how do you teach them to do tricks? i can get whiskey to sit and stay only if i give her a treat but i just taught her that so she wouldn't be jumping up on everybody-i'm scared she'll get arthritis or something when she's older if she stands up too much on her hind legs. i've never had a yorkie before and after reading all that stuff about hip and knees going bad i worry. how do you make them roll over and play dead and shake hands and stuff???
