And she may have a point

!
I had a Westie who went absolutely neurotic over the light. She'd chew walls to get at it. One night, my hubby ran the light under the pillows on the couch. Woofie didn't tear up the pillows, but she waited, tense as a clockspring for an hour for it to "come out" again. Then we shut off the lights and went to bed, she reluctantly joined us. The next morning, the first thing she did before even going potty, was to jump back on the couch and resume the position
So, whereas the dogs will chase everything from flashlights to laser dots, we don't do it often or for long.
They DO like it though, don't they?
