You only want the best for your pup. From their bed toys and accessories to their dog food, dog treats and dental care, there isn’t anything you wouldn’t do to make sure they have the best life ever. Hill's® Science Diet® dog food offers a wide selection of foods designed for dogs of all ages and health considerations. 

For example, Hill's® Science Diet® Large Breed Puppy food is specially made with an optimal level of calcium for controlled bone growth, a unique developmental need of large breed puppies. Specialized formulas address specific needs like weight management and sensitive skin and stomachs. Some of these are grain free to address allergies to specific ingredients, as well as dog food with healthy grains like oats, brown rice and barley. Featuring high-quality protein, including real chicken, lamb or salmon, plus the vitamins, minerals and amino acids that puppies, adult and senior dogs need, Hill's® Science Diet® dog food aims to give them important nutritional support for a long and healthy life.

You are sure to find the Hill's® Science Diet® dog food and treats that you are looking for at PetSmart. Need other dog supplies while you’re here? PetSmart carries other brands of dog food that make canned dog food, dry dog food, biscuit dog treats, chewy dog treats, dog jerky and so much more.
