Lucy loves to spin on her back paws really fast when she plays with my son,, well thye really got going and she spun too close to the coffee table,,, you guessed it,, THUMP,,, she wanged the side of her head so hard she fell backwards,,, she was ok,, just a bit stunned and a bit embarrassed,,,, she went and sat on her bed refusing to look at us,,, poor thing....
