I still think it sounds like great fun, but I recently read a post on another forum that I thought worth passing on: A behaviorist responding to the question says it's probably not good exercise for obsessive dogs. The troubled dogs she treats often need exercise, but to have them fruitlessly chase a light with no reward at the end could make their problem worse.

But, again, she only made the caution for dogs with servere behavior problems.
