Helps support bones and joint health in older large breed dogs

Promotes healthy digestion through easy-to-digest proteins and a balanced blend of fibers

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.

Royal canin

We have two doodles and this dogwood was recommended by one of the breeders who has been breeding dogs for almost 20 years. Our dogs love it and so do we!

Love it

I have two very picky eaters. And when you have 6 dogs having 6 different foods is not practical. So when I tried this food they all loved it and feeding time was now easier. Thanks for making a great food that has trusting ingredients.

Picky Eater

Ripley is my yellow lab, who is extremely picky and bores easily. After finding out she had food allergies, I was forced to find a food that would not effect her. Blue Buffalo, Natural Balance, Wild something or other...They worked fine for the allergies, but some Ripley would not touch, and others she would eat for a few weeks and then stop. I would have to find whatever leftover in the fridge to mix in to get her to eat. Her brother Jack had a reaction to Doggy IB and was prescribed Royal Canin Renal food while he recovered from kidney failure. SHE loved it, no mix in needed. So we found MAXI +5 and it has been our food for 5 years now. She likes the occasional mix in, but will eat the food plain with no problems or pouting.

My Vet Recommended

My Vet recommended Royal Canin several years ago, and it is all I have been feeding my dogs ever since. Both of my dogs love the food.

Love Royal Canin!

We started our German Shepherd out on the breed specific as a 2 year old rescue and she did fantastic on it. Great coat and easy on her digestive system. As she has gotten older, we switched her to the large breed for 5 plus with absolutely no problems. I love this brand. We also feed Royal Canin breed specific to our Miniature Schnauzer.

Great energy and very happy

My rescue choclate lab had serious urinary tract issues when I first brought her home. We used the Royal Canin SO for a few years and that issue cleared up. As I wanted to ensure that she was getting the proper nutrition, I tried this food and the results are highly positive. Her energy level is outstanding and she is more happy and playful.

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.
