Dogs are often said to be man's best friend. They come in all shapes and sizes, and they are great companions, but they can also be great for protecting the home. These are the protectors, the most powerful breeds of dogs.
This breed is intelligent, strong, and makes an extremely loyal companion. They are often used as police dogs because they possess a strong protective instinct. German shepherds love to be active, so they are not the type of breed you'll find being lazy very often.
