Yeah good types them, cracking temperament, always happy and keen and fairly easy to train. And she was fast and very agile. Very good worker, but not the best, for the 3 seasons I worked her, til she went missing from my garden whilst I was at work, and some 'scrappies' went through where I lived at the time, it was a fairly rural location. Mine had a little less beddy than yours though, but not much.
Dam was collie/grey x beddy/grey sire was deer/grey x whippet/grey.
And yes they were both genuinely bred, as I knew the owners of parents and grandparents, all more than decent do
