Abstract: The present invention is a device used to deter horses from biting handlers and/or equipment when the horse is being groomed, bathed, walked or worked with in any way and to otherwise amuse the horse when left unattended. The device preferably consists of a curved elongated elastomer bar with ridges that attaches to the horse's halter with webbing and snaps. When the device is attached to the halter within easy reach of the horse's mouth, the horse is able to nibble at, chew on and bite on the elongated elastomer bar. This device provides an outlet for the horse's natural urge to chew and bite and helps to prevent the horse from biting handlers and/or chewing on equipment.
