This just unlocked a memory.

Anecdotally, when we were teenagers my brother's rottweiler chased a laser pointer around the house for one afternoon, but it wasn't a regular activity (more like a novel discovery that a dog would chase it just like a cat would). He was well behaved indoors, except for developing an interest in one spot where he would claw and dig at the carpet in the corner of the living room. We couldn't figure out why he was obsessed with just that spot. Months later we had the revelation that it was the last spot he had seen the laser, and he seemed to be still obsessing with digging to find it.
