Often times when I am grooming or taking up my horse, he turns his hip into me and gets that 'angry wrinkle' under his eye. I have been thinking it is an impatient habit that he does to tell me he just wants to be done, but obviously it is unacceptable behavior. Since he is tied up when this happens I don't have the rope to re-correct him immediately so I end up resorting to untying him and proceeding with groundwork. After I have changed his attitude, I can usually finish tacking him up.
I would like some help with completely correcting this problem, its a drag not to be able to simply brush, tack up, and go. Thanks for the help!
