Product Reviews
Royal Canin ® Size Health Nutrition™ MEDIUM Adult dry dog food is rated 4.6 out of 5 by 50.
Rated 5 out of 5 by from Only thing my dog will eat! I tried so many other dry foods and either he wouldn't eat it or he got diarrhea from it. My vet recommended this and I balked at the price.'s actually quite reasonable, particularly considering all the food I had to throw out. He loves this food and sits with his head over the bag when I open it up. I won't feed him anything else, and it makes me feel good since I know he's getting the proper nutrition!

Rated 1 out of 5 by from READ THE INGREDIENTS Second on ingredient is "chicken by product". Completely horrible they are promoting well rounded nutrition for your pup but the first ingredient is Brewers rice and second is a meat by product. Similar to any big box dog food like purina don't spend extra money on something like this. Look at what exactly is actually in this food because not much is natural or what they claim to be producing.

Rated 5 out of 5 by from Soft Coat We have been feeding our Queensland Healer / Boarder Collie this food since she was 11/2 year old. She is now six years old and her coat is as soft as ever. We get people asking how we get her coat so soft and I have to give the credit to Royal Canin.

Rated 5 out of 5 by from Excellent Food, Quality Ingredients! I love Royal Canin products!! My dog is a shepherd mix and I've always debated on if I should feed him the medium dog food or the german shepherd food. He has been on the medium food now for a little over 2 years (after feeding RC puppy until he was about 8 months) and it has been an excellent food. My pup sometimes has tummy trouble if he eats too many rich dog treats and this food (or occasionally RC prescription bland food) has done great to get him back on track! He also absolutely loves this food and is super excited for meal time! I have been feeding my pets Royal Canin for about 6 years now! I can't tell people enough how much I love it! My pets have always loved the food, even my picky eaters. Royal Canin does extremely extensive research about ingredients and nutrition to best fit the needs of each and every pet. They are always focused on keeping up to date on new recommendations and standards within the veterinary industry and not focusing on the fads/trends in the market that don't do your pet any good. Royal Canin is also very open and honest about their products and always welcomes questions or concerns to better serve their customers and their pets!

Rated 5 out of 5 by from Fantastic! Will never feed them anything else! I look at buying dog food as like buying food from me. If I can get a 50lb bag for $25 from a grocery store, I feel like I'm buying them what Fast food does to me. I switched to Royal Canin 2 years ago and I will never change it. My 2 dogs love it! It makes there coat super soft and shiney too. They are crazy energetic girls. We even use pieces of food as training treats!

Rated 5 out of 5 by from My dog loves it! I have been feeding my 6 year old dog this food for about four motnths now and he absolutely loves it. His coat is shiny and the dry skin he had before I got him has totally resolved. His weight is perfect for his age and build thanks to this food, and he has had no GI issues with it whatsoever! I couldn’t ask for a better dog food!

Rated 5 out of 5 by from Best Dog Food My be-loved Max has Royal Canin since he was 2 month. He eats this dog food for 12 years, he never got sick, his skin is smooth, and he's still running like puppy! I think Royal Canin help me having a health pet and save my money of vet visit, and keep him younger. I am so glad that I listened to a vet when I adapted Max.

Rated 5 out of 5 by from Little waste! My breeder fed the Royal Canin medium puppy food and we continued that regimen. We then switched to the Adult dry food. Our dog is a 35 lb Soft Coated Wheaten Terrier and she looks great. She has little waste in our yard so I know she is metabolizing the food well. She is 2 1/2 now. Our vet said she is in great shape!

Rated 5 out of 5 by from Dogs eat it Never had any digestive problems with this food. The dogs have always eaten it. It isn't a high end dog food that costs lots of money but it is pretty good. I did research foods before feeding them to our dogs because I didn't want all the chemicals that can be added to cheaper foods.

Rated 5 out of 5 by from Healthly dog = happy owner My vet recommended that we switch to Royal Canin after I pointed out that our new dog did exactly like our old dog - threw up after eating. Tate does not throw up, loves her food and we have noticed an additional benefit - a non-gassy dog! Her improved health is obvious!

Rated 3 out of 5 by from Good until... My dog has been eating this for the last three years and was fine. Recently, however, she developed a food sensitivity to it and we’ve had to switch to something else. Otherwise, she seems to enjoy it and it seemed to meet all her nutrition needs.

Rated 5 out of 5 by from The quality is obvious! I have had my 3yo, 50 lb staff mix on this food for about a year now and she's always been excited to eat her food since I started her on this. Her skin and coat has improved and her poops are always healthy!

Rated 5 out of 5 by from Our dog loves it! We used this product for 2 years and our dog loved it! Kibble is a good size so Charlie had to chew rather than inhale. No digestive/gastrointestinal issues, highly recommended.
