So what is the advantages of such a cross?We have a popular national dog breed called "vlčák" Czechoslovakian wolfdog - it´s a recognized breed containing 3/4 German shepherd blood and 1/4 Carpathian wolf. Even that small share of wolf makes majority of these dog unable to be properly trained in protection and police work. They are more shy than normal dogs and try to escape from difficult situations. They will bite if you disobey their warning (they are very vocal), but many are unable to attack an unknown human on command - unlike German shephard.
