With a big heart and playful energy, your gentle giant has it all… shouldn’t their nutrition? Extra-large dogs put a lot of daily stress on their joints due to their sheer size and can benefit from a formula that supports digestive health. These giant breed dogs need a size-specific formula to help them live a long, happy life.

Royal Canin Giant Adult dry dog food is tailored to support your dog’s commanding presence and lifestyle. This giant-breed formula contains glucosamine, chondroitin, and EPA/DHA to help keep bones and joints healthy and strong. An exclusive complex of antioxidants supports cellular health. Heart-healthy nutrients like taurine help keep big hearts healthy. High-quality proteins and a blend of fermentable and non-fermentable fibers help support optimal digestive health. Plus, the extra-large kibble encourages chewing, so big dogs can properly digest their food. Add some variety to their bowl with Royal Canin Adult wet dog food.

EXCEPTIONAL EFFECT ON HAIR,SKIN AND DIGESTIVE

I have been buying this for 1 year now and the positive effects on my dog was visible from the first week. My favourite part is the size of the pellets. Buddy gets to actually chew his food.

Large kibble!

I absolutely love this food! Finally a kibble size for giant dogs! My boys no longer inhale their food and with RC we know we are feeding the best to our boys! Thank you! I only wish the prescription diet my other giant needs would come in a larger kibble size :)

Huge Kibble Size

My African Boerboel Mastiff had a hard time with previous "large" kibble, it would fall out of his mouth and was a mess, this is a perfect size, his coat and weight are great!

Great Features and Tasty and Most Liked Food

when i first get my puppy, its an saint bernard its only 2 months old. and breeder tell me that they feed them only Royal Canin and give me advice to keep your puppy healthy you should have to feed them Royal Canin at least 6 months. But now my dog is 1.5 years old and i still feed them Royal Canin and their health is faboulsy and they are maintained dog. I suggest everybody to feed them Royal Canin for their lovely small puppies. I also want to thank Royal Canin for giving us a great and wonderfull and healthy food to keep our babies healthy. also they have all ingretients which is required in large breed like calcium for joints or good oils for their skin. Thanks.

Huge bites for huge appetites

My BF was feeding his senior St Bernard something inexpensive that was "natural" and I noticed that he did not eat with much gusto. I ordered a bag of this and 1st- a picture of him was on the bag! 2nd- The kibble are sized for him to be able to grab and actually chew ( a little) and 3rd- He obviously preferred the taste. He was underweight and his muscles had some atrophy. Now his back legs seems to have filled in and his coat is so shiny.

Best food for dogs

My giant breed dog has been eating Royal Canin since she was born 3 years ago. She has never had any problems and grew to be a beautiful dog.
