We started using Wellytails Cartilage, Hip and Joint when we had an arthritic Cavalier King Charles Spaniel. It was very helpful. After Camilla crossed the Bridge, we stopped supplementing our younger dogs meals. Well, one of our dogs ended up with an ACL tear and had to have surgery. For months she didn't seem to perk up and I decided one day to pick up a can of the Cartilage, Hip and Joint and we started supplementing again - both dogs. What a difference it's made for her - she's like a pup...
