The dog's naval cavities and nostrils are made up a complex system of bones-such as like a web. This increases its surface area in which it can contact smells, so this is also why dogs have such a keen sense of smell.
No, not all dogs have black noses. Some dogs have pink noses, or even white. Some dog's noses are black to keep their nose from getting a sunburn.
Most puppies/dogs have wet noses and sometimes they get dry but not for long wet noses are a good sign

It is a sign that they are healthy. I am pretty sure they lick their noses when they are well, and when they are sick, they will not. So don't worry if your dog's nose is wet- it's a good thing!
