There are varying standards around the world as to the ideal size of the breed, but they are always larger than their smaller cousins, the Pomeranian. They were developed in Japan in the 1920s and 1930s by breeding a number of other Spitz type dog breeds together. While they are a relatively new breed, they are becoming widely popular due to their favorable temperament and other features. Active, loyal, and bright, the Japanese Spitz are known for their great courage, affection, devotion and amiability making them great watchdogs and ideal companions for older people and small children. Most Japanese Spitz are good watch dogs, despite their relatively small size, and they have a tendency to bark to warn of arriving strangers.
