From the AKC website:

“The Cardigan Welsh Corgi is a masterpiece of the breeder’s art: Every aspect of its makeup is perfectly suited to moving cattle, and yet it is so congenial and sweet-faced that it would be a cherished companion even if it never did a day’s work.
…..  Cardis are trainable, faithful, and vigilant guardians with a ‘big dog’ bark. Well-socialized Cardis are especially fond of kids and agreeable with other pets. These athletic, rugged herders have a love for the outdoors, and they thrive on mental stimulation and physical activity.”
