Has a corgi ever won best in show?

Pembroke Welsh Corgi (has never won Best in Show) Doberman Pinscher (4 wins: 1939, 1952, 1953, 1989) Australian Shepherd (has never won Best in Show) Miniature Schnauzer (has never won Best in Show)

How often should I groom my corgi?

The Corgi has a medium dense double coat and needs to be groomed every 4 – 8 weeks, with more frequent grooming during the shedding seasons of spring and fall when they change coats. As long as the undercoat is removed the outer guard coat will provide shade for your dog.
