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

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.

Happier and Healthier

I recently switched from Iams Large Breed (which I still love and think is a reputable complete and balanced dog food) to Royal Canin Large Breed. My dog Mickey (silver lab) ate Iams the first 2.5 years of his life but was never super excited about eating. He of course always ate when he was hungry so I was never too worried about him but it was hard to get him on a routine eating schedule. I tried out Royal Canin Large Breed and now he finishes his bowl as soon as I fill it! We had a little bit of a learning curve with how much he should be getting compared to Iams but we're now on the right track.
Royal Canin response
Great to hear that he loves his food and thank you for the pictures!

My dogs are super healthy

A few yeas ago, a buddy of mine told me that one of his friends that was a vet said that there's no point in buying the more expensive stuff and that it was all the same. I asked my vet about this and here's what he said. "Your dogs are always very healthy so whatever you are doing, keep it up." What else did I need to know?

My dog loves it

I have been using this for almost two years. Great product. I use it with the Royal Canin wet food for a nice daily treat for my dog.

Eaten Quickly

Our puppy has been on Royal Canin since we got him at 8 weeks. He has moved up to the adult and loves it. Not a morsel left. He has grown as expected and is very healthy.

Only the best

My bear has had royal canin dry food from the moment he went onto solids. I have to say I am a first time royal canin user (always used other brands) but it is great. My boy loves it, he has great skin and his fur is soft and shiney (atleast when he hasn't been running through muddy puddles!) His growth has been steady and he has a good amount of energy without being hyper on additives. His doggy family also all love it. Definitely would recommend it.

Fantastic for all ages!

Our breeder raved about this product, and made it a requirement part of our guarantee. Our dog has grown and developed at a healthy rate, and devours each meal (Labrador Retriever). Will continue beyond our breeding contract requirement.
