The Pembroke Welsh Corgi (/ˈkɔːrɡi/ or Corgi, plural Corgis, or occasionally the etymologically consistent Corgwn; /ˈkɔːrɡuːn/) 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. 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.
