These dogs are highly intelligent and will show undying devotion to their master but they are dogs that need company and stimulation to be at their best. It is however, important to remember that this is a working breed and that they do have certain characteristics that some people might find difficult to live with. The German Shepherd should be steady, loyal, self assured, courageous and willing and should not be nervous over aggressive or shy. Nervous aggression is something that we are now seeing more often as a result of bad breeding. It is sad but there has always been indiscriminate breeding of German Shepherds right from the start, which has lead to problems with temperament and health.
