Rated 4.8 out of 5 by 10 reviewers.
Rated 5 out of 5 by Great for my smallest! Ember is my smallest pomeranian, and my oldest (though we can't be 100% sure of her age). She is a rescue, and wasn't always taken care of well. She's been eating Prescription Diet t/d for years, but last year she lost most of her remaining teeth during a routine dental. Without matching teeth to chew even the small bite kibble, I began researching other diets for her. The Small and Toy Breed Age Defying diet is easy for her to eat, and she loves it! May 19, 2015
Rated 5 out of 5 by Only food my dog will eat I tried many dry foods, but this is the one my pet prefers October 13, 2015
Rated 5 out of 5 by 100% improvement I have 3 senior dogs, the oldest is 15. Since changing them to this formula they have showed great improvement. Their coat is softer and healthier, they have more energy and don't eat as much now. They all love it and my newest addition we rescued from the local shelter who is our foster dog even loves it and her hair stopped falling out and has shown much improvement over all. Great dog food all around September 17, 2015
Rated 5 out of 5 by Great size bites for the little guys After years of eating wet food, I was not sure if my senior dogs would accept a dry formulation. To my surprise, they loved it!! I am glad that my veterinarian suggested a change to both a dry and a senior formula, and recommended Hills. Thanks for making a yummy food for my doggies! September 7, 2015
Rated 5 out of 5 by good food my pug is elderly and most foods are too hard on her digestion. This one has given her no problems, she looks and feels great and she actually likes it, which is cool since she's quite picky. August 7, 2015
Rated 5 out of 5 by mature small /toy dry food This has been a great product and our dogs love the small bites and the great taste. April 3, 2015
Rated 4 out of 5 by My dog has a burst of energy My pet is 13 years old and since changing his food he is really happy and eating all his food. He would be lethargic and without any energy before. December 19, 2014
Rated 5 out of 5 by She has lost a lot of teeth, only likes small bites. When I got her as a puppy, I tried many other types and brands of dry dog food (she refused to eat for a couple days)and finally the Hills brand was the only one she would eat and it had to be the small bites as she was a little dog. She has been on Hills every since and she still wont eat other brands of dog food. June 30, 2013
