Here's why:
* Dogs use their noses to smell: Their noses are constantly wet because it helps them pick up scents more easily.
* The moisture helps with scent detection: The wetness on the nose traps scent molecules, allowing the dog to detect smells better.
* A dry nose is a sign of dehydration: If a puppy's nose is dry and cracked, it could be a sign of dehydration.
However, there are some exceptions:
* Sleeping puppies often have dry noses: Don't worry if your puppy's nose is dry when they're sleeping.
* If the nose is dry and the puppy is also lethargic, vomiting, or has diarrhea, it could be a sign of illness: If you notice these symptoms, it's important to consult your veterinarian.
In general, a wet nose is a normal and healthy characteristic of a puppy. It's a sign that they're happy, healthy, and exploring the world around them through their sense of smell.
