I got those little tiny training treats from Petsmart and if you know Schnauzers, they are quite independent and don't want to do a lot of trick sort of thing. When I started with Daisy and Perry I would hold a little treat (that way with little treats they don't gain weight) in one hand and shake their paw then give them the treat, after a little while they understood and in the meantime they have learned to shake, lay down, crawl and sit up. Just have patience, if you scold them, they don't respond to that. Good Luck, I'm sure you can do it. Hugs to Zeke.
