I called it "Aw Crap". It was a small dog. It would always be with the kids playing in the street. I'd have to slow down to weave thru the kick ball game. The dog wouldn't chase me. It would be barking at me, the whole time running in front of me in a random zig zag pattern, so it could see me.
Now that I ride to the daycare instead of the house, I don't have to deal with him anymore.
