I know there are PLENTY of responsible dog owners out there. I've got friends with dogs (although two cats own me LOL) and they are very responsible. I think it's just the location where I live. Lots of "yuppies" who think they can do as they please.
I kinda felt bad for the dog. He looked very confused after I tripped over him and started yelling at his owner. But he didn't bark or get mad in any way. I think he was just curious and moved over to me as I was coming. I was looking down, TRUSTING that the owner would do the right thing so I never saw the dog coming. I didn't even know what had tripped me up until I had started to go down.
The dog was smarter than the owner in this case, because it knew to shut up and not patronize me.
