Perfect for St.Bernards

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

Huge kibble

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

Picky eater

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

Great for my dane!

I adopted a four year old dane eight months ago and she had a very dull coat with some really wiry patch that was going a bit brown coloured (she's black). Since switching her to this food the brown, wiry patch has gone and her coat is shiny and soft. I like the size of the kibble too as it encourages her to chew her food and has helped her teeth. Overall a very good food, even my little maltese x tries to steal it so it must be tasty as well! Only downside is that I'm from Australia and it's very expensive to buy it here.

The ONLY dog food w/ charcoal brisket sized nugget

[This review was collected as part of a promotion.] Have used this brand for years w/ my 1st and current Old English Mastiff(s). Both suffer(ed) from allergies and sensitive stomachs (as well as some seriously potent gas!) - but after switching to Royal Canin's Giant Breed dog food, the gas & diarrhea was eradicated. Plus - they gobble it up like nobody's business! Can't necessarily say it helps w/ the allergy sitch, but I don't think there are too many commercial foods that do….

My Saint's preferred food

[This review was collected as part of a promotion.] My rescued St. Bernard dog really finds this food delicious....she heartily munches the nuggets. She has gotten stronger compared to her emaciated state I got her, and her hair has fully grown.

Healthy and Happy

[This review was collected as part of a promotion.] There aren't too many choices for giant breeds.After being told by our bets and the breeder as well as reading several articles, we concluded that it was important to feed our Newfoundland something designed for his size dog. We started out with Royal Canin puppy food and quickly noticed how shiny his coat got. Just to compare, we switched one of the very few other options available for giant breeds, and again, quickly noticed a change in his coat, this time for the worse. We switched back to Royal Canin and he's now moved from puppy food to junior to adult.

Amazing food

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