Want to know what (statistically speaking) is the most temperamental breed of dog? The dachshund. They bite more people every year than any other breed of dog. You know why you never see it in the news? Because they're tiny, and really can't do a ton of damage. News casters know that stories like dog bite stories do faaaar better when they are able to evoke fear in the reader. Dachshunds aren't scary.... But you know what breed is?
Not Golden retrievers, America's family pet, who ranks rather high on the list of most dog attack instances in the US. No, think scarier: Pit Bulls.
If people would just stop being stupid and look at the statistics and the temperament of individual dogs instead of being - lets face it, RACIST - and judging an entire breed of dogs by the actions of few based on information obtained from biased sources then maybe they would realize that these dogs are fantastic, loving family pets.
They were once called the Nanny dog for a reason - they're very gentle and great with kids. Dogs, no matter the breed, are what you raise them to be. You mistreat them, abuse and neglect them, don't socialize them... you're going to get a vicious dog, whether its a pit or a chihuahua.
