There are many types of environmental irritants that surround us and our pets each and every day including fleas, pollen and even the dust in our homes. For some dogs, these can cause a skin condition leading to excessive scratching. This is unpleasant for your dog and can also be difficult for everyone else in the family. These skin conditions can be treated simply from the right food. Hill's nutritionists and veterinarians developed Prescription Diet® Derm Defense™ clinical nutrition in chicken flavor specially formulated to help manage environmental sensitivities in dogs. This product requires a veterinary prescription.
