Not that you ever WANT your dog to dive into a pile of feces, but they usually wait until you've given them a bath, scheduled company to come over, or spread a fresh load of laundry on the couch. It's one of the worst habits of the canine world. Even worse, no one quite understands the drive behind it! There are plenty of interesting theories, though, so why not take a look through them?
