German Shepherds often compete and excel in obedience trials and Schutzhund competitions. German Shepherds are also often trained as police dogs, due to their trainability, size, work drive and look which commands respect, but is not too scary.

The proper English name for the breed is German Shepherd Dog (a literal translation from the German "Deutscher Schäferhund") but they are usually informally referred to as GSDs or simply German Shepherds. In addition, the sobriquet police dog is used in many countries where the GSD is the predominant or exclusive breed used in the canine police force.

Alsatian is also commonly used in the United Kingdom and countries of the Commonwealth of Nations. After World War I, a few dogs were taken to England and the United States. At that time, the English owners renamed the dog as the "Alsatian Shepherd", as it was feared that the breed's original name could be an impediment due the anti-German feelings still present after the War. Only in 1930 did the British Kennel Club authorise the breed to be known again as German Shepherd.

Well-bred GSDs have powerful jaws and strong teeth, can develop a strong sense of loyalty and obedience, and can be trained to attack and release on command. Poorly bred GSDs such as those from puppy mills can be fearful, overly aggressive, or both. GSDs (like Pit Bulls, Rottweilers and Dobermanns), are often perceived as inherently dangerous, and are the target of Breed Specific Legislation in several countries. If a GSD is violent or aggressive, it is often due to the combination of poor breeding (bad nerves) and the owner's lack of control or training.
