Product Reviews
Royal Canin ® Size Health Nutrition ™ Giant Adult dry dog food 35 lb bag is rated 5.0 out of 5 by 34.
Rated 5 out of 5 by from Healthy and Happy 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.

Rated 5 out of 5 by from Wouldn't feed anything else again. I had been feeding my Saint Bernard a different brand for several years but it seemed like they switched the formula because the last couple bags I had bought really upset his stomach and gave him the runs. I didn't get to mix the food at first as directed because I wanted to get him off the other kind right away but he seemed to feel better really quickly after switching. He eats this food no problem and I love the large kibble because now he actually chews his food instead of inhaling it! My grandma came to visit about 2 months after I switched, she hadn't seen him in a while and all she could say was how much healthier he looked. For being 8 he still gets around great and seems to be doing awesome on this food.

Rated 5 out of 5 by from Love that it's specific for giant breeds I just switched Finn from the giant junior food to the giant adult. He had a little trouble with the size of the kibble at first (pizza roll size) but then he figured out he needed to chew his food.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Love this food I won't feed my Great Dane anything else. (Unless the Great Dane breed specific diets makes its way to the US). He absolutely loves this food. On another diet he was eating 10 cups a day, his coat was dull, energy level was low, and he constantly was passing large amounts of stool. When we switched to this he started eating less (4 cups a day!) His coat shines, more energy, and so much less stool. I highly recommend this diet to those that have giant breed dogs. Now all 4 of my fur babies eat Royal Canin

Rated 5 out of 5 by from Quality Dog for Health of Giant Breeds I watched a video about how Royal Canin is formulated. Very very informative. Most other dog foods draw us in by emphasizing what is appealing to humans not what is important for the health, digestion, absorption. of our pets. My dogs loved it so much they overate it at first but now after a few months they "self regulate" the amount they eat and as senior Great Danes (both almost 10) with arthritis, they are getting around better, weight is perfect and coats look shiny. great product.

Rated 5 out of 5 by from The ONLY dog food w/ charcoal brisket sized nugget 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….
