LOL... funny, but TRUE!! He was on a powder form of glucosmine that I just sprinkled on his food, I think it was GLC 1000. Yes, he had arthritis very bad in his hips and knees... we had stem cell therapy done with him in March 2011 and he was doing awesome during those next few months -- puppy energy and playfulness. I am not sure of the severity, but his knee cap was always popping out and we could easily move it around. His first ACL was November 2008 and it had to be done again (same knee) in February 2009.... the line that was used snapped, it was too thin. Nitschke recovered very quick both times, but we still had him on limited activity for over 4 months.
Let me know if you have any other questions or want to chat about it
