Papillons are small spaniels whose name is French for butterfly, after their large, fringed, upright ears. Toy spaniels of this kind appear in European paintings from the 1500s onward, and the breed developed in France and Belgium. Dogs with drooping ears are called Phalènes, French for moth, and belong to the same breed. The American Kennel Club recognized the Papillon in 1935 and places it in the Toy Group.
A Papillon weighs only about 5 to 10 pounds but is sturdier and more athletic than it looks, with a long, silky white coat marked with patches of color. Many are bright, curious and friendly, and the breed excels at agility and trick training. They are energetic, often vocal and fond of their people, and need gentle handling because of their small size.
