A Boarder Collie called Moss.

My father, who is 92, used to train Border Collies to International standard.
This means that a mongrel sheepdog has reached such a high standard that it is certified as International
and so it and any pups produced command a high fee.
Moss is a traditional name for Border Collies and was the last dog dad owned
he really became the village dog of Gargrave being very much recognised.
