Pembroke Welsh Corgis are very affectionate, love to be involved in the family, and tend to follow wherever their owners go. They have a great desire to please their owner. Besides herding, they also function as watchdogs due to their alertness and tendency to bark only as needed. Most Pembrokes will seek the attention of everyone they meet and behave well around children and other pets. It is important to socialise this breed with other animals, adults, and children when they are very young to avoid any anti-social behavior or aggression later in life. Due to their herding instinct, they love to chase anything that moves, so it is best to keep them inside fenced areas. The herding instinct will also cause some younger Pembrokes to nip at their owners’ ankles. (from Wikipedia)
