Nice story...
And personally, I would sooner GIVE such a fellah a puppy than sell it for a few quid..
This is how things, used to be, same with ferrets, and I suppose, earth dogs as well...
WE all experience crippling damage, and accidents to our workers, and it is good to know that by placing your prefered types, in the hands of genuine guys, if, they ever, decide to keep that style of lurcher going, and, have a litter,..you only have to ask, and you are back in business again...
Anyway,..my advice, to the original thread starter, would be to , take it nice and slow,..hang on
