3. German Shepherd

It’s not hard to see why German shepherds are among the most intelligent dog breeds in the United States. With a regal attitude, this breed is athletic, intelligent, and has a protective instinct.

German shepherds have qualities ideal for various hard jobs, such as guide dogs for disabled people, service police dogs, bomb-sniffing dogs, patrol dogs, or even actors.

This breed is also an excellent family dog. It is easy to train, extremely loyal, and behaves well around children, but remember that it is a high-energy dog breed and needs a lot of exercise.
