He has had one twisted front leg since he was young (we don’t know if he was born that way or if he had been hit by car before the shelter got him). Our concern has been that his mobility be protected as much as possible so we have had him on the 3mg twice daily soft chewables for over 5 years now & he has not slowed down. He shows no joint issues even with that twisted front little leg. – Natalie G., Santa Clarita, CA
