Fantastic food!

Since switching from a OVERLY popular certain commercial diet, my girl has had the best skin. ONE mild ear inflammation, and a small hot spot in 5 years, vs several a month with the old food. Worth the money!

Exactly what was needed...

My baby, Zoe, suffered from very loose and bloody stools when I got her at 12 weeks old. I could tell that she was also having discomfort and stomach cramps. My veterinarian prescribed Royal Canine Hydrolyzed dry dog food. We saw immediate results. Zoe is now approaching her 1 year birthday and we are starting to phase in Royal Canine Adult Yorkshire Terrier dry dog food. I am thankful that you offer specialized products for our fur-babies.

Food Allergy Relief

I started feeding my dog Royal Canin Hydrolyzed Protien last year on recommendation from her vet. She initially presented with a snout that she rubbed raw and an inflamed bum with frequent diarrhea. The vet concluded that she was experiencing food allergies and that the hydrolized protein might work for her and be easily digested. We switched to the Hydrolyzed Protien and she no longer has any itchiness or diarrhea - Royal Canin for the win!
