Toy breeds normally weigh no more than 20 pounds even as adults and many are smaller. Popular toy breeds include the Chihuahua, the pug, the Maltese, the Pekingese and the toy poodle. Other well-known toy breeds are the Yorkshire terrier, the Pomeranian and the miniature pinscher.
Toy breeds belong to the American Kennel Club's Toy Group. They are bred as companion dogs and are popular pet choices for people living in apartments and small houses. Many are intelligent and do well in obedience competitions. Their main drawbacks are tendencies toward excessive barking and fragility, and they may not be suitable for families with small children.
