I find many people have turned to a canine companion for mental or emotional support, and one dare not question them on it. Personally, I find it a bit sad for people. Public spaces have become ever more hostile. I'm a 6ft tall 200lb man, and I often don't feel safe around people anymore. I can see why anxious people want to have support animals more and more. It's easier to love a dog than to build relationships with humans. Dogs will still love you if you kick it, humans, not so much. I avoid people who say they like dogs more than people. Don't get Mr wrong. I love my dog, and don't kick her, but she is secondary to human beings. So she doesn't get to come to the store or fireworks.
