Large kibble!

[This review was collected as part of a promotion.] 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 :)
Royal Canin response
Great feedback and suggestion, thank you!

Huge Kibble Size

[This review was collected as part of a promotion.] 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

[This review was collected as part of a promotion.] 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.

Giant breed food

[This review was collected as part of a promotion.] It's great to have dog food specifically for the big breeds. We have a Scottish deerhound and an Irish wolfhound, so we need a nutritional food for them.

Excellent results

[This review was collected as part of a promotion.] My large doberman has been on this food for 30 days now and his coat is so soft and shiny, he plays wother his little sister more every day. He loves the taste and the large kibble size with no woofing it down like the smaller kibble. No digestive issues that he has had with other foods. Love this food and the excellent results.
