Many believe that a dog's nose represents whether or not the dog is healthy. However, the dog's nose is wet if the air is humid. Within the lateral glands of the dog's nose humidity is produced. You will find that a healthy dog's nose will be dry during hot weather.

Dogs' noses aren't *always* wet. They can be wet, dry, or runny just like a human's. If a dog's nose is dry, it doesn't necessarily mean they are unhealthy. Dogs just tend to lick their noses a lot, generally if they're happy, and it will get wet and stay that way as long as they're licking.

Because he keeps licking it. It has more to do with the local humidity than his health. A wet nose helps him tell which way a smell is coming from.
