mine picks and chooses when to jump up, sometimes she does it no problem first try, other's she doesnt try at all just paws at the edge of the bed (of course at 2 AM lol) and others she'll jump forty times to make it and will back away and not let me grab her if i try to help her, guess sometimes she's very determined and others she's VERY lazy. I've been told though that yorkies are known for having really bad knees and they shouldnt be allowed to jump very much at all, but it's really hard to stop her |
