Our review of Hill's Prescription Diet d/d Potato & Duck Formula finds it best suited for dogs with suspected food sensitivities who need a single animal protein and limited ingredient diet.

• Free from soy protein: Excludes soy protein to help avoid a common allergen and reduce the risk of adverse reactions.
• Supports skin health: Nutrients included to help maintain a healthy skin barrier, which can reduce itching and scratching tied to sensitivities.
• Veterinary formulation: Developed by Hills nutritionists and veterinarians and intended for use under veterinary consultation.
