A dog’s sense of smell is its most potent weapon. Dogs rely primarily on their sense of smell, unlike humans, who rely mainly on their sense of sight. Not only does the dog’s nose assist it in navigating its environment, but the whiskers also contribute to the animal’s acute sense of spatial awareness.

Throughout the day, the level of wetness and temperature in your dog’s nose may shift. For example, when you look at the glass at various times of the day, you can see more tiny nose markings pressed into the glass. We believe that wet noses define healthy dogs.

The question here is why a dog even has a moist nose in the first place. Let’s talk about a few reasons a dog’s nose gets moist.


Mucus is naturally produced in a pup’s nose, resulting in a thin covering over their nose, which absorbs and retains the particles of the aroma.

Imagine how your mouth waters whenever you think about or see something that makes you hungry. Dogs experience something quite similar, although it takes place via their nose rather than the mouth.


To boil it down, dogs tend to simultaneously smell with their mouths and noses. The Vomeronasal organ, often known as the Jacobson’s organ in a more colloquial sense, is an additional olfactory organ in dogs. This organ enables them to detect volatile odors.

This organ, which is situated in the nasal cavity and extends to the roof of the mouth, amplifies their sense of smell to the incomparably more potent than our own. More powerful than our sense of smell by a factor of between one thousand and one hundred thousand!

Dogs lick their noses because doing so stimulates the production of mucus, which traps scent particles and enables them to have a heightened sense of smell by activating Jacobson’s organ.

In addition, dogs will lick their noses to remove any debris they may have picked up when they had their noses to the ground sniffing. Dogs are more intelligent than we give them credit for, and it is in a dog’s nature to keep their nose wet. So dogs licking their nose lets them perform to the best of their capacity regarding their sense of smell.


Our dogs are all over the place when they are allowed to run free in the yard. They are continually poking their heads into things like grass, dirt, plants, shrubs, water, and anything else that is constantly sticking they can get their hands on.

Since our puppies rely on their sense of smell to help them navigate the world around them, it stands to reason that if they can smell something, they will sniff it. As a result, they are susceptible to picking up moisture along the route, resulting in a wet nose.

Temperature Control

Because of their fuzzy coats, dogs do not have sweat glands distributed evenly over their whole bodies as we do. Instead, they regulate their body temperature by breathing heavily in hot conditions and sweating via glands located in the soles of their feet and at the tip of their nose, making their nose moist.

Even though it is typically a positive sign when a dog has a wet nose, you should still pay attention to whether or not it is too runny. A wet nose helps but needs a controlled temperature and moisture level. For example, excessive nasal discharge may indicate a more severe problem, such as an upper respiratory tract infection. Talk to your local veterinarian if you believe this to be the case.

What Does It Mean When A Dog has a Wet And Dry Nose?

Because the scent particles adhere more strongly to the nose when it is chilly and damp, a dog’s sense of smell is enhanced when the nose is under these conditions. If, on the other hand, you notice that your dog’s nose is warm and dry, you should not freak out since this condition might have several causes.

There are various situations where an otherwise healthy dog could have a drier nose. The moisture in the nose varies throughout the day and may sometimes be less dense than at other times. It is likely to be dry at home, particularly in the areas where dogs will not be sniffing or exercising to their full capacity.

They don’t lick their noses when they sleep, so their noses are usually dried and cracked when they wake up. In addition, if they are in a cooler home than usual, they may not be sweating as much, which would mean that their nose is more likely to stay dry.

Veterinarians have concluded that the amount of moisture in your dog’s nose does not impact whether or not she is ill. Some dog breeds have naturally drier noses than others, while other dog breeds have naturally wetter noses than others. This is because some dog breeds cannot reach their nostrils as effectively as others. Therefore, the notion that a dog’s dry nose indicates the disease is nothing more than an urban legend.

In conclusion, a healthy dog’s nose may be either dry or moist to address the issue. It is dependent on their degree of activity, the environment they are in, the way they behave, and various other things. Therefore, it is reasonable to believe that your dog is healthy as long as they have no other apparent signs of illness and its nose does not seem abnormally dry or moist.

You may be wondering, “Why do dogs lick their noses?” even though it is pretty reasonable to assume that dogs’ snouts would get moist due to their licking. A few different factors may explain the conduct in question.

A dog’s nose is prone to be soiled rather quickly, particularly when the animal is busy digging in the yard or devouring its meal. Dogs will lick their noses to keep their snouts clean. The previously stated mucous is the second reason why dogs lick their noses. Dogs do this for several reasons.

First, when your dog investigates different odors, his nose will pick up compounds that are associated with those odors. Then, your dog will lick off these compounds so that the olfactory glands on the roof of his mouth may sample them. This will help improve your dog’s ability to smell.

Another factor contributing to the wetness is that dogs sweat via their noses, which contributes to the dampness. They don’t sweat as much as humans do all over their bodies, thus keeping them cool in addition to the sweat from their paws. Other wet things: Our dogs have a habit of sticking their noses in damp spots.

Both the pad on top of the snout and the pads on the bottom of the feet are the only areas on a dog’s body where they can sweat; hence, this cooling mechanism (together with panting) might be vital to them when the temperature is high. In addition, our canine companions have a habit of often licking their noses, which, like those who lick their lips, tends to keep their noses wet.

In contrast to humans, dogs sweat from several different regions of the body, only perspiring via their noses and paw pads. Because of this secretion, your dog’s nose is often frosty and damp, even though it does not sweat in the traditional sense of attempting to cool off. However, the paw pads do produce sweat as a means of cooling the animal’s body temperature.

With the naturally occurring bacteria on your dog’s skin, this excretion is why many people claim that their dog’s paws smell like Fritos. So let’s say something about the chemical mix that smells like maize.

It is natural, but if it suddenly arises or changes abruptly, it may be a clue that something is awry in your dog’s body chemistry. Keep a close watch on it, and if it lasts more than a few days, make an appointment with your veterinarian.

Final Words – Why Are Dogs Noses Wet?

It’s not always so cut and white, we consider a wet nose a sign of good health, and a dry nose might indicate the complete opposite. For example, a dog in good health may have a dry or moist nose, but a nose that is sick may become either too dry or very wet. So be on the watch for alterations like this one since they might serve as excellent early warning indicators that your dog’s health isn’t as good as it should be.

However, it is essential to keep an eye out for other changes since a dry or moist nose does not always signal good health on its own.

If you notice that your dog has a dry nose, you should know that this condition is most likely nothing to be concerned about. It would be best if you did not base your dog’s overall health on the state of its nose; this is not an accurate indicator. This notion is that having a runny, cold nose is a sign of good health; therefore, there is no longer any basis for believing it to be true.

Sometimes a dry nose might be a sign of a more significant disease, and in these cases, it is quite probable that other symptoms will also be present. So, for example, if your dog is exhibiting signs of sickness, you should make an appointment with a veterinarian as soon as possible.

You should be mindful of how your dog’s nose smells, but if your dog appears normal in every other way, you shouldn’t have anything to worry about.
