Might pet owners be friendlier than those who are not?

I have always been an animal lover and usually find it easier to chat with and befriend people who are likeminded. I believe that dogs in particular are able to sense those folk who are not genuine or have a dislike for them. Might it be that a caring/nurturing nature in people
is detected by dogs which makes them feel safe and unthreatened?
If my pet doesn’t like someone, I am also wary. I trust their instinct more than my own.
