2. Rottweiler

Judging by this photo, it’s hard to see which part is intimidating, but just like Pitbulls, they can be extremely scary and will make you question who is in charge. They can live as long as 10 years.

And, just like the Pitbull Terrier, Rottweilers are extremely loyal and loving. This breed is known as family protectors. In addition, these dogs are CRAZY about swimming, going on walks, and many other physical exercises.

They require training from an early age in order to raise a well-behaved puppy. Rottweilers are also used as guard dogs, search and rescue dogs, and police dogs.
