Have you ever stopped to wonder why some dogs are so dog-gone cheerful? It's kind of pleasant, isn't it, to be around a happy dog? On the other hand, we usually try to steer clear of dogs who appear to be kind of grumpy. That's the way it is with people, too. It's much nicer to be around people who have a cheerful attitude than someone who's always looking on the dark side of things. You know, if you look for them, there are lots of reasons to be happy.
