Well... YOU are the boss. Not the horse. I don't tie my horses. When my very alphish (and fast to eat) qh finishes her grain she stands by the hay and politely waiting on my paint (low in pecking order) to finish her bucket (so she could come over and lick the bucket). Why? Because she knows I'm not going to tolerate any fuss around, and she'll get several bad minutes (angry voice + waiving hands or a good smack on chest, and if no desired response a manure fork on her butt) if she tries to push the paint away from the bucket. In fact once (5 years ago) was enough to teach her a lesson.
