When the horse has either a temporary or permanent injuty
I always thought of it like a sprained or twisted ankle
Lame means sore or unsound, if a horse is lame it means they are hurting and unable to continue their work.
A horse is lame when their gait at the trot or walk is off. You can tell becaseu the horse will pump it's head up and down and will look off
Exactly was Tecla said... it's basically when a horse is limping or can't move properly.
It's when a horse doesn't move properly because he's in pain somewhere in his body and it affects the way he walks, trots and/or canter.
