The closest I've had to a pure grey was a 3/16 bull bitch she was super fast and could turn like you wouldn't believe for a good size bitch could catch a fox like they weren't moving but in the end she packed it in, if this greyhound is no good she will be treated how you would a lurcher not just given a pass because shes coursing bred which a lot of people seem to favour when it comes to greys to breed from but always end up taking the easy option and just buying a old ex racing bitch
