ELI5: Why do dogs smell so terrible when they are wet?
gpt
Have you ever noticed that a lot of carpet and polyester or polypropylene pile (like plush blankets) also smells horrible when wet?

What unites all of these things: dogs, carpets, fuzzy blankets, is that they all have a high surface area due to the fuzz they are covered with. That high surface area, via adhesion, accumulates lots of smelly things. Like body oils, fragrances, smoke, and wonderfully named hydrocarbons such as "cadaverine".

Water helps loose and dissolve much of this. And then, due to the high surface area, the water rapidly evaporates. Weak interactions between vaporizing water molecules tug on other stuff that's stuck to the surface, helping it to volatilize into the air.
