Squirrels, cars, cats—now you can add laser pointer beams to the things dogs love to chase. But why do they so doggedly pursue the litte red dots these office tools project onto walls and floors? Seems the flighty motion triggers the predatory hunter in them. Dogs will chase laser lights endlessly, which might be fun for humans to watch, but is eventually really frustrating for them if they don’t come up with some reward for their efforts. A good way to have laser pointer fun with them is to hide treats in corners and under tables and let the laser pointer fall on those items during your play.
