Jezzy rarely barks, but if her ball rolls under the TV stand, she'll bark for us to get for her. It's not that she can't get it herself; she's small enough to get under there. I think she's claustrophobic, which, if you know anything about the origins of Yorkies, is totally ironic. They were bred small back in England to be ratters; some thought they were better than cats. Yet my dog doesn't like getting in tight spaces. Sigh.
