It's not the grizzly bear, it's the humans who hike near them.
I understand your response, Fly, but it is not a valid comparison.
Well bred pitbulls are one of the finest family dogs someone could own. They are protective of pets, children and the whole family if they are a properly bred and raised Pit.
Look at the Pit news articles. Are they in the urban areas or rural areas (where there are plenty of puts too).
The reason that pits get a bad rap is that they are tenatious and do not quit. That is not only in bad behavior but good (like playing with a ball or stick).
All dogs are are a potential threat if they are bred poorly, raised poorly, trained poorly and treated as if they are another family member (they are not, they are a dog, an animal, and must understand submission to the owner).
Belive what you want, but in all my years of dog training in behavior modification and attack work, it is a small percentage of the dogs that are the real problem.
God bless
