As far as i am aware and after a breif refresher via google, no, German shepherds have never had any wolf blood.
There ARE 'wolfdogs' out there, i think theres a czech wolf dog...
The confusion arises from the fact that the Deutsche Schäferhunde (sp?)(the original name) translated to english as German Shepherd Dog has not always been called this.
During times when all things German were not particularly popular, the GSD was called the Alsatian Shepherd or Alsatian Wolf Dog, purely to avoid the german connection and probably to make people think they are something more exotic than they are.
In 1977 though the name was changed back to the original, (i think), the correct name now is German Shepherd Dog.
This rumour is slightly less common than the usual one, which is that the Alsatian and the GSD are two different breeds. They are not!
Em (sure now some proper shep people will come and kick my butt for having got it all wrong!)
