Got one of jeffs newest pups as a pet not the same reasons you guys get them. I agree the line cannot be traced to the 1200s, I think he has twisted this as the first recorded use of the word Lurcher in English is from the 1200s, it came from the french word lerce which meant sneaky/lurker. Of course these dogs have been around forever,there is even a roman mosaic of a lurcher in the british museum.
Regardless, he breeds lovely looking dogs, and is very eccentric lol
