What is science-led nutrition?
Nutrition inspired by science — not trends — creates differences you can see, feel and trust. Our food scientists understand the combinations of nutrients and ingredients to help support lifelong health.
How much should I feed my pet?
Most Science Diet foods have a feeding guide on the package to help you determine the proper amount for your pet. It's critical to your pet's health that his or her physical condition be monitored regularly and the feeding amount adjusted as needed.
How can I tell if an unopened can or bag of cat or dog food is still good?
The datecode on our plastic bags is located on the left gusset, near the 4 or 5-digit SKU number, toward the bottom of the bag. The datecode on our medium and large bags will be located on the top of the bag, generally the front flap.
How should I store my cat or dog’s dry food?
Bags of dry Science Diet, Healthy Advantage and Prescription Diet cat or dog food should be stored in a cool, dry environment under 100°F (38°C).

My dog loves it. He has a healthy coat and has had almost no health issues. He only vomits a few times a YEAR. His digestive health is awesome.
My daughter has a dog and he never wanted to eat. His coat was excessively shedding. She finally was at her wits end and I suggested she try the same dog food we use. After all, whenever they were over her dog wanted to eat our dogs food. She was hesitant because she assumed it was too expensive. It ended up being about 25% less than the stuff she was buying.
Her dog immediately became easy to feed. He wasn't a finicky eater, he just didn't like the junk he had been getting. He now eats his full serving of food. His digestive heath is better - no more diarrhea and much less vomiting. And his coat looks better and he sheds less than he used to do. But better than that, her dogs temperament has improved. He used to be very lethargic and didn't want to play at all. He is starting to act more like a normal dog. My daughter though that he was withdrawn because he was abused as a young dog (she got him from a rescue shelter) and that is likely a part of it, but she is convinced the food played a role. She is much happier with her dog and her dog is much happier and healthier too.
