In my new neighborhood, this one neighbor's medium sized male dog is almost ALWAYS loose outside during the day and sometimes walks into the street (probably because it is on a cul-de-sac). He often even visits my property while usually marking territory, etc. I haven't seen him poop on my lawn yet. The dog is very chill, not intimidating. pettable, doesn't jump on me, etc., even though he'll sometimes bark at me a little when he sees me from his property. Other longtime neighbors appear 100% fine with this and even give him attention.
I'm wondering how to handle this. I'll probably lay low (my nature) as long as he doesn't start pooping on my lawn and become more of a nuisance. After all, I don't want to be deemed a jerk. But is it strange that this dog is almost always outside (at least during the day)? If I had one, I wouldn't keep it loose. I do worry a little that a vehicle could accidentally hit him, but the owner is obviously not concerned.
What would you folks do in this situation? Lay low?
