    Although it seems unfair and outdated, breed-specific laws continue to exist in the United States and across the globe in an effort to reduce the number of dangerous dogs. The laws are extremely difficult and costly to enforce, but many communities continue to outlaw certain breeds they deem "threatening." Organizations such as the ASPCA and the Humane Society are completely against them, stating that there is no evidence that communities are safer because of these laws. Plus, the United States Centers for Disease Control attests that inaccurate dog-bite data makes it near impossible to identify specific breeds. Still, many breeds — particularly Pit Bulls and Fila Brasilieros — suffer from negative reputations. Here are 12 of the most commonly banned dog breeds in the world.

    Breed: Alaskan Malamutes

    Why they made the list: Alaskan Malamutes can be trained, but they are not for just anyone. They are extremely active and demand a lot of exercise. Because they have a strong prey-drive, their instinct is to hunt down anything they feel endangered by. This can result in fatalities.

    Breed: Doberman Pinscher

    Why they made the list: In a recent study, conducted to determine whether there are breed differences in aggression, the Doberman Pinscher ranked relatively high on stranger-directed aggression. Their aggressive behavior was displayed depending on each situation, but overall, their size and strength makes them a potentially dangerous dog breed.

    Breed: Neapolitan Mastiff

    Why they made the list: Although many people do not associate Neapolitan Mastiffs with dangerous dogs, they are illegal to own in Singapore. In order to own one in Romania, one must pass a psychological evaluation. The 200-lb. dog can be dangerous when fully grown and should not be around children.

    Breed: Pit Bulls

    Why they made the list: Allegedly, several studies conducted have resulted in evidence indicating that Pit Bulls are responsible for many human attacks. One study concluded that Pit Bulls were responsible for 42–45% of dog attacks, with children being the victim 70% of the time. Pit Bulls are restricted widely around the world, from Miami to the entire U.K.

    Breed: Perro de Presa Mallorquin

    Why they made the list: Like their cousin the Perro de Presa Canario, Perro de Presa Mallorquins are extremely intelligent and powerful dogs. They are not easy to handle and were bred to be fighting dogs. They can stand up to almost any challenge and if they are not taught to be obedient, they can become extremely dangerous creatures.
