hmm. a serious thought that would sound almost like a joke:
so, a dog licks his own butt. how does this make him stupid or even less intelligent than humans?
it is hygiene. sure, its gross, but it is nature to them.
hell, we have baths/showers/soaps/shamppoos.. tons of tools to clean ourselves and some of us are still too damned stupid to take a bath!
i think shrugging off intelligence for such actions is more proof that we over exagerate our own intelligence.
