Jake knows quite a few. The fun ones are definitely Shake no, nod yes, count (with pawing the ground), spanish walk, kick a ball and bow (with both legs forward or down on one knee).
Though he also knows the two that can cause problems, the lay down and the rear. He can do everything from the ground or under saddle.
I've been trying to work on him picking things up but the farthest I have gotten is him biting whatever I'm pointing at. We are also working on hug. I'm having a hard time thinking of anything else....I refuse to teach kiss, which I consider to be a horrible trick (No teeth near my face unless if I am the one giving the kisses)
