All Black People Love Fried Chicken. All Mexican's steal. All White People know who to fix computers. All Asian's are good at math. That's what your post sounds like to me. As a owner of a pit bull (formerly had 2 pugs, 1 rottweiler, 1 chow) I can tell you I have never had a companion as affectionate, smart, and friendly as this dog. Plus, having a very active lifestyle requires to have a dog as active as myself (gets along great with my 3 cats). Animals, just like people, can't be stereotyped, they are a product of how they are raised.
But, they can be statistically categorized. And statistically they are MUCH more dangerous breeds. "According to the Clifton study, pit bulls, Rottweilers, Presa Canarios and their mixes are responsible for 74% of attacks that were included in the study, 68% of the attacks upon children, 82% of the attacks upon adults, 65% of the deaths, and 68% of the maimings. In more than two-thirds of the cases included in the study, the life-threatening or fatal attack was apparently the first known dangerous behavior by the animal in question. Clifton states: If almost any other dog has a bad moment, someone may get bitten, but will not be maimed for life or killed, and the actuarial risk is accordingly reasonable. If a pit bull terrier or a Rottweiler has a bad moment, often someone is maimed or killed--and that has now created off-the-chart actuarial risk, for which the dogs as well as their victims are paying the price." http://www.dogbitelaw.com/Dog Attacks 1982 to 2006 Clifton.pdf http://www.dogbitelaw.com/PAGES/statistics.html
The presa canario may look scary but I think the wolf hybrids are really (potentially) the most dangerous dogs you can own. The pressure in their jaws are on par with freakin' bears.
We were on a list to get one until MrsFromWA found out she was pregnant and dropped the veto. It's on hold for a couple of years now. But they're great water rescue dogs also.
