[Chihuahuas] Luxating Patellae

[SUSIEWHO48]

My oversized Chi has  l.p. has thrown it out a  few times but is still gong 
strong w/o surgery. I've tried to keep his weight  down to avoid stress on 
his leg and we don't take real long walks. So far so  good..he's going on 12 
yrs old. When he walks he's out of alignment (that's what  we call it) his 
back rear left leg is  askew.
