Twelve-year-old Erin Morris is thrilled when she is asked to train Blue, her grandmother's black Lab, for a dog show. There is just one problem -- Blue is perfect, but Erin isn't.

Also, Erin is tall for her age and she keeps tripping over her own feet, so she's sure she'll hurt Blue's chances of winning. That's when her friend Cassie suggests a "reinvention."
