Additional information (Wiki): The Papillon has the appearance of a dainty toy breed, but many owners will claim that their dogs are "big dogs in little dog suits". Some people find that their Papillon is very capable of handling a good five-mile walk. One aspect of the Papillon that has led many to believe the "big dog" assertion is this breed's surprising athletic ability. In contrast to its staid and stately representation in the Old Master portraits, the Papillon is highly energetic and intelligent. The breed is far older than any other represented by the AKC and is more notable for its psychological abilities than its athletic parlor tricks; the Papillon's true strength lies in its ability to perceive the emotional needs of its owner and to translate them into a healthy psychological environment. In other words, the animal becomes what the owner needs at the time, depending on circumstances. Provided their genetic structure is sound, and they are not the product of "puppy mill" inbreeding, they are generally healthy animals. Papillons are built for movement, and most do not need any encouragement to apply their energy to athletic activities. However, potential owners are cautioned that the breed is highly affectatious in nature.

In recent years, the Papillon has become a small dog star in the sport of dog agility. This sport consists of an obstacle course with tunnels, jumps, A-frames, and narrow bridges that a dog completes at top speed aided only by verbal and body-language commands from a handler. Agility requires the dog to spring, scramble, weave, and turn on a dime. The breed is considered naturally agile, and Papillons compete at both national and international trials. Because many Papillons have intense drive and natural speed, their tiny turning radius gives them an edge over larger dogs, and some Papillons are capable of beating Border Collie speeds on some courses. At the same time, Papillons excel in companionship and lap dog sweepstakes, and take it very seriously.

Others have experienced Papillons as highly companionable—yet physically active—dogs requiring appropriate socialization, consistent and monitored exercise, continued training (which also serves to stimulate their active minds), and daily, proactive human-to-canine interaction.
