Rated 5 out of 5 by from Amazing food I have two Dogue de Bordeaux and after the breeder and vet recommending this it is all I have feed from day one. I love it and so do my dogs. It is all I ever will use anymore.

Rated 5 out of 5 by from Great for gobblers! The size of this food is excellent if you have a giant dog that likes to "inhale" their food. Giant breeds have a lot of issues with "bloat" or a twisting of the intestinal tract, among other reasons, this can be brought on by eating too fast and not chewing their food properly. The large briquet design of the Royal Canin Giant Formula forces the dogs to slow down and chew...I love it!

Rated 5 out of 5 by from Growing girl! Our Great Dane had been on gastrointestinal food for a few years before we heard of the Giant Breed food. During the transition phase we didn't have the usual tummy upset with diarrhea or gas, now she is completely on this diet and looking great! She's 9years old now, shiny coat and perfectly healthy with no signs of arthritis yet.

Rated 5 out of 5 by from Great product My dog has been a very picky eater since she was a puppy, hard to imagine for 160 pound English Mastiff. We have tried several foods through her junior years to get her to eat better but the one we kept coming back to was Royal Canin. She has now been on Giant for the past 4 years and loves it. I wouldn't try anything else. Well worth the money for the quality of product. Ms. Annabelle approves!

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.

Rated 5 out of 5 by from Picky eater I have a Great Pyrenees who is a very picky eater. She loves this food. The pieces are giant sized which forces her to bite and chew her food. I love the size of the bites. I also have the food delivered to my doorstep which is also very convenient for my schedule. All of my pets are on Royal Canin absolutely love their products.

Rated 5 out of 5 by from Huge kibble Love that Royal Canin has such well tailored diets. They even make the size of the kibble huge so giant dogs actually have to chew. I trust that the research they have put into every small detail means that my dog is getting exactly the nutrients that she needs. The food is expensive but worth every cent.

Rated 5 out of 5 by from Produces a great coat My three-year-old Bernese Mountain Dog has always been fed Royal Canin Giant products. His littermate has not. Their coats are noticeable different; my Norm has a silky, jet black coat that's always shiny. He's in great health, thanks in part to Royal Canin Giant.

Rated 5 out of 5 by from Perfect for St.Bernards I bought this for my st.bernard Ellie. She absolutely loves it! The bigger kibble fills her tummy up faster and she isn’t eating as much as smaller kibble. She takes her time chewing each piece and eats every bite!

Rated 5 out of 5 by from Giant breed food 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.
