What designation were the two Corgi varieties often registered under before the formal split in recognition occurred?

Welsh Corgis

Prior to the official separation mandated by major kennel clubs in the 20th century, the ancestral lines of the Cardigan and Pembroke Welsh Corgis often coexisted without strict categorization. During this period, when the physical differences were less formalized or the breeds had not yet undergone standardized scrutiny, they were frequently registered collectively under the general heading of 'Welsh Corgis.' This practice of cross-registration sometimes complicated the tracking of ancestral waters. The eventual need for separation arose because the distinct genetic origins of the Cardigan and Pembroke had solidified into two types that breeders consciously decided needed preservation as separate entities, necessitating separate registration in the 1920s and 1930s.
