Back when laser pointers first came out. I went to the local County Fair and I saw a police officer with a K-9 officer, pointing a laser at the ground near the dog's feet. Wherever the police officer pointed the laser, the dog followed just as intently as any cat you've ever seen. The difference between the dog and a cat was the dog was trained to not move unless told to do so.
