“There is a strong reverse psychology component operating in the premack principle as well. The more you tell the dog to do what he wants, the less he wants to do it! Therefore, not only have you patterned the dog to pay attention to you as part of his going away and sniffing, but sniffing is no longer the big deal that it once was because there's no conflict. Nobody is telling the dog it's not allowed.
In fact, I keep telling the dog to go away from me, and the more I do it, the more he starts wanting to re-engage with me. "But wait, I wasn't done staring
at you yet!”
