I never understood why my high school buddy was so afraid of dogs. I would tease him sometimes because when he saw a large dog, even on a leash, he would edge to the other side of me and act nervous. He's a big and typically brave dude so it was out of character. Plus I just never had a concept of dogs as dangerous based on my childhood experiences.

He eventually explained that he grew up in the poor neighborhood, where people keep large, poorly trained "guard dogs" that occasionally escape and roam the streets. As a child he had to evade roaming dogs several times, including one occasion where he genuinely believes he was running for his life. Apparently it fucked him up pretty badly. Poorly trained dogs (especially those that are bread for aggression) are no joke, even to full grown adults.

Not that I can remember. Therefore...? What's your point?
