Three types of curs are referred to in ancient Welsh laws, the watch cur, the house cur and the shepherd's or herdsman's cur. Which ever connotation you choose to adopt, today the word corgi is generally used when referring to both types of the small cattle dog. While similar, Cardigan and Pembroke Welsh Corgis come from different origins. The Pem's ears are erect, firm and of medium size tapering slightly to a rounded point. Cardigan's ears are larger and more rounded.
Cardigans are bigger, longer in body, and taller at the shoulders.
Pems have short legs with forearms turned slightly inward. The Cardigan's front is similar to a Dachshund or Basset with bowed legs and toes that point outward. Getting to know you. Corgis were recognized as purebred dogs in Britain in the 1920's. In 1934 the Pembrokeshire and Cardiganshire were recognized as separate breeds by the English Kennel Club.
