Product description

Large breed dogs are treasured for being hard working animals and loyal family companions. But as they age, their nutritional needs change. Their large bodies can benefit from a size-specific diet that can keep them happy and healthy, helping them maintain strong joints and large bones.

Royal Canin Large Adult 5+ dry dog food (formerly Maxi Adult 5+) is tailored to support your big dog’s later years. An exclusive complex of antioxidants supports cellular health to help keep your dog going strong. Precise nutrients help keep large bones and joints healthy. Plus, high-quality proteins and a balanced blend of fibers help your big dog digest food easily for digestive health. Add some variety to their bowl with Royal Canin Adult wet dog food. And after your dog reaches their senior years, switch over to Royal Canin Large Aging 8+ for the right support large senior dogs need.

A blessing

My German Shepherd supposedly had allergies and was prescribed a RX diet which is expensive. After years of being extra careful with his diet I looked for something he could tolerate and I found Royal Canin Maxi Adult. He loves the bite size and flavor. I've saved a ton of money as well. Thank you Royal Canin

Healthy and Happy

I have two Bernese Mountain dogs that are eight and five. Royal Canine was recommended to me by their Breeder. The girls have been eating Royal Canine for the past four years. I have tried other foods in the past. One food might agree with one but not the other. Royal Canine is a food that both of the dogs thrive on. They have healthy coats and have plenty of energy for both of their ages. Their bodies seam to adsorb more of the food than other brands. It is the right balance for my girls. I would and do recommend Royal Canine to anyone that has a dog or cat.

I have 3 large mixed dogs. I could never find a "one bag fits all" for them until I found Royal Canin. I also you sensitive skin during the months seasonal allergies flare up. And you know the smaller their stool is the better the nutrients they absorb. Well my yard isn't half as full as it use to be. Royal Canin is awesome and a life saver!!

Great nutrition for any large breed.

Started with the puppy version. My old dog was super interested in this food as soon as I opened the bag. She has a very sensitive belly so I am wary of switching her foods. She is a pit bull mix with joint problems. I had her on some cheap food that was better for her belly but did nothing for her hair, skin or joints. There is a big different now with her skin and hair. The best part is that her bowel movements are normal. Her gas is minimal. Thank god! Those farts would literally wake me up from my dead sleep.

My Dog LOVES this dog food!

My female GSD, who is 7 years old, absolutely loves Royal Canin GSD breed specific dog kibble. She has never been a big fan of dry dog food, but when it comes to Royal Canin, she is in love. She would eat an entire bag in one sitting if I let her, lol. I have never had to do portion control with her until now. Which I dont mind at all; because I know she likes it. I cant say enough good things about this product! Thank You Royal Canin!

Great Food for my 10 year old Boxer

I have been feeding Royal Canin for years! My Boxer started on the breed specific formula, and as she got older I switched her onto the Maxi Adult 5+ dry, she has done so well, has a lot of energy for her age, a shiny coat, and is is good health.
