I'm dog neutral mostly. I like well mannered and friendly dogs that are good around other dogs and children. I don't like dogs who come with caveats. If I can just chill around a dog and not have to make sure I'm not wearing a certain color it doesn't like or sitting with my arms crossed or any other thing that the dog doesn't like, I like them.
I grew up around dogs where I live, but they were mostly working dogs of some sort and not take to the grocery store dogs. They lived outside but were still considered a part of the family without being viewed as being on par with humans. When they got sick or starting biting people, they were put down by the owners.
The "ooowoo pupper doggo dress them in Halloween costumes" people and the ones that refer to themselves as dog moms and dog dads are the ones I don't trust. If you aren't capable of understanding that the effort, sacrifice, responsibility, and commitment in owning a dog is not even in the same realm as having kids, I wouldn't enjoy spending time with you.
As far as trusting a dogs ability to sense bad people goes, my neighbors have 2 dogs. One is a fantastic Irish Setter/Fox Red Labrador mix, who has been nothing but friendly and playful with my whole family from day one since they moved in. Other than shitting in my yard, it's a wonderful dog to have as a neighbor, it's welcome over here anytime. Their other dog, is some kind of mix. It doesn't like me at all, and hasn't since they moved in. So which dog should they listen to as far as if I can be trusted or not? Maybe it's possible that some dogs, like some people, are just assholes.
We don't own any dogs because they wouldn't fit into our lifestyle very well and it wouldn't be fair to the dogs. Myself and my youngest have pet allergies so they wouldn't be able to be inside the house, and my wife and I both work and are gone most of the day, except lately I've been working from home for the past couple months. I'm not willing to let a dog run loose all day and bother the neighbors while we're not home, and keeping them chained up or in kennels isn't really my thing. Even if I could keep a dog indoors, I wouldn't, it seems kinda like an asshole move to keep your dog cooped up inside your house all day while you're at work.
TL;DR version: I like nice people and nice dogs.
