Hmm Lifting the front legs high and walking...My boy is not athletic as this guy and doesn't try as hard, but he does it well enough for me.
Well Its more of a cheap trick but I taught him to paw by tying a rope to his pastern, poking him in the lower shoulder (his cue) lifting it up, treat....after about 20 tries he started doing it on his own. Then I would teach him to stop as soon as I removed the pressure, so lets say I could say 2+1=? Then poke him till he pawed three times then stop...its all for show and the little kids love it. They also love asking him yes/no questions. The trick is to make the cues subtle enough. ;)
I eventually was going to start some trick tutorials...maybe I'll get started on that.
