Sarge did this while he was "puppy biting" while we were playing and he got all riled up. When we're playing and I have to go do something else he chomp down on my pants and gets dragged (not literally) behind me. I used clap my hands loudly if he was nipping and say "That's Enough". It startles him enough to know its not exceptable. And now when we're finished playing i only have to say "that's enough" and he'll stop.
