I have been giving my dog glucosamine chondroitant and sulfur for the last four years for hip displacia he has had since he was born. Last winter he seemed to have had cracking bones more often then the last couple of years. Is there something stronger, and still safe for him or any exercise that would help him from getting so stiff? He is a large great Pyrenese.
Have you tried any anti-inflammatories such as rimadyl. You should talk to your vet about this. It will make your pet feel better. It is safe to give with the gluc. vetcare
