Lameness (equine) Lameness is an abnormal gait or stance of an animal that is the result of dysfunction of the locomotor system. In the horse, it is most commonly caused by pain, but can be due to neurologic or mechanical dysfunction. Lameness is a common veterinary problem in racehorses, sport horses, and pleasure horses.
I've heard 'bridle lameness' used as a short hand for 'horse doesn't want to work' (as in not lame in legs/back, just lazy). But I'm sure it has other meanings too. It sounds as though your horse is uncomfortable somewhere OP. had her out 6 times in total until he was better. I am now concerned that his back is bad again. Do you think it could be he back, or could it be something to do with his bridle/bridle lameness. He has a comfort bridle with padding around the nose and poll, and has a loose ring snaffle with a losenge.
