Cynologists believe that that the progenitor of all long-legged terrier breeds was the now extinct Old English Terrier. This branch of the family tree were diggers who worked in the soil, and with few exceptions, had narrow fronts and straight legs placed fairly close together so that when digging, loose dirt would fly between their spread rear legs. The ears of these dogs were also natural and dropped over to prevent flying dirty from entering their ear canals. Form follows function! Did we mention that they were/are diggers?
