Helps joint pain

My 9 yr. old 85# Doberman was scheduled for surgery if she wasn't improved after a couple of months. I started giving her Purina One Plus Joint Health Formula and the surgery was cancelled. Of course she was on restricted activity too. I was having difficulty finding this dog food and was happy when I found it on Chewy. Very happy that I can continue to feed her this food.

Our our Boston terrier Dagger has been eating Blue Buffalo for years. Dagger is entering middle age and my daughter suggested Purina. She works for a pet hospital and they highly recommend it. Dagger absolutely loves the taste he is enjoying his new food and it's healthier for him and his joints. You really should try it

My dog is 8 years old and has hip issues. This food helps keep him on his feet along with hip and joint supplements.

My dog loves it

She loves the taste and the fishy smell. Hard for me to get past the smell since I hate seafood but my dog loves it.

Tender Dog food

Every other bag I get a good one with large tender pieces in the bags. It's weird, I wish I could get the large tender pieces every time.
