German Shepherd

German Shepherds are working dogs that have recently been adopted by militaries and police forces. These dogs are qualified because they are large, clever, powerful, and dangerous dogs capable of killing people. The German Shepherd breed is ideal for thwarting human threats, weighing around 90 pounds and standing over 2 feet tall. Working dogs have been bred for generations, resulting in a highly useful tool.

Unfortunately, German Shepherds are known for their aggressiveness and territoriality, and they have accounted for 20 deaths (about 5% of all dog bite deaths) and several non-fatal bite events. However, the good news is that this breed is extremely trainable. This kind of dog must be socialized and trained in order to harness its territorial tendencies. Otherwise, they could get territorial against those you don't want them to, such as family members. In short, in most cases, they are very obedient family dogs especially if they have been socialized from an early age.
