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.

Results speak for themselves

I have been feeding Royal Canin for a year now with amazing results. I previously looked down on this brand because of the ingredients and was feeding my dogs boutique, grain-free food. Both of my dogs (one very small, one very large) are doing 110% better on their Royal Canin diets. Great coats, weight, and muscle tone. My Pyrenees mix is not picky but LOVES this food. The pieces are pretty big, but she doesn't seem to mind. She has an extremely sensitive stomach that I have been dealing with for all three years of her life and this food gives her perfect stools every time. As another bonus, her shedding (if you have a Pyrenees I needn't say more) is much more manageable because her coat is so much healthier. I highly recommend to all owners of large breeds.

This is the only dog food we have found that doesn’t give our dog horrible digestive issues. Thank you for making food that is a healthy option.

Dogs love it.

I have three dogs and have tried many brands and one dog may like the brand and the others dont. It was nice to see that all three liked this food. It's more convenient to buy one bag for all instead of having to buy several different brands.

You know what you are getting.

My dog's mother died at 6 days old and she was bottle fed. I transitioned her to the Royal Canin puppy food for large dogs and then she graduated to the Adult food and loves it! No issues when changing. She has been raised on Royal Canin! I have had a ongoing monthly delivery.
