Sorry, I don't buy that. Animals aren't mean and aggressive just because. I have friends who raise WOLVES and they're sweet, gentle animals. Animals get mean because they are taught to be that way.
It's well known that there are a lot of people who buy pitbulls and rottweillers with the intent of making them aggressive and mean. They do it with those dogs because they have such a powerful, damaging bite. I've also seen it done with German Shepards and dobermans. I grew up around German Shepards. They aren't mean and aggressive (unless someone is trespassing and that's a territorial issue) in the least....unless they are TAUGHT to be that way. In fact, I grew up in a ranch environment surrounded by animals (many kinds of dogs, cats, horses, cattle, goats, sheep, etc.). I've only seen one animal in all my life that was just a mean and aggressive animal for no damn reason and he was an Arabian stallion. Are you going to now tell me that Arabians are just aggressive and mean by nature? I've spent a lot of time around a lot of different breeds of dogs, including pit bulls and rotties, and they're no more aggressive than any other breed, much less in many instances. I know of more people who have been bitten by golden retrievers than I do pit bulls. Don't believe all the media hype about pit bulls being naturally mean and aggressive.
