I bought this for my eight year old greyhound (as well as the arthritis tonic) when I noticed he was a little grizzly on cold days, and pulling up sore after exercise.
It's great value for one thing, and goes down no worries sprinkled over Dave's breakfast.
He's been a bouncy, happy dog since he started on it a few weeks ago, with a super shiny coat and no signs of stiffness at all.
Very happy with the result!
