Pembroke Welsh Corgis have webbed feet
They were used in Wales to retrieve fowl by poor farmers who couldn't afford a more appropriate dog.
In Wales during times of collective farming PWC's were used as reverse herders. They would keep their owners livestock away from other farmers' livestock while at the same time spreading the livestock out as much as possible in order to have as much grazing land as possible. Smart little buggers
Some people believe that corgis were originally used as "fiery steeds" which fairy's rode into battle. They still carry what is known as the "fairy saddle" on their backs. (This is how Izzy got her name, with help from Grammy, Coombsie's Faerie Chariot)
Pembroke Welsh Corgis are not related to Cardigan Welsh Corgis (although before they were registered as seperate breeds there was a lot of inbreeding).Pembies come from Pomeranians, Schkipperkes, and Swedish Vallhunds, while Cardis come from dachshunds and collies.
