Supports healthy aging with an exclusive blend of antioxidants for overall vitality

Helps support bones and joint health in medium breed dogs

Nourishes with Omega-3 fatty acids EPA and DHA for healthy skin and coat

Medium-sized dogs are famous for their seemingly endless energy, but as they grow into their senior years, they’ve probably slowed down a bit, and so has their body. With age comes the probability of a dulling coat, and a decrease in energy—sometimes even in appetite. But with a right-sized diet tailor-made for nutritional needs of senior dogs, your dog can thrive.

This Royal Canin Medium Aging Adult 10+ senior dry dog food is made to support your older dog’s vitality. An exclusive blend of antioxidants supports healthy aging and overall cellular health. And because older medium breed dogs may put stress on their bones and joints as they age, key nutrients are included to help keep them playing. Omega-3 fatty acids promote your dog’s skin and coat health to help maintain their youthful shine. And a specially designed rehydratable kibble is adapted for a senior medium breed dog’s jaw, with a highly palatable formula for a meal they’ll love. For variety in texture, Add Royal Canin Mature 8+ wet dog food to their bowl.

I Have New Dogs!

Never have my dogs wanted to eat their food so much! They love this dog food, which only makes that a added bonus to the other great things I have seen change in my dogs since using these product. They also seem like they are aging backwards! They have more energy! I have also noticed that there isn’t as much scooping needed to been done in our yard either!! We have truly found a dog food we will use from now’s great!!

Trustees brand

Our dog has been eating Royal Canin since she was a pup. The brand was recommended by our veterinarian and the only brand we buy. It may be more expensive than the more common Grand however you get what you pay for.

Perfect for my 12 year old baby

I accidentally bought the maxi by mistake but they both have the exact ingredients! What I was looking for primarily was glucosamine, chondritin, and taurine. After just a week I noticed he had pep in his step, and his coat was super shiney and for the first time in years hes eating without a topper! God bless you and Mahalo Royal Canin!
