Why Is My Dog's Nose Wet?

The most common reason why your pup's nose is wet is because of the natural production of mucus and saliva in their body. This combination helps to keep the nose moist and helps to pick up scent particles in the air.

Another reason why your pup's nose may appear wet is because they are licking it. Dogs lick their noses to clean them, as well as to detect scent particles in the air. If you notice your pup licking their nose multiple times throughout the day, it could be a sign that they are picking up a scent.

What Is a Wet Nose?

A wet nose is a combination of mucus and saliva that helps to keep a dog's nose moist and helps to pick up scent particles in the air. The wetness of a dog's nose is essential for their sense of smell and keeping them cool.

Dogs have an incredible sense of smell, up to 10,000 times stronger than that of humans, and a wet nose helps them to pick up scent particles in the air.

A wet nose is also essential for keeping a pup cool. Dogs don't sweat like humans do, so their wet nose helps with heat regulation. The moisture from a wet nose helps to cool the pup down, just like when you wet your face with water on a hot day.

How a Dog's Nose Stays Wet

Healthy dogs have wet noses. But how do they stay that way? There are a few things a dog's body does to keep their noses wet.

  • Dog noses secrete mucus. There are special glands inside a dog's nose that secrete a thin layer of mucus that lines the inside of the nostrils.

There are special glands located on the inside of a dog's nose that produce mucus. By clinging to the dog's nose, this mucus increases how many scent particles the dog's nose picks up and subsequently improves their sense of smell.

Since a dog's nose is always coated in mucus, their body's cooling process is also improved through the evaporation of fluid.

  • Dogs lick their noses to keep them covered in saliva. Licking also serves to keep a dog's nose clean. Some dogs are better at this than others. if your dog doesn't lick their nose frequently or has difficulty reaching it, you may find your dog has a dry nose.

Dogs who lick their noses also transfer smell particles to the inside of their mouths, which further improves their ability to smell. An organ located in the roof of the mouth called the Jacobsen's organ allows them to gain extra information from scents.

Since a moist nose is critical to a dog's sense of smell, dogs quickly learn to keep their noses wet or to moisten them when they have a dry nose.

  • Environmental moisture levels also play a role in keeping a dog's nose wet. Working dogs pick up extra moisture from grass, leaves, plants, and puddles to keep their noses wet and their smell in tip top shape.

The Role of a Dog's Nose in Heat Regulation

A wet nose is essential for keeping a pup cool. Dogs don't sweat like humans do, so the moisture from a pup's wet nose helps to cool them down. The moisture from a wet nose helps to evaporate and cool the pup down, just like when you wet your face with water on a hot day.

The canine respiratory system is vastly different from that of humans, and plays a major role in regulating a dog’s body temperature. Compared to humans, dogs have relatively larger nasal passages, which are directly linked to the throat via a large void inside the skull called the nasal chamber. This nasal chamber allows air to circulate freely – it's part of the reason why dogs can smell so strongly, and also serves to regulate body temperature.

Hot air flows from the nasal chamber and into the mouth, where it’s expelled via panting. Dogs are also able to sweat through their paw pads, but this only accounts for around 10% of the body’s total heat loss. The remaining 90% is removed via the nasal chamber.

The Role of a Wet Nose in Scent Detection

A wet nose is essential for a pup's sense of smell. A pup's wet nose helps to pick up scent particles in the air and helps them to identify different smells. The moisture from a pup's wet nose helps capture and stick to tiny scent particles in the air, which helps them to identify different smells.

The wet nose amplifies a pup's sense of smell. The moisture from a pup's wet nose helps to amplify the scent particles, which helps them to identify different smells more easily. Since dogs use smell to get around in the world, the ability to smell things is crucial. Wet noses work better than dry ones because scent particles stick to their nose better.

A Wet Nose from Licking

Dogs lick their noses to help them detect scent particles. When a pup licks their nose, it helps to bring the scent particles closer to their nose, which helps them to identify different smells. Licking also helps to keep a pup's nose clean and healthy.

Is A Dry Nose A Sign of Illness?

A dry nose is not always a sign of illness, but it can be. If you notice that your pup's nose is dry and it persists for a long period of time, it could be a sign of dehydration or illness. If you notice that your pup's nose is dry for more than a few hours, it's best to take them to the vet to get checked out.

That said, a dry nose is not the best indicator of a health problem, nor is a wet nose an indicator of a healthy dog. Some perfectly normal, healthy animals have dryer noses than others.

Some dogs have drier noses as they age. A dry nose can also occur due to sun exposure and hot, dry weather. Assuming that your dog is cool and properly hydrated, this isn't anything to worry about.

What Your Dog's Nose Tells You About Their Health

While many believe that cold, wet noses indicate health, this isn't true. Dog noses change temperature constantly throughout the day. Since they play a role in temperature regulation and keeping your dog cool, a hot nose may simply indicate your dog is hot.

In contrast, very sick dogs can still have a moist nose that feels cool to the touch, so a wet dog nose is not the best indicator of health status.

While a wet nose or dry nose won't tell you much about your dog's health by itself, there are other signs exhibited by dog noses that can.

  • Nasal discharge that resembles clear fluid is normal. It occurs due to irritation in the nasal passage - usually from environmental irritants like pollen, perfume, or smoke. Nasal discharge that's thick, bloody, or colored can indicate an injury or respiratory infections.
  • Changes in pigmentation of a dog's nose, particularly scaling or open sores can be an indication of illness.
  • Brachycephalic dogs tend to be at higher risk of respiratory infection than dogs with long snouts as they are less able to clear irritants from their nasal passages.

How To Keep Your Dog's Nose Healthy

Keeping your pup's nose healthy and moist is essential for their sense of smell and overall health. Here are some tips to keep your pup's nose healthy:

  • Make sure your pup is getting enough water. Dogs need plenty of water to stay hydrated and to keep their noses moist.
  • Use a pet-safe moisturizer for your pup's nose. There are a variety of pet-safe moisturizers on the market that can help to keep your pup's nose moist and healthy.
  • Clean your pup's nose regularly. Use a damp cloth and pet-safe cleaner to clean your pup's nose regularly. This will help to keep it clean and healthy.
  • Avoid over-washing your pup's nose. Over-washing your pup's nose can dry it out and make it more prone to cracking and irritation.
