Why Do Dogs Have Wet Noses?

What Makes a Dog’s Nose Wet?

The wetness of a dog’s nose comes from a mixture of saliva and mucus. Their noses secrete a thin layer of mucus but dogs add even more mucus and saliva by licking their noses frequently.

Having a wet nose serves a few vital functions for dogs. First, a moist nose helps dogs to regulate their body temperature. Because dogs don’t have sweat glands all over their bodies, they rely on sweat glands in their noses and the pads of their feet to help maintain their temperatures.

A moist nose also aids to their amazing sense of smell. When a dog licks their nose, they are also helping themselves to smelly even more deeply. When doing this, the dog’s tongue picks up some of the scent particles trapped in his nose’s mucus. When he touches his tongue to an olfactory gland on the roof of his mouth, it allows him an even more distinct reading of the chemical compounds that make up odors.

My Dog’s Nose Is Dry, Should I Be Worried?

It is not abnormal for your dog to have a dry nose at times. A dog’s nose my be dry after waking up from a long sleep simply because they haven’t been awake to lick it. Sleeping in a warm room with low humidity levels may also contribute to a dry nose. Before worrying, see if his nose becomes more moist throughout the day.

Some dog breeds may also just have drier noses; flat faced breeds can’t always reach their nose to lick it. Also, older dogs may produce less mucus causing their nose to be more dry.
