It was bred down from his irish terier x line, i got the dog off another mad, cw he was young, about 18 month, he was not the best on hare, but took the odd one, thats why he was sold to me, but, he took a lot of foxes ect with me and rabbits.
His sister, cw owned and she took a lot of hares, smaller dog. cw had some good hare dogs from his lines in them days.
Sorry, i could not tell you what exact names of the dogs involved were, was just told when i bought the dog, back in 96, that it was from kings irish terrier breeding and a coursing greyhound was involved.
