@EdVonSchleck Odin wears a halter (sometimes called a "gentle leader") because his fur is so thick that if you attach a leash to his neck, he doesn't feel it at all, and is completely unaware of what you're trying to signal to him. It was a nightmare to walk him until we switched to the halter when he was six months old; he feels a gentle tug on his chin and he understands clearly which way we're turning or that we want him to stop. It was an immediate dramatic improvement, because he wasn't being difficult and disobedient on purpose.

He found the straps annoying for the first few weeks, but soon no longer thought about them at all. It doesn't prevent him from eating, drinking or otherwise using his mouth freely. (You can't see them in most photos, but there are straps that go around the back of his head as well as his nose.)
