However, these pups are hunting dogs that are known for having a bite force of 700-800 PSI because of their robust jaw structure and muscular build.

These no-fat, only muscle dogs can cause a massive amount of destruction, just like you have seen in the series, and should be equipped with proper training and socialization from a young age.
2. Rottweiler

The Rottweiler is a massive canine mound of extreme muscles. Rottweilers were originally bred to herd livestock and work as guard dogs for Roman legions. These black and tan puppies are a highly misunderstood breed due to their heavy, muscular build and stern nature.

These butcher dogs that have been used to pull carts have a bite force of 328 PSI, which is higher than the bite force of the popular German Shepherd.

Britannica states that the large heads and muscular bodies of rottweilers need enough space to live and prosper. Ideally, a home with a big fenced yard is the perfect living situation for a rottweiler. These pups have high energy and need adequate physical and mental stimulation to keep them happy and healthy.
