I bought a lurcher sappling for next to nothing from a traveller in a pub at Appleby. He had acquired it as part of a deal for a horse and wanted rid. He said he didn't know anything about it, not even if it was stock broken.
You would think all the warning signs were there but foolishly I bought it anyway. I guess I felt sorry for it. It looked so miserable tied up outside the pub.
Anyway, turned out to be a very decent dog with no vices except it was not interested in rabbits, only bigger game.
Stupidity sometimes goes unpunished. But not often.
