He is not afraid of it. In fact, he loves the hose. But he reacts in the same way as if I touch my finger to his side - steps quietly away from the pressure. If I spray him, he steps quietly away until he's against the fence and can't go any farther. Once he's at the fence, he stands still.
How can I teach him to NOT move away from it? I've seen lots of advice for dealing with horses who are afraid of being sprayed - but what about the ones who are just doing what they think they're supposed to be doing: moving away from pressure? How can I stop that so I don't have to rely on a fence to spray him (or do continuous circles)?
