Teeth grinding in stall
I've had my appendix mare for almost a year now but she's recently become extremely moody in her stall and in the cross ties. She has been constantly grinding her teeth and pinning her ears, especially if the horse beside her puts his head out of his stall or if another horse walks by. Even when she's in the cross ties and none of the other horses can get near her she grinds her teeth if they even look at her. Because of the weather she has been unable to go out regularly but I have been riding her every day so she has a chance to stretch her legs. And ideas about how I can get her to stop?
