I've begun teaching the cue "knock" to both dogs. "Knock" will mean to hit something with your paw and make it fall over. I shaped it with both dogs tonight with a noodle box. At first Buzz was SURE it was meant to be picked up and he was SO cute trying to figure out how to pick it up. Pawing was WAY more fun though! He really got into it!
Tonight I ended when I got consistent hard, direct, paws on the object and it fell over.
Tomorrow I may start adding in the cue, or I might add distance. I haven't decided yet.
Also still figuring out a cue for Buzz. A real knocking motion is his "guess which hand" game cue combined with a "back up" cue. Thinking about a knock with right hand into the left palm. I have to see how well I can execute that cue though.
I'll try to get it on video soon. The batteries for our p&s (the camera I use for video) have decided they don't want to hold a charge, so it might be a webcam video!
