Pembroke and Cardigan Welsh Corgis

Originating in Wales the Welsh Corgi is classified as a small herding dog. There are two distinct breeds which are recognized: the Cardigan Welsh Corgi and the Pembroke Welsh Corgi - the latter being the most common. Each are named after the county in Wales where it originated.
Corgis perform their herding duties by nipping at the heels; the dogs low height allows it to avoid being kicked in the process. Corgis drive livestock differently than other herding breeds. Instead of gathering the cattle by running around the livestock, corgis drive the herd forward by nipping at their heels and working them from behind in semicircles. Rarely giving ground, should an animal turn and charge, the corgi will bite its nose, causing it to turn and rejoin the herd. Corgis are used for herding cattle, sheep, Welsh Ponies and are also able to herd geese.
The similarities between the two breeds include erect ears, foxy head, long, low body, intelligent, energetic, ability to herd and act as guard dog.
The physical differences between the two breeds include bone structure, body length, and size. Cardigans being larger and more heavily boned than the Pembroke, have large rounded ears and a 12-inch-long foxy, full length tail. A Pembroke has a natural bob or docked tail and the ears are erect, firm, and of medium size, tapering slightly to a rounded point. The Cardigans ears are more rounded at the tips.
