I have a horse that is head shy, when I got him he was blind in one eye, and has two chunks missing out of his tongue. He does take a bit, but I don't need one. If you walk up to him without a halter or a rope around his neck he shy's away when you get to his neck. When I put the halter on he is a different horse, you can do whatever you want but he shows fear. He has so much respect for humans. He is ver aggressive towards other horses when there is food around, he has to be separated during feeding time, unless you are there, then he does nothing to the horse. I don't know much about this horse, he was a freebie. He is very ride able, will do whatever you want unless there is no halter on him. I want him to be affectionate, and want to be around people.
