Patterdale Terrier

The origins of the breed can be traced back to the cross breeding of The Old English Terrier (the original black terrier) and the Northumberland Pit Terrier (now extinct) and later to the Lake District, specifically to Ullswater Hunt master Joe Bowman, an early Border Terrier breeder. where he used the best Red Fell terriers and the best local hunting terriers available to him, so that he could continue his efforts to refine the breed even further. The breed did not gain notability until Cyril Breay, a schoolmaster and huntsman, refined them even further, using the best dogs of northern England. It is believed that all current Patterdale Terriers descend from dogs bred by Breay. Wikipedia
