Mo, the ancient border collie, was having one of his talkative days. His many offspring knew this so they gathered around him tugging at his ears and his tail, begging for another of his stories.
"Tell us about when you went caving, Grandpa Mo," cried a chubby little roly poly pup who was very much like the old dog in colouring.
Mo looked at him across his big paws, stretched and drew himself up to sit proudly on his haunches.
