While dogs do not get sick the same way we do, they can catch viruses and other infections. 

There are, unfortunately, other more sinister reasons behind a runny nose and it is a good idea to know of the many other underlying causes of runny noses in dogs.

It is important that pet owners beware of serious problems that can be the reason behind their pup’s runny nose that are much more concerning than a passing allergy or cold.

There are many possible causes for a dog’s runny nose. While many of the causes for a dog’s runny nose are mild, some are more serious.

Allergies

Symptoms of allergies in dogs:

  • Itching
  • Red and inflamed skin
  • Ear infections
  • Excessive grooming or licking along with excessive panting
  • Digestive issues
  • Anxiety
  • Eye discharge
  • Reverse sneezing
  • Clear discharge out of the nose 

Dogs can be affected by seasonal allergies, food allergies, or allergens in the dog’s environment. 

Your vet may recommend performing an allergy test or elimination diet with your dog. The best way to decrease allergic reactions is by removing the allergen, but this can be tricky.  

Infections

There are many infections that can affect our dogs. They include bacterial infections, viral infections, or bacterial infections. 

Each of these infections will need different treatment options, so seeking veterinary care if your dog presents any of these symptoms is important for your dog’s health.

Common symptoms of an infection or the dreaded dog cold

  • Cold symptoms
  • Lack of appetite
  • Severe runny nose with a bad odor and thick, green, or yellow nasal discharge
  • A high body temperature
  • Bloody nose
  • Noisy breathing (common in upper respiratory infections)
  • Decreased energy levels

Common causes of infections in dogs

  • Kennel cough
Some other causes include:
  • Canine adenovirus
  • Canine distemper virus
  • Canine influenza viruses
  • Canine herpesvirus
  • Canine parainfluenza virus
  • Bordetella bronchiseptica
  • Streptococcus Equi subspecies zooepidemicus
  • Mycoplasma spp
  • Parasitic nasal mites

Nasal mites are parasites that live in dogs’ nasal passages and sinuses.


Symptoms include:

  • Nasal discharge
  • Bloody discharge from the nose or full nose bleeds
  • Sneezing
  • Loss of smell
  • An itchy face, especially around the nose
  • Head shaking
  • Nasal aspergillosis 

Nasal aspergillosis is a fungal infection that can be seen as a runny nose. On the side of the nose, there are usually sores present as well. 

Your vet will need to perform an endoscopy or even a CT scan to confirm the diagnosis. 

  • A foreign object in your dog’s nose

Dogs are inquisitive, and because of this, they are prone to getting things stuck in their nose. This is a very common reason for a runny nose in a dog. 

Make sure to get your dog looked at as quickly as possible. If a foreign object is left in for too long, it can cause an infection.

Treatment and Outlook

The method of treatment is going to vary depending on why your dog has a runny nose, but thankfully, most of the time a slightly runny nose is not a major cause for concern. 

The best thing to do is to follow your veterinarian’s instructions and keep a close eye on your dog. 

Using a journal to track symptoms may be helpful in dogs with allergies. Most infections can be cleared up effectively with treatment. 

Your vet will be able to make a wise decision for treatment for your dog.  

It is important to always consult with your veterinarian. Please keep in mind that we are NOT veterinarians, but we do conduct thorough research.
