The Welsh Corgi or Corgi, plural Corgis, or occasionally the etymologically consistent Corgwn;
is a small type of herding dog that originated in Wales. The name corgi is derived from the
Welsh words cor and ci (which is mutated to gi), meaning "dwarf" and "dog", respectively.
Two separate breeds are recognized: the Pembroke Welsh Corgi and the Cardigan Welsh Corgi. Physical
differences are seen between the two breeds. According to the breed standards, overall the Cardigan is
larger, both in weight and height. Their tails are of different shapes, and docking was previously performed
on Corgis before the practice was largely banned.
Historically, the Pembroke has been attributed to the influx of dogs alongside Flemish weavers from around
the 14th century, while the Cardigan is attributed to the dogs brought with Norse settlers, in particular a
common ancestor of the Swedish Vallhund.
