Love it

Amazing food! My dog loves it. I have been using this for over one year. Thank you!

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.

Great dog food

Both dogs love the taste but don’t over eat b/c they get full quickly and are able to maintain weight. Love that it has the nutrients to keep them healthy as they are getting older

My dog loves this food!

I switched my 8 year old pitbull/boxer mix to this food and she loves it! She has been a picky eater with some constipation. She is eating great, and having regular stools just a month later!

Great for my aging GSD!

I finally found a great balance for my 8 year old GSD with skin and hip issues. I needed a food to support his joints, keep him lean and help his skin barrier against allergies. This food has done it all! I love the science behind all of Royal Canin's diet's and and thrilled to have found the one perfect for him!

Love it!

My 9 yr/o Labrador Jack never leaves the bowl empty. The bigger kibble makes him take his time. Since he has some food allergies Royal Canin has never had any effects on him from the Puppy to the Senior. After 9yrs I still have people telling me he looks so healthy and love how soft and shiny his hair is. He also has healthy gums and teeth!

Couldn't be Happier!

My GSD has been eatting Maxi 8+ for over a year now. His skin and coat look great! He loves this food and we couldn't be happier with the results we have seen
