The Weiner dogs also known as Dachshund are of full breeds. They were mainly used for hunting badgers in Germany and had long body, drooping ears and short legs. They are classified in the hound or scent group of dogs. Check out http://en.wikipedia.org/wiki/Dachshund for details.
They are actually called dachshunds. They were originally bred in Germany to hunt badgers. We most commonly see miniature dachshunds who were not bred to hunt badgers, but many of them did not get that memo, and think they are plenty fierce!
