Rottweilers
Before pit bulls gained their well-known reputation as dangerous, the rottweiler was first on the list of most dangerous dog breeds. These powerhouses can easily grow up to 120 pounds and still remain in good health.
They are quite large and have a temper that can easily break bad when something goes south. To be more specific, they are quite friendly and protective of those in their own home. But that protection doesn’t always include any guests.
German Shepherds
German Shepherds are known to be workers with a history in law enforcement and the military. They are the smartest, most powerful, strongest, and most dangerous dogs, with the capacity to easily inflict deadly attacks.
On average, they weigh around 90 pounds and can reach a height of 2 feet. They are also an amazing asset against human threats, especially after many generations of breeding that made them one of the most effective weapons. While German Shepherds can be quite aggressive and territorial, they also account for plenty of non-fata bites. Luckily, they can be easily trained.
