The Pomeranian (often known as a Pom or Pom Pom) is a breed of dog of the Spitz type that is named for the Pomerania region in Poland Central Europe. Classed as a toy dog breed because of its small size, the Pomeranian is descended from the larger Spitz type dogs, specifically the German Spitz. It has been determined by the Fédération Cynologique Internationale to be part of the German Spitz breed; and in many countries, they are known as the Zwergspitz ("Dwarf-Spitz").
The breed has been made popular by a number of royal owners since the 18th century. Queen Victoria owned a particularly small Pomeranian and consequently the smaller variety became universally popular. During Queen Victoria's lifetime alone, the size of the breed decreased by 50%. Overall, the Pomeranian is a sturdy, healthy dog. (Wiki)
