Horses expect us to be predictable - it gives them confidence. I know several owners who are quite nervous around their horses and, to avoid leading a "spunky" horse to turn out, they just have gates or doors to open and their horses run out into the field or paddock. That's all okay when they are the ones caring for the horses or when they fully inform a "horse sitter" or friend who will handle their care. If a person unwittingly tries to halter and lead the horse that is used to charging out into his field on his own; disaster can occur for the person and the horse. If someone teaches their horse to pull carrots out of their pocket; rear up when they pull on the reins; walk into the house uninvited; graze when on a trail ride, etc. the horse will have a hard time if he ever gets a different owner companion who punishes the behavior. Truth is - horses need to have some basic, universal good habits (since they don't know the difference between good ones and bad ones, only what is allowed) and if you are relocating a horse, tell the new people about his background; if you get a new horse, ask about his habits and expectations. It's good communication for all.
