Hormones dictate the smell. The smell gets more pronounced if it gets wet.
Try not taking a bath for a week then let a Filipino smell you. Go and wet yourself in the shower and before you can even get near that Pinoy, he'll be far away running from you already.
I'm not sure there will ever be a "dog scientist" who has the time to go on Yahoo Answers (:
It certainly is hard to fathom but it seems pretty natural that they do--not that they are dirty or anything, though the longer between baths the worse it tends to be.
One of the reasons I prefer cats, as much as I do love dogs.
There are no scientists, just as there are no vets, on this site, healthy dogs don't smell, regardless of if they're wet or not, however, improperly fed as well as dogs that are over bathed may result in bacterial/fungal skin infections, but would not occur if they were provided with the proper care, PANDA...........
I'm not sure this requires being a scientist but just some common sense; the smell comes from the chemicals they naturally have in their fur and skin. It also has a lot to do with how often they're bathed and what they're bathed with, what they eat, and their overall health the same way any animal including humans has an oder.
Seems like my common sense abilities are correct. I did the typing for you, hopefully you can point and click:

Wet dogs smell like wet dogs. Wet any other animal smells like wet any other animal. It's a question of body chemistry.
For example, some people when wet smell like wet trolls.
I read that it's something to do with the bacteria on their skin and in their coat being activated by the damp, wamness. Bacteria causes odor.
It's the same reason how perfume works or the musty smell after a rain. As the dog is drying, the water molecules bond with molecules that have odor and gets picked up by your nose.
It is all the stuff in the coat that is washed out, after a bath the smell is far less. Dogs smell like dogs. It is just part of the smell of dogs. I don't know but does a pig smell like a pig after a good bath? I think it is just something specific to the species (canine). I don't mind the smell of horses but I can't stand the smell of a dairy. Cows stink.
Because they're dogs.
And they're wet.
All that time and effort I spent earning a PhD was really worth it, wouldn't you say?
because there a wet dog
Ha. My dog would find a dead animal and roll all over it. If I gave her a bath, as soon as she got outside, she would roll and smear her body all over the ground. My belief is it is instict to not smell like humans or perfume soap to protect theirselves from enemies, preditors, possible prey, and other dogs..so yeah, when she got wet, she smelled like a SWAMP CREATURE.
They signal a presence of bacteria and decay and death to us. Their [dogs] skins mostly have Staphylococcal bacteria, which don't produce much in the way of a smell at all, but they've also got some yeasts too which are really pongy.
