There was a time I regretted teaching Mick to crawl. Most of you probably aren't aware of how insecure he was, especially when he was young. Anyway- we were doing stays in class one night. New place for us, lots of dogs and sounds bouncing off the walls. Mick had rock solid stays, but that night it was just too much for him. By the time I got across the ring, he had crawled half way to me. BTW- that was the only time he ever did that.
Someone mentioned paw slappping. Way back when I had my first Siberian, I thought it was cute when he put his paw on my knee if he wanted something. So I taught him to do it when I said "Say please". Only problem- once he caught on, he was raking his nails down your leg if you had something he wanted.
