Some advice though, it's not smart to have them chase the lazer light because they can hurt themselves. It's also not good because they never actually 'catch' the light so they get frustrated. My first dog, Cody, I didnt know much back then and I did the lazer light thing with him and it has messed him up. He will search for lights and just FREAK out whenever he see's a shadow. I have not done that since he was young and never will.
