More: Shelby is a ball-obsessed lab that falls asleep with the ball in her and would play fetch nonstop if she could! There is nothing better then leaping in the water to retrieve something return to and repeat! Luna has been with me for only 2 weeks, she is a rescue and is 4 years old. She has been the perfect girl and also loves to retrieve. Unlike Shelby, she will bring back anything you throw. She is also a diver and and will grab anything off the bottom creek.
