Alaskan Malamute
Alaskan Malamutes were made for the harshest conditions. They are bred for isolated and cold environments. Survival skills are often activated with this breed as they have been known to attack small animals as well as children. The Malamute is another difficult breed to train, even worse if they detect a weak owner. If someone in your family suffers from asthma, they will also want to stay away from this breed since they shed a lot.
rottweiler
The Rottweiler breed is known for its strength and large size. They were originally bred for their dexterity, often used to herd livestock and pull small carts. Rottweilers can act violently towards strangers due to their loyalty and brave nature. This breed is often used as police dogs and guard dogs. They love to play, but often mistake rudeness for something real.
