"Updating my review to say I just ordered a second jar of these. I give both of my dogs one Active Chew and some unflavored gelatin everyday to protect their joints. My one dog who had FHO surgery & has hip dysplasia is doing so well that I've been able to take him off of his NSAIDs. Our vet is pleasantly surprised at his range of motion with the hip dysplasia compared to what his X-rays would suggest he would be capable of. I'm not saying this supplement is the holy grail, but combined with appropriate exercise, keeping him lean, and adding the gelatin it is definitely working for us."
