I don't consider spraying a horse off a ritiual. I like them clean as possible for more than one reason but I don't like putting my good wool pads on dirty horses. They brush off easier when they're cleaner.

The thing about horse show people and acting like they don't sweat is stupid. I don't and haven't shown but bet it has to do with a pretty coat of hair on the uh....show horse?

My personal horses run out and get treated like livestock. I pull my customers horses out of the sun during the day spray them off and keep their hair coat nice. When asking a premium for a animal or training I try to make things look nice. I wash my truck and trailer from time to time too though so to each his own I guess.
