A Dog's Tale

This is the rear and constantly wagging part of our much-loved collie-cross who has now been with us for 13 years. He was recently diagnosed as suffering from heart failure, but this hardly seems to have cramped his style - squirrels, white van men, the dogs who live opposite, junk mail coming through the letter box still find him standing on the settee and barking like billy-o.
We love him very much.
