I wore a fanny pack loaded with sugar cubes or horse cookies, whatever I had handy. Tickled his upper lip with my fingers and when he even remotely lifted his upper lip, I gave him a treat. I only worked on it for a few minutes a couple of times a week and it took me about 3 weeks. If I had of tried harder, worked longer, it wouldn't have taken nearly as long. Probably could have taught him in one day, but they get bored quickly.
They'll sell their souls for a treat won't they:)
