Okay, maybe not “strong like bull”, but kind of strong. I’ve always loved dogs. They’re the best, best, best. But above being adorable and a great companion, they also help to keep your place just dirty enough. We’re living in a world that’s too clean, with parents who are too protective. As a result, the instances of less-dangerous–but longer lasting–immune dysfunctions have increased. Having a dog at home causes just the right amount of bacteria to strengthen the immune system to combat lower-level immune sickness.
That’s science, dog.
