In temperament it is lively, alert and friendly, and sturdier and more energetic than its delicate look suggests. It learns quickly, and it has done well in obedience and agility competitions.
Bred as a companion, the Papillon is a small, fine-boned dog, slightly longer than tall, with a dainty muzzle and large, heavily fringed ears. Its single coat, without an undercoat, is long, straight and silky, forming a frill at the chest and a plumed tail carried arched over the back; that tail is said to have earned it the old name squirrel spaniel. The coat is white with patches of colour, ideally with a white blaze dividing the face.
The Papillon's long history as a court companion is recorded largely in art. Dwarf spaniels resembling it appear in paintings by Titian, Rubens and later Fragonard, and for centuries the drop-eared form was the usual one. During the nineteenth century the erect-eared type became more fashionable, and breeders in France and Belgium settled it into the dog known today. Both ear types can still turn up in the same litter, and in Britain they are shown as one breed.
