Heads up! Paws down! Ears out! Colleen Lady Abigail du Fox may look like she's too refined to catch anything with her bare paws, but in fact, this pooch is a major athlete. Sue Parker says Abby loves playing with soccer balls and basketballs. "She plays very hard until, like any baby, she drops like a rock, sleeping with her squeaky cow." We'd better get Abby a caption before she falls asleep!
