The Affenpinscher, also known as the “Monkey Dog” (“affen” means “ape/monkey” in German, and “pinscher” means “terrier”), is small but feisty, full of spunk and energy. This mustachioed little devil is descended from the numerous small terriers that populated 17th and 18th century stables and shops throughout Europe, ridding them of rats and mice.

With compact bodies, baby-doll faces, and fluffy white hair, Bichons are a very appealing breed whose looks are enhanced by a perky, good-natured disposition. They are often mistaken for white Poodles.

Comical and curious, this intelligent and devoted dog loves to spend time with his people, whether it’s going for walks, running errands, or playing with the kids. A member of the Bichon family of white, fluffy dogs — he’s also known as the Bichon Bolognese — he originated in the Italian city of Bologna, from which he takes his name. He excels at manipulating people to get his way, and can be difficult to housetrain, so be patient and consistent.

The Boston Terrier may have been bred to be a ferocious pit-fighter, but you’d never know it today. The little American Gentleman, as he was called in the 19th century, is definitely a lover, not a fighter, although males have been known to show their terrier ancestry with a bit of posturing when they feel their territory is being invaded by another dog.

Brussels Griffons, often called Griffons for short, originated in Belgium, where their hunting skills were used to keep stables free of rats and mice. They eventually became more popular as house pets, and these cheerful, curious, and affectionate dogs do make great companions — for the right person. They’re sensitive, sometimes moody and high-strung, and more than a little demanding of their owner’s attention

The Cavalier King Charles Spaniel is a beautiful small dog that undoubtedly is a contender for the title of “top tail-wagger.” In fact, among the characteristics that Cavalier breeders strive to attain is a tail in constant motion when this breed is moving.

The Chihuahua is a saucy little hot tamale and not just because of his association with a certain fast-food Mexican restaurant. He’s renowned for being the world’s smallest dog, but he may well have the world’s biggest personality stashed inside that tiny body. That larger-than-life persona makes him appealing to men and women alike.

The Chinese Crested is an exotic-looking small dog who does not actually hail from China. He’s found in two variants: the Hairless, with silky hair on the head (the crest), tail (plume), and feet (socks); and the genetically recessive Powderpuff, who has a full coat. Both variants can be found in a single litter.

For the smart and sweet-natured Coton de Tulear (Coton for short), the perfect day consists of nothing more than being with his person, whether it’s lying at her feet while she works, following her from room to room — not even the bathroom is sacred — or going for a ride to Starbucks.

Don’t let the Dachshund fool you. He might be, as legendary literary critic and humorous journalist H. L. Mencken said, “half a dog high and a dog and a half long,” but this small, drop-eared dog is tough enough to take on a badger. In fact, that’s what he was bred to do and how he got his name
