I don't know why my puppy has a problem with my hand signal for stay, but for some reason, whenever I hold the flat of my palm out to say "stay" He'll jump and start yapping at it and try to jump up an grab it. Sometimes he curls his lip, barks or snaps at it, usually he seems to just want to play with my hand so I'm thinking maybe it's just cause my hands are associated with playing with him. I've never hit him with my hand of anything and even my ex-roommate who would chase him around and scare him never hit him...at least not hard enough to hurt him, as far as I know. So anyways, as soon as I hold my hand to do that stay command, he'll jump from sitting position and get real hyper, even before I vocalize stay. What do you suggest I do about this?
