I give treats. I don't hand out treats for something the horse is expected to do, and never during the lesson. The only time my horse gets treats is when ever whatever we were doing is over for the day. Of course he always gets my praise and a good pat, but treats only come when the whole job is done. He knows the difference between a treat and your body parts. There was a time he got pushy, so he got whacked on the lips expecting a treat, then I had baking soda on my hand, and he was trying to nip, so I held my hand flat and he tasted that stuff, man! He never tried to nip me again, and he always smells and makes sure that what it is my hand is good. Haha.
