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.
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.
Czechoslovakian Wolfdog
Why they made the list: The Czechoslovakian Wolfdog is quick, energetic and extremely fearless. They have a very high prey drive and are extremely unpredictable. They do not make for good household pets and should be kept far from children.
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.
Presa Canario
Why they made the list: In 2001, a 33-year-old woman was killed by two Presa Canario-Mastiff mixes. In 2006, a 30-year-old woman was killed by her own Presa Canaria. Last August, a woman was killed by several dogs in Georgia, two of which were Presas. They are prohibited in Australia and New Zealand.
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.
