People are just naturally more cautious around an animal that is capable of overpowering them, and rightfully so. I don’t know your dog, and it costs me nothing to just avoid any potentially negative interaction, even if the risk is low.

If a troubled chihuahua with a shit owner attacks me, no big deal, I’ll live. If a troubled pit attacks me I can kiss my ass goodbye. I don’t think anyone is personally judging you or your dog when they cross the street, some people just figure why chance it?
