Bichon is the name for a type of related non-sporting category dog breeds. They vary in appearance, but all have tails curled over their back, fur that doesn't readily shed, short snouts, drop ears, and large, dark eyes. They were all bred to be amiable companion dogs and have a friendly, alert temperament. Their life expectancy is 15 years or more. The Bichon Frise, a type of bichon, is sometimes simply called a bichon in North America.
Etymology and History 
The word bichon comes from Middle French bichon ("small long-haired dog"), a diminutive of Old French biche ("bitch, female dog"), from Old English bicce ("bitch, female dog"), related to Old Norse bikkja ("female dog") and German Betze ("female dog"). Some speculate that the origin of bichon is the result of the apheresis, or loss of syllable, of the word barbichon ("small poodle"), a derivative of barbiche ("shaggy dog"); however, this theory is unlikely, if not impossible, despite the apparent similarity of the two words, due to chronology: bichon is attested from 1588, but barbichon does not appear until 1694.
The Bichons are descended from the ancient ancestors of the Poodle, the Barbet. From this, the Barbichon, a small curly coated water spaniel and another name for this family, was created. The Bichons are a Mediterranean breed, generally named for the region from where they originated. The original breeds were the Bichon Tenerife, from the Canary Islands; the Bichon Maltais, or Maltese; and the Bichon Bolognese, or simply Bolognese. There is argument on whether the Tenerife is the original stock for all Bichons, or whether the Maltese (which seems to be an old type found on the islands before even the Barbet was known) is the progenitor of the Bichons, through its breeding with the Barbets. Ultimately, most of the modern Bichon breeds have developed by introducing a variety of dogs to the Barbichon type, creating a family with recognizable characteristics in both temperament and type but no single distinct progenitor.
The Bichons were the court dogs of medieval Europe, especially finding favor in France, Italy and Spain. The French word bichonner, which means to pamper or doll up, derives from the be-ribboned and lavish lifestyles of the Bichon of Henry III of France, who was carried in a little basket wherever the King went.
Bichons buzz around with energy and suffer from separation anxiety. This act is often called the 'Bichon Buzz' or the 'Bichon Blitz'. When the Bichon Frise begins to buzz or blitz in the home, the breed will go from one room to the next, jumping on and off couches, beds, love seats, or chairs. As a result, the event can be quite entertaining. However, after the Bichon has spent his energy, he will lie down and collapse from exhaustion. 
The Maltese is undoubtedly ancient, and dogs of its type, with long hair and dropped ears, were associated in ancient Greek and Roman times with one of the two islands with the Roman name Melita (Malta or Mljet). In earlier imagery of the breed, it is shown with wavy fur, more typical to the Bichons, and it is only relatively recently that a totally smooth coated Maltese has developed as the final type. The Romans selected for a pure white coat from the very early multicolored Maltese-like dogs. The Maltese has steadily retained its popularity throughout the centuries, unlike any other Bichon, most of which became very rare at least once in their history as fashions and governments changed.
The modern Bichon Frise was created by combining the Tenerife with the poodles and barbets of the day to produce a Bichon with a coat that is tightly curled, rather than wavy—hence the full name, Bichon a poil Frisé. Only white, and white tinged with buff, are allowed in the show ring. The Bichon Frise is a very cheerful breed which can easily be seen by the way its tail cheerfully curls up high on its rump. They were very much in vogue in sixteenth-century France; they displaced the Maltese in court as the favorite. Today it is popular in Great Britain, Italy, France, and North America.
The Tenerife also traveled to Reunion Island to develop the now extinct Coton de Reunion, which then traveled to nearby Madagascar and became the Coton de Tulear. It is one of the few modern breeds that developed through natural selection and therefore comes in a range of colors.
The Bolognese was already being developed as a toy dog as early as the 11th century in Bologna, Italy. A favorite gift between courts, the little dog traveled to places like Spain, Belgium, France, Russia (as a gift to Catherine the Great) and Austria. They only come in pure white.
The Bichon Havanais, or Havanese, seems to have been descended from a variety of small, Bichon-type dogs that traveled with Spanish and Italian sailors to Cuba. They were possibly bred with a now extinct poodle type from South America to produce a wavy coat which was also silky, but it may be that they simply expressed a wavy coat trait through a random chance of genetics. In appearance, breeders prefer a "natural" look, allowing all possible colors and letting the hair grow long. It is a rare dog breed.
The Löwchen is an enigma. Though classically considered a Mediterranean Bichon dog, research into the origins of the dog show it may not have passed through the Mediterranean at all to travel to its current originating countries of Germany and the Netherlands. It is possible that the breed had some Bichon blood, or that it's simply a terrier type from Tibet with no connections at all to the Bichons. It does have a typical friendly Bichon temperament, though. It comes in all colors.
Specifically in Russia, other Bichons were developed. After the retreat of Napoleon's army, left behind Bichons, primarily the Bolognese and Bichon Frisé, were bred into a unique breed called the Franzuskaya Bolonka. After World War II, the French Bolonka was then bred with poodles and silky terriers such as the Yorkshire Terrier to produce a small dog with a multi-coloured, long, wavy coat, called the Tsvetnaya Bolonka, or Multicoloured Bichon. Until recently, these breeds were unknown outside of Germany and Russia.
The Modern Bichons 
Despite their current popularity, almost all Bichons, even the very popular Frise, went through a period of decline in the 1800s. Court dogs became less fashionable in Europe at the turn of the twentieth century, leading to the loss of many Bichon types. Breeds like the Havanese and Bolognese are recovering from this period, and even more common Bichons like the Löwchen and Bichon Frise were almost extinct at the beginning of the 20th century.
Today Bichons have again gained in popularity. The qualities that made the Bichon family of dogs popular at court also make them suitable as house pets. Bichons are bred to be small, charming companion dogs with even temperaments and playful attitudes. They are good with children while maintaining alert watchdog abilities. A playful temperament is judged to be particularly important to the Bichon Frise. Properly bred Bichons should not be yappy, stand-offish, nervous or aggressive.
The modern Bichon Frise came to North America in the 1950s, and was admitted into the AKC (American Kennel Club) in 1972. They are not shown in the Toy Group, but in the Non-Sporting Group.
