Hill’s Prescription Diet z/d is a dog food made for pets with food allergies. It uses hydrolyzed protein to avoid common allergens. This means the proteins are broken down into small pieces that don’t trigger allergic reactions. Furthermore, Hill’s z/d also supports skin and digestive health with added vitamins and minerals.

It has lots of fatty acids, which help keep a dog’s coat healthy. But since it’s a special diet, a vet should recommend it. It’s made to be easy to digest and supports a healthy gut. Plus, it helps prevent bladder stones with its S+OXSHIELD.

Always talk to a vet before changing your dog’s food, especially for health issues like allergies.
