato formula, he's not had any relapses. December 7, 2013
Rated 5 out of 5 by Awesome My dog enjoys the food. It seems to have helped with her allergy issues. It is expensive!! September 15, 2014
Rated 4 out of 5 by This product is a well balanced limited diet. The ingredients are consistant and have brought a rescue Dane with numerous allergies back to full health with a wonderful shiny coat. September 9, 2014
