Where does the smell of a wet dog come from?
Contrary to popular belief, it is not caused by disease, dirt, or even more so by the dog itself. The characteristic spicy, musky aroma with a hint of fruitiness comes from the yeast and bacteria that live in his fur.
Moisture and small scales of skin form a nutrient broth under a dog's coat in which various microorganisms develop. This process is completely natural for any animal. This layer is there to protect your dog's body from outside interference, and it is governed by the number of resources available: healthy skin, plus a well-functioning immune system, will keep the bacteria in check.
But where does the smell come from?
The fact is that the microorganisms that are part of this environment release caustic volatile compounds during their life activity. Together with water molecules that evaporate from a dog's skin surface, these compounds are released into the air. The higher the humidity of the air around the dog, the more intense the process.
In other words, "doggie smell" is the smell of a healthy dog. Because humid air contains more odor molecules, a particularly pungent scent comes from a wet dog and in rainy weather. Sometimes it can be quite pungent. But try to get rid of it and all you get is dry skin and a dull coat. Should you do it? The big question.
