All dogs share a common ancestor: the grey wolf. While this relationship is fairly apparent in breeds such as the German Shepherd or Spitz-type dogs, with their wolf-like heads and pricked ears, it is hard to see the connection between wolves and Toy Poodles or St. Bernards. Genetically, however, any dog of any breed is virtually identical to the wolf. The transition from wolf to the huge diversity of domestic dogs known today happened relatively quickly. The process began gradually, with random changes in size and shape, but accelerated when humans began to selectively breed those dogs that exhibited characteristics they desired.
