Which historical group is credited with bringing the ancestors of the Pembroke Welsh Corgi to Pembrokeshire around the 10th century?

Flemish weavers or Viking settlers

The ancestry of the Pembroke Welsh Corgi is typically associated with settlers arriving later than the Celts who influenced the Cardigan line. The prevailing historical accounts suggest two main origins for the Pembroke lineage: dogs brought over by Flemish weavers who settled in Pembrokeshire, or dogs accompanying Viking settlers who arrived in the area. While both theories point to continental or Nordic influences rather than purely indigenous development, they collectively establish the Pembroke lineage as being rooted in infusions from outside groups centuries after the Cardigan ancestors were established. This difference in ancestral input is key to their eventual formal separation into distinct breeds.
