Veterinarians know a healthy dog food when they see one. That’s why they give Hill’s™ Science Diet™ to their own dogs. When it comes to the Science Behind Happy™, they’re experts.


In an effort to make the best dog foods around, we use high-quality protein including real chicken, lamb or salmon as the first ingredient in our dry dog foods. They’re made with natural ingredients plus vitamins, minerals and amino acids. In addition, they provide clinically proven antioxidant benefits.


Our pet nutritionists work to create every product with the best dog food standards in mind to give your dog more moments of overwhelming happiness that come from being the healthiest he can be.


Our Science Diet foods are made in the U.S. with ingredients from North America, Europe and New Zealand. It’s all part of our desire to make the best dog food available to ensure your dog is as healthy and happy as he can possibly be.
