Notes
Small toy spaniels, usually white with red or black patches, have been depicted for over a thousand years. They most likely originate from toy variations of hunting spaniels, or possibly Asian toy dogs. Phalène-like dogs can be seen on numerous painting from several hundred years ago, while the Papillon variety did not appear until the late 1800's.
The Papillon is considered the world's only working toy breed, and has been trained to be a rescue dog, among other things. There are also Papillon obedience champions.
Both varieties (Papillon and Phalene) should give the impression of being elegant toy spaniels with a beautiful abundant coat. The muzzle is shorter than the skull, with a clearly marked stop. The lips should be dry. The eyes should be rather large and expressive. The ears are set rather far back and well apart. They can be hanging (phalene) or erect (papillon). The body should have a deep and broad chest with straight back and slight tuck up. The tail is set high and curved over the back. The coat lacks undercoat, and should be shorter on the head and frontsides of the leg, and longer on the neck, backsides of the legs, underside and tail.
