Hey Instructables! My dog, Coco, loves chasing lasers, and now he can always have one to chase! I mounted this laser on two peices of hockey tape that were stuck together. The button is pressed down by a peice of tape. Wherever he looks, the laser follows! He also looks a bit like a robot! He is a little weirded out by the strap around his head, but he will chase it for short periods of time. I think that this would work better on a cat, since they seem to enjoy chasing lasers more, at least from my experiences. It might also work better if the laser was mounted on the animals collar, so as not to bother them. If you like the idea, please vote for me in the Wicked Lasers Contest! Thanks!
