Product Reviews
Royal Canin ® Size Health Nutrition ™ Medium Adult dry dog food is rated 4.8 out of 5 by 107.
Rated 5 out of 5 by from Great dog food. I was buying this dog food and both my german shorthairs were doing fine on it. Our trainer recommended a brand he sold, so we tried it. To our dismay, our dogs were allergic to its ingredients, their coats looked terrible, and lost weight. We went to the vet for the skin issues & he said go back to what we were using. Half a year later, the dogs have gained back their weight & their coats are beautifulagain. People from all over the country that we see at field trials and hunt tests ask what we feed our dogs because they look so good. We're highly satisfied.

Rated 5 out of 5 by from Excellent food, very palatable, dogs look great! I buy RC Medium dog food for my dogs, who exhibit in AKC Conformation shows regularly. They need a food they will reliably eat, and that will keep them in prime condition. This food fits the bill! Even when in the car all day heading to a show, or at a large show with lots going on, I know my pups will readily eat this kibble. No more stress-induced hunger strikes! And of course they all look fantastic, shiny coats and in good condition.

Rated 5 out of 5 by from Excellent food! My girl, Lacey had been on this food for almost 2 years and she has thrived. Her coat is lovely and shiny, teeth, nice and white. But to be honest, one of my favorite things about the Royal Canin diets is how efficient they are, in that there seems to be very little stool production. She is SO regular, her once-a-day gift that I can easily expect and clean up on our walks! It's a not-so-little thing that makes me very happy!

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 Medium Adult works well We adopted 2 dogs a year ago from a shelter. The food they were on seemed to cause GI issues. We had our last dog on Royal Canin Large breed for 9 years and knew we would switch the 'ladies' to it. I trust Royal Canin to always put the health and nutritional needs of our dogs first!

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 The perfect food, well worth the price We started our puppy on this and then tried a few cheaper foods, he got sick or had an upset tummy on all of them! We waited out until he finished that bag and went back to Royal canin. truly the best dog food, it is worth the price. he loves it! The only thing that he wishes was better is smaller pebbles for adult dogs! when he was a puppy he loved the size and once we switched him to adult food, he wanted the small sizes. other than that it is a great food

Rated 5 out of 5 by from My dogs can’t get enough! We switched our 2 dogs to this about a year ago due to some lab abnormalities seen at checkup for our dog, Bart. He is doing better than ever and our other dog loves the food as well... she has always been a picky eater but we have no doubt she likes her food now. In addition, this brand is slightly less expensive than the food we were using before. Such great food for a reasonable price! We won’t feed our dogs anything else!

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! After trying my Dalmatian on the breed specific diet and finding his weight difficult to manage (he was getting too fat!) we switched over to this diet. This diet agrees with his tummy and he has very healthy stools, his coat looks fabulous (we get compliments on how soft he is all the time!) and best of all, he’s at a healthy weight and is very easily kept there!

Rated 5 out of 5 by from We love Royal Canin! I adopted my husky mix, Jude, 4 months ago. Our vet recommended this diet, I already have my cats on Royal Canin, so I trust the brand. Jude has a husky housemate who is on a different diet and the difference in their coat is amazing. Jude is softer, shinier, and sheds less. It's also VERY palatable, we use the kibbles as training treats.

Rated 5 out of 5 by from Love it It’s great that the food is formulated for my pet. More of what she needs and less of what she doesn’t. And I love that this food will age with her. That way she can stay on it long term and I can avoid stomach upset as she gets older. Royal Canin as a company is impressive as well. From the customer service to the product, all wonderful.

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 Picky Aussie Approved!! My 2 year old Aussie is super Picky, but she really liked her RC food!! It all started when she was a puppy & had bladder stones. The vet put her on the special RC veterinary diet for her condition, and she loved it! Once she was able to go back to regular food, we switched to the regular Adult. No Complaints from Mayzee!
