hmm, I think wave will be a good one! maybe if you could have your head more higher over his face, have his paw reach higher, that way he may wave better. maybe try that, I've noticed crayola waving if he couldn't keep that high lol. but doesn't follow commands well if I bend, lower my body a bit - for any trainings you should never bend your body. I always forget that... just because I want to hug him so badly!

anyway, good luck and I hope our kaige will get in!
