This is anecdotal but when I see animals that play with laser pointers they seem very... Neurotic. Little dogs especially because they don't get any exercise so they fixate on laser pointers. And since laser pointers don't provide a physical outlet of energy they just go completely insane... The gal needs to walk that little dog at least an hour a day.. Well all dogs should be walked at least an hour. Poor dog. That's why you see so many aggressive/neurotic little dogs more often than larger ones. :<
