Thanks, Steph and Harlyjo.
He'd always try to beat on one of my Aussies.
We'd play this game every morning when I went out to do chores. He'd meet me at the door. I'd stomp at him like I was going to get him and say "GRIFFIN" really gruffly. He'd jump up and dance on his hind legs, then jump in front of me, not touching me with his paws. I'm gonna miss the little stinker.
