The best for his breed!!!

This stuff is great! I have a German shepherd, husky mix who has folding the Maxi brand since I got him. I've tried other brands both expensive and inexpensive and nothing compared to this. Nothing agreed with his stomach/digestive system the way the Maxi branding does. Blue Buffalo gave hi excessive gas, pedigree came out the same way it went in. You can clearly see the difference!!

There are so many options to choose from !

My two Labradoodles are 12 and 11 now and they have been eating Royal Canin food since we first brought them home! a couple years ago I did switch to the 8+ food for them since they are getting older but they have been healthy and they really like the food!

Best Senior Food Ever!

My niece is a veterinarian and she recommended this product for my aging dog, Rocco. Soon after he began eating Royal Canin 8+, he's been quite active and his coat is so shiny. Plus, I swear he sheds less too. He gets so excited when it's time to eat. Recently, after filling his dish and brining it up the steps, he actually stuck his big nose into sneak a few bites before placing the bowl down.

Our dogs love Royal Canin

We started with Royal Canin about 7 years ago, we have two boxers. And our oldest boxer was having a lot of allergy issues when we moved to Illinois. We visited the vet, tried lots of different foods. Then tried Royal Canin Boxer blend. And WOW what a difference, the throwing up stopped and the hives stopped. My dogs love the food, and are doing great. No more emergency vet visits because of hives and dehydration. My older dog is not having joint pain issues. We have switched them to Royal Canin 8+, and my pups are still doing great. I definitely recommend Royal Canin to all my friends.

Old dog has more life!

I started giving this to my 12yo Bassett Hound 6 months ago. After a month, he started to be more mobile and active. Now he runs and plays with my 2yo German Shepard.

Only the best for the best!

I bought this a few months ago for my 10 year old Pyrenees mix. He had been slowing down and was showing his age despite medical management for osteoarthritis an DJD. I CANNOT believe the difference this has made in him! After about 30 days on the food he is much more spry and playful with my other dogs. The biggest difference- he jumps! He was never a dog to jump into the car or the bed even in his younger days and he does now- with confidence! The only difference was the food. It almost brought tears to my eyes- thank you Royal Canin for bringing new life to my boy!

Wonderful Selection For Very SpecificDogs

When we brought our Wired Hair Pointing Griffon puppy home from the breeder in May 2018 she highly recommended Royal Canin max puppy chow since he was 18 pounds. Five months later he weighs 65 pounds, has great energy, a wonderful coat and eats his Royal Canin Large Dry Food so fast that 2 cups are gone in less than 1 minute. Our Vet & Dog Trainer also highly recommended that the best dog is is Royal Canin.

Easy to chew

Been using Royal Canin dog food since our German Shepherd Angel was 6 mos old we had to put her on adult dog food because of birth defects. She just loved the adult food but when it started to get hard to chew we switched her over to the aging dog food. The adult food was a star shaped about an inch in diameter but the aging food was a oval shaped O that was easier to chew. She ate this food up until we had to put her to sleep at 13 1/2 yrs old. All Royal Canin food stayed with her not like the other food where she would have to go the bathroom 2 to 3 times a day this food she had her regular bathroom goings once a day. And our dog was very picky on what she ate this passed her pickyness because when we would take her to the vet the vet would give her treats she would not eat them at all. Thank you Royal Canin for being here in the time of need.
