Frodo LOVES to chase lights. He runs across the apartment any time a car drives by, so that he can watch the sun reflect on the opposite wall. In the car, he will stare at any light on the car ceiling, trying to get as close to it as he can. Headlights on his nighttime walks...that's a whole different story! Thankfully, Frodo's previous owners warned us of this behavior beforehand. It could have been quite a surprise the first time we took out a DVD or turned on a flashlight (two of his favorites!)
Sometimes I think it might be a little compulsive, but I try not to worry. Frodo doesn't really seem upset when he can't get to the reflection or anything like that. He just seems like he's having fun.
Does anyone else's Corgi display this same behavior?
