8. Rottweiler

The AKC Standard describes this dog breed as a canine that possesses a self-assured aloofness and is also a courageous and calm dog. As other breeds mentioned earlier before, the Rottweiler needs a lot of socialization at an early age in order to train its territorial instincts. 

If you properly raise your Rottweiler, you will have a friend for life. They are smart dogs, and some folks like to joke that Rottweilers have hearts as huge as their bodies. So we can safely say that these big guys cannot wait to give you all their love and attention.
