Thank you to the contributor who sent in the above title and the following photos of Issy (Isabel) M and Tinker of Parwich, taken at the Mountain Rescue Demonstration Team at Longshaw Sheep Dog Trials on Saturday 30/8/08. These Sheep Dog trials are said to be the oldest in the country, having been run continuously (apart from the two World Wars) since 1898.

Surely Tinker, splendid dog though he is, can not have been found guilty of being a sheepdog.
