dogs are naturally not mean but they are brought up like that by men......but for your question the answer are 1.PITBULL 2.ROTTWEILERS 3.GERMAN SHEPARDS 4.HUSKIES 5.ALASKAN MALAMUTES 6.DOBERMAN as far as i am conserned........did you get what you where searching for................TOODLES
Dalmations arent good w kids and neither are chiuauas(sp?). German schepards are really territorial and olny good w a single adult. If u are a married adult w kids or wout kids it could choose a favorite and harm everybody else to protect u.
The meanest breed of dog has to be the humans that make them that way... here's a little knowledge, chiuauas bite more people in the US then pitbulls, German shepards, rotwilers, and dobermans combined!
The meanest, orneriest dog that would chase and bite anyone if he got a chance was a pet of my children--he was a white Spitz--beautiful, but mean. The sweetest dog we had (who loved children and particularly stayed close to watch over our little Downs Syndrome grandchild)was a pit bull. She was smart and loved to lie down by our feet. Some neighbors knew we had a pit bull, but didn't know what one looked like--we also happened to have a Boxer, a sweet but silly dog--anyway, our neighbors were all afraid of the Boxer (because she looked "mean?????.") Any dog, treated wrong, can become mean.
As above mentioned, It's all dependent on how they R raised. I answered re: Pits, just this morn. Also, would U like a "pet" dog? or a "working" dog? The meanest behavioral traits in any breed shows early. I am going w/Chihuahuas. U wouldn't think so, but they sometimes can sport a huge spiteful and annoying attitude!
There is no breed that is by nature mean, Dogs only become mean due to Human error , neglect or mistreatment. P.S. I have a Pitbull and have had 2 before her ,none of them mean that is media hype and ignorant banter.
Both the Fila Brasileiro & Presa Canario are known to be extremely aggressive with strangers. They are protective of those who raise them. German Shepherds are wonderful family dogs. If trained as a police dog, they live with their handlers & are part of the family.
