Why do dogs have a "wet dog" smell?

I have had several dogs over the years and it does not matter what kind of fur they have they all have that same or similar smell that just stinks. What causes this?

Dogs have sweat glands, just not for the purpose of thermoregulation. The distinct "wet dog" smell is from apocrine glands which are associated with every hair follicle on a dog. The purpose of these glands is to seal the outer layer of the skin (which is why it's an oily secretion) and also acts as a pheromone.
