The teacup and toy breeds of Chihuahuas, Poodles, Maltese, Yorkies and Pomeranians are some small pocket dog breeds. Celebrities being seen with the tiny pets on television and other media has popularized these types of dogs.
Small pocket dogs that come from licensed and professional breeders should be as healthy as any full-sized dog. The tiny dog breeds typically have big personalities and make good family pets. They can also be just as aggressive as their larger cousins. They make good watchdogs because they don't hesitate to sound the alarm for suspicious people or activities. Some small dogs can have a tendency to bite or nip, but proper training should eliminate the behavior.
