The Welsh Corgi, sometimes known as just a Corgi (/ˈkɔːrɡi/, Welsh for "dwarf dog"; plural "Corgis" or occasionally the etymologically consistent "Corgwn"; /ˈkɔːrɡuːn/), is a small type of herding dog that originated in Wales, United Kingdom. Two separate breeds are recognized: the Pembroke Welsh Corgi and the Cardigan Welsh Corgi.
In 1925 the first Welsh Corgi was bred
. Historically, the Pembroke has been attributed to the influx of dogs alongside Flemish weavers from around the 10th century, while the Cardigan is attributed to the dogs brought with Norse settlers, in particular a common ancestor of the Swedish Vallhund. A certain degree of interbreeding between the two types has been suggested to explain the similarities between the two.
