Just what our Great Dane puppy Wonder needed!

We were feeding our Dane a holistic brand and she wasn’t have regular bowel movements and they didn’t seem solid. Our vet recommened Royal Canin and we will NEVER choose another brand. She is growing right on track, very active, regular bowels and her coat is beautiful! Every large breed owner should consider buying this food.

My Mastiff LOVES this stuff!

[This review was collected as part of a promotion.] Tried my English Mastiff puppy on several giant breed puppy diets and he prefers this one by far. Super palatable, no stomach upset and doesn’t make him have horrible gas like some of the others we tried.

Great Puppy food

[This review was collected as part of a promotion.] I have a Husky and he was so sensitive to anything else. My vet recommended Royal Canine and my Husky loves it!!! His tummy loves it. He’s happy and very healthy and I won’t purchase anything else. He’s now 4 months old and such a happy boy. Looks forward to breakfast and dinner lol. I have a Pomeranian as well he he won’t eat hard food other then Royal Canine. He was a wet food only dog. We purchased the puppy food for Apollo and had to try the small dog formula on Jake and he’s in love. He’s almost 4 and a very picky eater. He absolutely loves your brand. I posted a picture of both of my babies.

Love the breed specific food

[This review was collected as part of a promotion.] I wanted a quality food for my St. Bernard puppy. We were feeding her iVet large breed puppy, but neither that nor Science Diet seemed like the best food for her. Love how you have formulated not only the puppy, but the junior as well for giant breeds. Thank you!!
