Why dogs stink. He smells like a dog, the client says. Being as he is a dog, this doesn't seem to me to be a problem, technically. If, being a dog, he smelled like, say, a camel -- now that would be a problem. Of course, this is not the truly stinky dog. Every dog has a tendency to smell a little strong when wet. If you can love your dog when he's wet, then you really love your dog. Something about being wet, or even just a really humid day, brings out that doggy odor. That's not too bad, though.
