The Papillon /pæpijɑn/ (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.[1] The Papillon is one of the oldest of the toy Spaniels.

Papillon from 1915
Papillons were bred for companionship, and make excellent watch dogs.
