[THEFERMANATOR]

Like Destroyer said, dogs can smell fear. And if you are afraid you are most likely to be bitten. Dogs no matter how domesticated they get, are still animals. And animals respond to fear. Domesticated animals respond agressively to it as they feel that if you show fear to them, there is a good reaso nfor them to become aggressive. I've only been bitten once by a dog, and it was by a small terrier that knew me of all things. BUT I opened the door to a friends house and didn't exert confidence like I normally do, and it got me bit. I've walked into other peoples places where they had dogs that they swore would eat anybody alive, and most of the time they will come up to me and be as friendly as can be. It mostly boils down to how you respond around the dog, and if you have any fear of them. I know it's tough, but any fear(even fear you don't show) can be sensed by an animal. And they will react to the hidden fear the most violently most of the time.
