Payson is really none of the above. I guess if I had to pick one, aggressive would fit the best... however, he's more fear aggressive.

If I'm taking him on a walk and we pass by another dog who doesn't really respond or notice him, Payson's fine and will ignore him and continue on his way. If the dog barks, however, Payson gets really scared and tries to run the other way. There's one yard in my neighborhood with these dogs that are always out and always bark at anyone who passes and Payson refuses to go anywhere near the house.

As I said, Payson is a little fear aggressive, however. We tried taking him to the dog park to get him used to other doggies. For the most part he'd stay by himself and run whenever any dog walked by him. However, when dogs came leaping at him he'd start growling and if they didn't go away, he snapped at them. That put a stop at our dog park trips.

He did, however, get along ok with a couple of my coworker's dogs. Although they didn't play, they all tolerated each other fine.
