Once upon a time there was a funny looking dog named Lucy. She was low to the ground and a meter long, and had reddish-golden-brown fur. She was very unique in appearance.
But she decided to do something to make herself even more noticeable, so she swallowed a basketball. And there she was - a skinny front end, a skinny back end, and a basketball in the middle.
At least, that's what I think happened. Because there's no pups coming out of there, and if the belly gets any bigger it will go POP.
Her appetite is still - ahem - VERY healthy, her temperature is stable, and she shows no signs of impending birth.
Except for that basketball in her belly.
