Rottweiler
The Rottweiler is one of the oldest herding breeds there is. These dogs are all about balance, intelligence, protection, and courage.
According to the American Rottweiler Club, this dog isn't for everybody because it requires a calm and stable pack leader.
They need socialization, training, and plenty of challenges.
Rottweilers are exceptional guard dogs.
A two-year-old Rottweiler was even recognized for his bravery by the United Kingdom's RSPCA (Royal Society for the Prevention of Cruelty to Animals) for protecting a woman from an attacker by leading his owner to the street and guarding the victim until the police arrived.
However, there are a lot of Rottweiler attack cases as well.
According to the American Veterinary Medical Association, Rottweilers were involved in 33 fatal attacks on people over a seven-year period.
They've even been called the deadliest dog out there. Because of these concerns, this breed is banned in Poland, Romania, Portugal, and Ireland.
