I have heard that about the shadows, but I donāt get that. What does that mean? I do understand why some would say itās cruel, but I (at least for Chase) donāt think it is. I have a cat that I do think gets frustrated about it. I bet watching you boxer when she was you get was cute!Some people say it's cruel and can cause issues with dogs reacting to shadows. We have always played with a laser light here. Not all my dogs chase it, but those that do love it. I find having certain parameters makes all the difference. We mostly play while I vacuum, and at a few other times. They know where the light comes from, and know when the game ends. I personally haven't had any problems.
When the boxer was younger we would play outside at night and she could run full out after it. Now it's a prance across the kitchen floor for the old lady. Two of my bulldog mixes love to play, and the other two could care less. The Aussie also isn't interested and prefers her tennis balls.
