What is it about Border Collies and Frisbees?
One is a descendent of droving and gathering breeds from the Welsh-English and Sottish-English border regions whose origins can be pinpointed to a single dog, Old Hemp, who was bred in Northumbria in the late 1800s.
The other is a flying plastic disc developed in the late 1950s by a company called Wham-O.
