Finally, a food that works!

I have had my mixed breed dog for about 3 years now, and have tried him on almost every food you could think of. On all the grain-free stuff he had wet, yellow stool, and once I switched to the grain-inclusive he did better, but not great. He did very well on Eukanuba, but I was looking to switch it up and thought why not take it one step up and try RC? Well I'm glad I did! My dog loves the food, he is a good weight, he only poops 1x daily, and his fur is soft and shiny even a month after a bath! I am so excited to finally find a food that works for my boy and I will not be switching again!!

We switched our dog to Royal Canin after MUCH research. He was on a grain free food and we were scared regarding all of the reported heart issues that could be linked to grain free / boutique type foods. After our research and reading the Royal Canin website (especially the Science Based Nutrition Page) we made the switch. Theo’s BM’s are much firmer and much less volume than when on grain free food. His coat is also softer and he seems to have endless energy. He also loves the taste of it.

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!

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!

Love it

MY DOG REALLY LOVE THIS FOOD! Since it was a puppy, we tried one other brand and it stopped eating. We went back to Royal Canin

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!
