Additional information (Wiki): Corgis are herding dogs and perform their duties by nipping at the heels of the animals being herded; the dog's low stature allows him to avoid being kicked in the process. The Cardigan Welsh Corgi and the Pembroke Welsh Corgi were interbred until 1934 when the American Kennel Club then recognized them as two distinct and separate breeds. Welsh folklore says the Corgi is the preferred mount of fairy warriors.

The Cardigan is one of the oldest breeds of dog in Britain and has been employed for centuries by Welsh farmers to herd cattle. He is the larger of the two breeds with large rounded ears and a foxy, flowing tail of moderate length set in line with the body. The Cardigan is allowed more colors than the Pembroke, though white should not predominate. His coat is short or medium in length, hard textured, and weatherproof with a good undercoat. He stands about 12" at the shoulder and weighs in at approximately 30 lbs. The Cardigan is sturdy, tough, mobile, alert, active, intelligent, steady, and neither shy nor aggressive. He is snappy and prone to nip heels and not recommended as a pet for children

The Pembroke is believed to have been introduced to Wales by Flemish weavers about 1100 while 920 is also a suggested date. The breed features pointed ears and is somewhat smaller in stature than the Cardigan. She is considered a practical little dog, low-set, strong and sturdy with sufficient stamina to work a day on the farm, but friendly and out-going as well. Her head is fox-like and the tail short. The Pembroke is less apt to nip at human heels but is not recommended for young children. Historically, the Pembroke was a breed with a natural bob tail (a very short tail), and today, if the Pembroke has a tail at all, it is usually curly. Due to the advent of tail docking in dogs, the bob tail was not aggressively pursued, with breeders focusing instead on other characteristics, and the tail artificially shortened if need be. Given that some countries now ban docking, breeders are again attempting to select dogs with the genes for natural bob tails. Pembrokes stand 10 to 12 inches and weigh approximately 30 lbs.
