The main thing I don't like about dog (owners) is that you are supposed to tolerate them licking and rubbing against your trousers. Dog owners and non-dog owners would get along a lot better if dog owners would simply keep their dogs to themselves. I don't want to be introduced to dogs, thanks.
Dog owners also don't often seem to think much about how their dog's bark territorial dog-threats at whoever happens to walk by on the sidewalk. I mean, imagine I programmed a motion activated robot to yell threats at whoever walked by, that would be rather rude of me, right? But let your dog do the same, and no problem at all. People should train their dog not to bark at people on the sidewalk.
