dogs with lights

I was walking my dog about 9:30 and we encountered a huge yellow dog with a red light around his neck. I was so shocked I didn't think to ask the dog's walker who it was for--the dog or him. The light was about the size of the little keg or brandy or whatever that St. Bernards are sometimes pictured with. It was red, not clear. I don't have a clue what that was about.

I'm really not up to writing more tonight but this keeps my promise to post each day and gives you something to ponder--dogs with lights, what's next? cats with windshield washers?
