Perfect for the big babies!

I am on month four of feeding my English Mastiff puppy the Royal Canin Giant Breed puppy food and I don't think I could be happier! My husband and I wanted to make sure Boudica (Boo for short) got the best start possible when we brought her home and we did a lot of research into the best options for nutrition including speaking to multiple vets and doing our own research. Royal Canin was the only brand that we could find that provided a food specifically designed for these giant puppy breeds who grow so rapidly in their first year that often times their nutritional needs can be very complex. Boo has enjoyed every bite and never gives us issues in eating all of her food. It can sometimes be nerve racking when you are feeding such large amounts of food to a puppy but having the feeding guidelines on the back have saved my sanity more than a couple of times. Every puppy visit at the vet, Boo has received a total clean bill of health and many veterinary staff have commented on her build and how healthy she looks. Thank you Royal Canin for helping to keep my big baby happy. <3

Horrible for giant breed puppies

Too much of everything! This is HORRIBLE for bone growth. Danes should not have this much proteins/calcium etc. Please fix this Royal Canin!

LOVE- I just bought an import pup.

My import puppy came over from his breeder eating this, so of course being any respectable breeder and owner as well, I followed by her wishes and continued, I am very pleased. My puppy eats so well now, instead of picking he goes head over heals for this food.

Great for my Akita pup!

I started feeding my Akita this at 10 weeks when we got him and his weight gain has been perfect! He went from being the runt of his litter to doing better than the others in terms of size, skin & cost health, energy and activity levels. I will say he is a really fussy eater, as Akitas can be, but I just mix in a bit of wet food or Salmon oil and he eats it right up!
