My NSH likes to bite and nip when you 1) halter 2) bridle 3) clean his front feet (nips you in the back or the butt!). In other words, anytime you are near her face she likes to nip and bite. Usually it's nipping, but once in awhile she gets ahold of you and it's a nice pinch. How do you train a horse not to nip and bite? She's very mouthy and her former owner said she always has been. She's busy with a bit in her mouth too, usually gnawing on it. Any HUMANE suggestions? And no, I won't jab her with a tack or a nail when she does it.
