Why is My Dog's Nose Dry

It is a common myth that a cold, wet nose signals a healthy dog. Therefore, many believe that they are sick when their nose is dry. Is it true?

Why Is Your Dog's Nose Always Wet

Your dog's nose secretes mucus. The inner lining contains special glands to produce mucus and keep the nasal canals moist. This thin layer of mucus clings to the nostrils and helps to enhance the absorption of chemicals and improve their ability to smell.

Dogs also constantly lick their nose to keep them clean since their noses always get dirty and they have to keep it clean and enhance their smell. They also lick their nose to gather scent particles inside their mouth.

Common Reasons Your Dog's Nose is Dry

He is Dehydrated

When we workout we stress a lot. The same goes to your furry friend. If you've taken them out for a run they will get dehydrated at some point. His nose will let you know that they need water.

Once they are rehydrated, their nose will be back to its moistened state.


Dogs can suffer from allergies too just like humans and these cause their noses to dry out. Dogs can have skin-related allergies, food-related allergies, and environmental-related allergies.

It's Their Breed

Dog's with short noses such as Bulldogs and Pugs often have difficulty licking their noses. They are prone to blocked air ducts which can also cause their nose to dry out.

Exposure to Elements

The wind and the sun can dry out your dog's nose much like our lips can dry out in the same conditions. This is temporary, but prolonged exposure to extreme temperatures can have adverse effects.


Older dogs are much more likely to have drier noses compared to younger ones. It just comes with age and there is nothing to worry about.

Autoimmune Disease

In the worst-case scenario, if your dog's nose is dry it is because of an autoimmune disease. The most common autoimmune disease that can cause their nose to dry is Lupus and Pemphigus. These diseases change the surface of your dog's nose resulting in cracking, dryness, and bleeding.

Treatment and Prevention of Dry Nose

When your dog's nose is dry, it will often resolve quickly on its own. But if your dog often has a nose dry nose, here are some things you can do to keep it wet.

  • Make sure they have access to clean, fresh water to keep them hydrated.
  • Apply dog-safe sunscreen to his nose to prevent sunburn.
  • Dog-safe balm can provide extra hydration. These are available through your pet supply stores or veterinarian.

When Should I Be Concerned About My Dog's Dry Nose?

Your dog's dry nose may only be temporary and it doesn't always mean a medical emergency. However, if there are other symptoms with the dry nose such as excessive mucus coming from your dog's nose, discolored gums, excessive coughing or sneezing, or an all over warm body temperature then you need to go to the vet as soon as possible to get them treated.
