Pembroke Welsh Corgis are active, alert, and intelligent dogs, which in addition to their lower stature made them useful as a herding and cattle driving dog. Their energy level requires physical and mental stimulation in the family environment, which can be met through participation in dog sports such as flyball, musical freestyle, herding, Frisbee, agility, tracking, and obedience as sport. Pembroke Welsh Corgis also bond with people as animal-assisted therapy dogs. Their reputation as a good family dog means they can be around children; however, as with all dogs, extremely close supervision is needed to prevent accidental injury to the child or dog and avoid the dog's subsequently developing fear-based defensive aggression.
The Pembroke Welsh Corgi was created in Pembrokeshire, Wales for the purpose of herding cattle. This breed is believed to have originated from the Swedish Vallhund dogs that were brought to Wales with the Vikings, although the breed may have been introduced into Wales by Flemish weavers in the twelfth century. Others feel that the breed's ancestor is the Cardigan Welsh Corgi, which was brought to Wales by the Celts in 1200 BC. The Pembroke Welsh Corgi is the smallest dog in the herding class and the name "corgi" is often translated as "dwarf dog." The Pembroke Welsh Corgis are very adept at herding, despite their small size, and because of that reputation they have enjoyed immense popularity. The breed found its way to America in the 1930's. Until that period, the Pembroke Welsh Corgi was cross-bred with the Cardigan Welsh Corgi, which accounts for the similarities between these two breeds. In 1934 the Pembroke Welsh Corgi appeared in America and was recognized by the American Kennel Club that same year. The dog's popularity exploded in Britain and beyond when it became the favorite pet of both King George VI and Queen Elizabeth II.
