I'm subbing, too!
My boy is a hard catch; we have to bribe him into a stall with some food and separate him from the other 2 horses to get him in there. His previous owners would use more than one person and then corner him, trapping him with a rope, and then catch him. So I have that to undo.
So far I've caught him, grained him while I had him in hand, and then just brushed and walked around with him, letting him eat the lush grass outside of his pasture. We exposed him once to the hose and he enjoyed it. Then I turned him out. So far, still hard to catch... I know it's going to take a while but I hate having to make him feel cornered again in the stall. (I always talk to him, and stand stroking him for a moment before I halter him.)
