Papillons are toy spaniels from France and Belgium, and similar little dogs show up in European paintings from the 1500s. The name is French for butterfly, after the large, fringed, upright ears. Some Papillons have drooping ears and are called Phalènes, but they're the same breed. The American Kennel Club recognized it in 1935.
A Papillon weighs about 5 to 10 pounds, yet it's sturdier and more athletic than it looks. The long, silky white coat with patches of color has no undercoat, so grooming is lighter than the coat suggests. Papillons are bright, curious and often vocal, and many love agility and trick training. Because they're so small, they need gentle handling and supervision around bigger dogs. Each dog's personality varies.
