Toy?

Thunder is such a crazy dog. One of his quirks is that he loves his toy. When getting to know a new person, if they ask him where his toy is, he will love them forever. Dave says that labs are so stupid that they will play fetch until their feet bleed and still want to keep playing. That things gets so slimey. Dave wants to take Thunder camping. As long as he knows where the toy is at all times, he should have no problems.
