The little dog starts yapping and it takes Bruce a moment to realize it's probably because of his size. His ears drop back and somehow he manages to bring his head a little lower toward the ground.

He looks around, as if trying to convey that there isn't any other dry places to sit before hesitating and then flopping down next to the building, still out in the rain but tucking up against the cold brick as tight as he can, as if it might help block some of the rain.
