The Czechoslovakian Wolf-dog (not a wolf and not a dog)
It is not often that conservative kennel authorities recognize a new breed of dog. It is even less usual when the "dog" is the result of breeding animals usually thought to belong to different species. That is part of the mystique of the Czechoslovakian Wolfdog, a relatively new breed arising from an experiment conducted in 1955 that involved cross-breeding a German shepherd dog with a Carpathian gray wolf.
