"This has been a great replacement of a more expensive chew sold to me by my vet. My dog is only 15 months old, so to have been diagnosed with Hip dysplasia so young was very disheartening. The previous vet chews were expensive and didn't seem to make a huge difference. After going through the first 90 chews and still no change, I decided to do some research and when I found these, it fit all the guidelines that I'd found in my research at a much more reasonable price."
