Great Food

My Dog was having issues with his bladder because of the previous dog food he was on. I started him on the Royal canine food and his issues resolved. He has been so much healthier and happier since he started this food.

Not for All Dogs

I've heard it was a good food for dogs, but our dog doesn't like it without putting some moist food and water to make gravy in it.

Newfie loves it, Pyrenees allergic

This food is amazing quality! We recently made the switch for both our newf and great pyr (giant breed was not available at the moment) and they both love it! However, shortly after Franklin, our Pyr started licking his paws, biting at his pads and tail and shaking his head. Needless to say, Ben will get all the royal canin while Franklin is on a food venture

Results speak for themselves

I have been feeding Royal Canin for a year now with amazing results. I previously looked down on this brand because of the ingredients and was feeding my dogs boutique, grain-free food. Both of my dogs (one very small, one very large) are doing 110% better on their Royal Canin diets. Great coats, weight, and muscle tone. My Pyrenees mix is not picky but LOVES this food. The pieces are pretty big, but she doesn't seem to mind. She has an extremely sensitive stomach that I have been dealing with for all three years of her life and this food gives her perfect stools every time. As another bonus, her shedding (if you have a Pyrenees I needn't say more) is much more manageable because her coat is so much healthier. I highly recommend to all owners of large breeds.
