Royal Canin Veterinary Diet Hydrolyzed Protein Canine Treats are part of a comprehensive line of veterinary-exclusive formulas for dogs with food sensitivities. These dog treats are made with hydrolyzed soy proteins composed of low molecular weight peptides. That means the digestive tract can absorb these proteins, reducing the risk of a reaction in the immune system. Optimal amounts of B vitamins and amino acids support a healthy skin barrier. And with Relative Supersaturation (RSS) methodology, these treats help maintain a healthy urinary environment. They're a perfect way to reward dogs during an elimination diet trial or those with long-term food sensitivities.
