Temperament. The Pembroke Welsh Corgi is highly intelligent, loyal, able and willing to please its owner. Corgis are extremely active and are good with children so long as the dog sees humans as above him in the pack order. Protective and sturdy, they make fine guards, and excellent show and obedience dogs.
