I got attacked by a dog when I was in high school. The thing honestly did jump out of a bush and take a chomp on my leg. It was coming around for a second pass when the owner caught it.

I'm still a bit spooked by dogs so my "don't pay them any mind" remark was basically saying that I keep an eye on what they are doing, but as long as they just chase, I'll keep doing what I was doing.

However, I have seen a dog get hit by a car because the dog was running across the road to chase me. I'm sure it was a very nice dog.
