Did your veterinarian recommend a therapeutic diet for your canine companion? PetSmart has exactly what you need to help support your pet. Your dog’s nutritional needs are as unique as they are. That’s why your vet may recommend a special diet that is tailored to support your pup’s health requirements, such as:
  1.  Urinary Health
  2.  Kidney Health
  3.  Allergies
  4.  Digestive Care
  5.  Gastrointestinal Health
  6.  Sensitive Skin
  7.  Weight Management
  8.  And More
Because these special diets are intended only for pets with specific health conditions, your vet must authorize the food before you purchase it. Visit your vet to learn more about switching your dog to a therapeutic diet and how to make the change. Always follow your veterinarian's advice when transitioning your dog to a new food plan. If you have any questions or concerns during the transition, consult your vet.
After talking with your vet and getting their authorization for a specific therapeutic diet, you can find everything your dog needs at PetSmart. PetSmart carries a wide variety of vet-authorized diets in different flavors, sizes, and both wet and dry formulas, so you’re sure to find the one your vet recommends and your furry friend loves. And, with PetSmart’s convenient store locations, easy online ordering, and Autoship options, getting your pup the vet-authorized food they need when they need it is simple.
While you’re getting your dog their vet-authorized food, why not also pick up some yummy bakery treatschewy treatstraining treatsjerky treats, or dental treats? Looking for a different type of dog food?
