The Pedigree Database: German Shepherd dog

One of the finest producers in the history who gives not only strength but glamour and movement also.

Fedor is obviously a great dog and is one of my favorites. I've seen the rumors that Lasso isn't his father. If that is the case, who is really his father?

Any comments on the old saying about Fedor bringing character/strength to his progeny?

thanks,
Alan...
