I'm sure he was defending me because it was dark and he didn't bark until the guy crossed the street and headed towards us.

but that can still be a "Look! Another person! Just thought I should let you know" bark
or it could very well be defending.

True. I'll get him to calm down. Of course, everyonw else he meets, he loves. It was only that guy.

but the point is, that he was picking up on your feeling about the guy. He won't be able to calm down if you're not calm. Easier said than done, I know.
