UK scientists are currently working on a dog food additive which will make their poo glow in the dark. The idea is to help shortsighted people and others to avoid the traumatic experience of stepping in it at night.
In a random survey a Mr P.Golightly of Great Twittering said "It will be a godsend. Only the other night I went into my garden to get some washing in for the wife, and I trod in a packet left by my rotweiller. I slipped and fell down twelve stone steps and hurt my arm. It didn't do the washing much good either. If I had seen it I would have been ok."
Apparently the makers of Whinealot dog food have given their thumbs up to the idea, along with several other makers.
