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 Prescription 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 their 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).

Great food

My dog loves it! Seems to also really be helping with her coat too because she is so soft and doesn’t itch anymore. Less itching means less shedding too so that’s a plus. She also has so much energy for being a senior dog now so I’m happy with this food. It’s expensive but I feel like you get what you pay for and I want to invest in my dogs health so overall I recommend!

Good but way overpriced

I get that we “get what you pay for”, but the price of this bag is ridiculous, likely bc they make it by RX only. I have older dogs and have to mix this with other food to account for other issues, so feeding two dogs for a month costs $150. If I didn’t need the joint and kidney support, I wouldn’t even look at this product and would go with a high quality natural food that is lower in cost

Saved my pup

My dog loves this food and two and a half years ago her vet said she had two years to live. My girl is doing FANTASTIC! Thank you Hills.

jury is still out! Next blood work, etc. not for a month.

Dog just diagnosed with kidney disease 4 months ago. He seems stable and likes the food. He's only 11 pounds and I wish they made 'small bites'; these are a little big but work well with warm water added. NOT helping joint problems so far.

My Dog Loves the Flavor

Our dog was diagnosed with kidney issues over 2 years ago, based on her blood work. We were told to get this for her. They are small bites and she likes it with peanut butter mixed in. We also give her cooked hamburg and chicken along with this food as a variety. Seems to be working, she is now 16 and in great condition.

My dog Likes this dog food

Obviously, I buy this because my dog has kidney failure. There are four options I’ve been able to find on the market. This is the only one that she will consistently eat.

The product is good

The product is good unlike a very unreasonable shipping time. I left an honest review but Amazon blocks the truth. I had to chat three times with them and had a phone call about shipment specification as it was one thing and then it took them two weeks to ship it and they kept denying it. Use chewy to order. Save your time and money.
