When Your Dog Reacts to Protein — Any Protein.

Some dogs' immune systems react to proteins in food, triggering skin flare-ups, digestive upset, or both — and identifying the exact culprit can take months of elimination dieting. Hill's® Diet z/d® takes a different approach: instead of switching to a novel protein, the proteins in z/d® are hydrolyzed (broken down to a microscopic size) so the immune system simply doesn't recognize them as something to react to.

This makes z/d® one of the most definitive options for managing food sensitivities and a key tool in food allergy diagnosis.

How It Works

• Hydrolyzed Protein System — proteins broken down to minimize immune recognition
• No intact animal protein — removes the most common food allergens entirely
• Highly digestible carbohydrates and fats — reduces GI workload
• Manages both dermatological and gastrointestinal signs of food sensitivity
