There are two kinds ofWelsh Corgi Dog, and are called after the ancient Welsh country, where they originated. The cardigan has a much longer tail than his pembroke equivalent, and has more rounded ears. The Pembroke has received great publicity, because the British Royal family owns one, and is more frequently seen, but tends to be more excitable than the cardigan Welsh corgi. Both variations are good guardian dogs, and usually obedient; however, some of them have a tendency to bite if incited.
