Product Reviews
Royal Canin ® Size Health Nutrition ™ Large Adult dry dog food is rated 4.9 out of 5 by 92.
Rated 5 out of 5 by from Happy and Healthy We adopted our sweet Sally from a shelter just over a year ago and they recommended Royal Canin. She was underweight and quite sickly when we got her. After some veterinary care and continued use of Royal Canin food she is happier and healthier than ever. I attribute her "perfect weight", as our vet says, and her soft fur to this product. We will NOT be switching her food anytime soon!

Rated 5 out of 5 by from Great food all around! I have been feeding my Doberman and my lab this food for the past 4 months now and I am so pleased with the results. We have tried so many different brands and after our dog trainer at Cobra Canine recommended this one, we gave it a try and couldn't be more pleased.Both of our dogs have sensitive stomachs and dry skin and this food has been the only one that we have found that works for them both!!! Their coats are looking better than ever and they both seem to be felling a lot better too.

Rated 5 out of 5 by from Both my dog & cat love Royal Canin My 2 year old Australian Shepherd loves this food! I started Owen on Pedigree when I first brought him home and it just wouldn’t sit well in his tummy. Recommend by a family friend, Royal Canin has been a great food for his high energy, caloric needs and of course his long hair. He enjoys both the Adult Maxi Dry food as well as the adult wet canned food. He’s never been happier with his food!!! :) When I adopted my cat Milo I immediately decided that he was going to also eat Royal Canin. I started him off with kitten dry food and gradually added the canned kitten wet food in gravy. Now, I buy both the wet and dry food for Milo as he enjoys the wet food as a treat once a week :)

Rated 5 out of 5 by from Another great recipe Untill I began working at petco my cats and dogs were on your typical grocery store brand pet food. After becoming educated on pet nutrition I decided to give this brand a try. My pets have never been happier! They have more regular stools, their skin and coats have never looked better, and I feel happy knowing I'm doing my part to give them a longer happier life!

Rated 5 out of 5 by from My Big Dawg loves it Ive been using this product since. My dog was a puppy. It has kept him very healthy and lean. His coat is soft and beautiful, and his energy level is up. This food even has helped with is tummy troubles. Being a Mastiff finding a food that doesn't make his digestion poor is hard to find. (tried uploading a pic of our giant Mastiff but it won't let me

Rated 1 out of 5 by from Where is the meat? Large breed Dog need GOOD protein, and NO CORN or WHEAT as they both contribute to arthritis! This does NOT qualify as a good food by any means.

Rated 5 out of 5 by from Great large breed food I have been feeding this to our Bernese Mountain Dog for close to a year now and she loves it! We switched over from the Science Diet Large Breed (also a great food- just didn't work for her). She loves the taste of this food and even lost a little weight when we switched her over!
