Promotes healthy digestion with easy-to-digest high-quality proteins and a balanced supply of fiber

Helps support bones and joint health in large breed dogs

Nourishes healthy skin and coat with EPA and DHA

Exclusive large-sized kibble design is highly palatable

Large breed dogs are treasured for being hard working animals and loyal family companions. Whether they’re on the job or playing in the backyard, they lead active lives. Their large bodies benefit from a size-specific diet that can support them with the energy they need, to maintain strong joints, and nourish a healthy skin and coat.

Royal Canin Large Adult dry dog food (formerly Maxi Adult) is tailored to support your big dog’s active lifestyle. This exclusive formula contains an optimal balance of high-quality proteins and fiber for optimal energy and digestive health. And because large breed dogs put a lot of stress on their bones and joints, key nutrients are included to help keep them playing. Omega-3 fatty acids, EPA and DHA, help promote your dog’s coat and skin health. Plus, this diet’s exclusive kibble is designed for large jaws, with a palatability that’s sure to please. Add some variety to their bowl with Royal Canin Adult wet dog food. And when your dog reaches 5 years old, switch over to Royal Canin Large Adult 5+ to fight the first signs of aging for a happy, active mature life.

The best for our dogs!

Both our Lab and German Shepherd are Healthy, Active and Happy! We love this brand and have used it for over 4 years now. Our dogs love it and the vets have nothing but good when it comes to our dogs health. Would recommend indefinitely.

Nutritionally balanced

I switched my girl to this at 18 months old after the FDA announcement concerning BEG diets and DCM. I love that it comes in resealable bags, but do wish it was a little more palatable. Sometimes I have to add canned food as a topper to get her to eat it.
