More: Shelby is a very active dog and loves to steal my gloves out of my back pocket. She also likes to steal any towels or rags that are within her reach. Tennis balls don't have a chance as she will puncture them within an hour . She loves to ride in the truck and if she has any thought that I am going somewhere she will jump in the truck and stay there. You could throw the ball all day for her as she has so much energy. She is like the Energizer Bunny she keeps going and going.
