The Papillon ['pæp i ,jɑn] (French for "butterfly") is a small, friendly, elegant breed of dog of the Spaniel type, distinguished from other breeds by its large butterfly-like ears. The Papillon is one of the oldest of the toy Spaniels.
Papillons were bred for companionship, and make excellent watch dogs.(Wikipedia)
The Papillon has the appearance of a dainty toy breed, but many owners will claim that their dogs are "big dogs in little dog suits". Some people find that their Papillon is very capable of handling a good five-mile walk. One aspect of the Papillon that has led many to believe the "big dog" assertion is this breed's surprising athletic ability.(Wikipedia)
