#2 GERMAN SHEPHERD
Unlike many others on this list, the German Shepherd is a relatively new breed whose origins date back to just 1899. Though the German Shepherd is now one of the most popular dog breeds in the country, its popularity suffered a serious decline during the years following World War II due to anti-German sentiments.
Today, the breed is known for their protectiveness and willingness to learn and be trained. They are often seen being utilized as police and military dogs, detection dogs, and guard dogs for civilians. They have an average lifespan between 9 and 13 years.
