I was mauled by a dog so I'm not very trusting of dogs. I can not handle the breed of dog at all or outright aggressiveness. I will lose it. If I even accidentally seeing a picture for 2 seconds and I am shaking and trying not to cry. It's a very uncommon breed so not a situation I have to deal with often. But otherwise if they appear relaxed, controlled, have manners, and don't bark at me too much then I'm ok with them. If the owners don't seem to mind intrusive behaviors on strangers or think they're exempt from laws or rules, then I stay away. I don't care how "friendly" the dog is. I start wondering what else they excuse.
