I'm at the park with Annie twice a day. Early in the morning (sunrise) and again in the afternoon. Having her run for two to three hours a day keeps her happy and my house in one piece. German Shepherds are known to be great family pets. Watching Annie play with small children is proof of that. When kids come up to her, she will always give them her tennis ball to throw. She never jumps or barks at them, she just waits. I'm sure she knows they can only throw it so far so it's an easy catch. I have to carry two tennis balls, since she won't let the first one go until I throw the second one. Something else I see at the park is a couple of teenagers who pitch a tent at the park. Great why to block the wind, not have dogs jumping all over you and have a little privacy. Wonder if their parents know what they are doing with their pop up tent?
