The Short Answer

Dogs produce an oil naturally that has a slightly yeasty smell, (the so-called dog smell). This oil is produced to protect the dog's skin and hair. Most often, dogs end up picking up bacteria on their skin when they are outdoors. The combination of the oil and bacteria produce what many call the "wet dog smell". Dogs don't sweat over much of their bodies, however they do sweat on their nose and paws. That, combined with any bacteria they run in to, most likely explains the smell.
