That's Kellie Pickler's most recent acquisition above -- a big, brown bag of fun and drool named Chunk. But he joins a brood that could give the Sheltons a run for largest pack on the country music scene. Pickler and her husband Kyle also have two other dogs named Pixie and Moo Moo. Like the '100 Proof' singer, the dogs enjoy getting dressed up for special events. Pickler is a supporter of adopting pets from shelters, having recently hosted a dog fashion show for the Nashville Humane Association.
