Teacup Pomeranian Dog

The Pomeranian  is a breed of dog of the Spitz type, named for the Pomerania region in Central Europe. 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%.
