Have you ever spoken to Wyll? I highly doubt that. He's very caring.
It is debatable how caring he really is. He says he wants to stop the goblins for the children but then reveals he came as part of his vendetta. Then reveals he has a second ulterior motive on top of that.
He comes off as a guy who likes being a hero more than saving people, hence he'd want a dog to have a dog rather than because he loves dogs. My take on him anyway.
