A dog’s dry nose does not necessarily mean he is sick

It is abnormal to use a dog’s dry nose as an indicator of his health. There are many reasons why a dog has a dry nose. Generally speaking, when a dog wakes up after sleeping for a long time, his nose will be dry because he has not licked his nose for several hours. In addition, the dog's nose will also become dry if he rests in a dry room or an air-conditioned room. So before rushing to take your dog to the hospital, wait a while to see if the nose becomes moist again.
Some dog breeds are born with dry noses. For example, some dog breeds with short nasal cavities—pit bulls and pugs—have drier noses.
In addition, older dogs’ noses will be drier as they are unable to produce more nasal mucus due to age.

Symptoms of dry nose in dogs

When the color of your dog’s nose changes, or it bleeds, cracks, swells, or there are lumps and masses on the face and around the nose, please seek medical attention promptly. In particular, nosebleeds require attention. In addition, if your dog’s nose is not only dry, but also accompanied by other symptoms and behavioral changes, this is a sign of illness.

Why is a dog’s nose wet?

A dog’s wet nose can absorb more odor molecules in the air, and the hairless part inside the nose has many protrusions, allowing odor molecules to enter the dog’s nose , a series of analyzes will be completed in the dog’s brain.
The action of licking the nose helps the dog further "smell" the object. When a dog licks his nose, his tongue carries the odor captured by nasal mucus into his mouth. Scent glands in the mouth called the pirionasal apparatus allow for a clearer analysis of the chemical makeup of odors.
The wet part of your dog’s nose is made up of saliva and mucus. Although it may sound a bit sticky, a wet nose works. First of all, a moist nose can regulate the dog's body temperature, because dogs, unlike humans, do not have sweat glands on their bodies and can only rely on the sweat glands on their noses and footpads to regulate their body temperature. Therefore, a moist and cool nose can help dogs dissipate heat.
