Blue Heeler Behavior Chain - Basic Commands

Carlin my Blue Heeler (Australian Cattle Dog) practicing a behavior chain of basic commands. Instead of a clicker I use a marker word (YES!) which tells him that he is done with the behavior, is correct, is released, and is getting a reward. It's not that I don't like clickers - I do - it's that I don't think I am coordinated enough to have another object in my hand.
