Earlier quoted context omitted.
As someone who gets chased by a dog at least once a month on my daily commute I'm pretty sure they do want to eat me. Maybe a couple are just trying to herd me but I think you underestimate their prey drive.
I'm pretty sure they are not (unless it is a pitbull or something). Most breeds of dogs will not attack humans. They are aware of the difference in physical strength. Also, if they are real aggressive, I assume a catastrophe has already happened or is in the making (especially with a child?). The authorities have not intervened yet?
"pitbull" isn't a dangerou breed, it is a correlation signal for a psychotic owner that torture dogs to make them violent.
