French bulldogs are energetic, fun-loving, and always a joy to be around. However, if you’re around them for long enough, you’ll know they often suffer from runny noses. French Bulldogs are predisposed to having a greater rate of nasal discharge than other dog breeds. This is due to their flat face and compressed nasal passages that this dog breed has inherited from its ancestry. As a Frech Bulldog owner, you should be on the lookout to make sure that most of the nasal discharge is minor, and won’t cause any long-term health issues. If you notice any blood or pus coming from their nose, you should take your dog to the veterinarian right away.

French Bulldogs are prone to developing these symptoms:

1. They get very energetic

If you notice the French Bulldog has a runny nose while playing, but their symptoms clear up when they stop, that’s a good sign. But if your Frenchie’s nose is still running after a few hours of no heavy activity, then you should be concerned.  If the discharge is not colored and shallow, there should be no concern if it does not smell.

2. They have nasal infections

French Bulldog owners who notice a heavy nasal discharge that smells strong and is yellow, green, or white in color should be aware of the possibility of dog nose infections. It’s a good idea to head down to the local veterinarian’s office for them to get checked out.

Common signs of a sinus infection include:

·        Canine Distemper: thick like glue and yellow-green in color.

·        Parainfluenza: A cough that persists and won’t go away.

·        Aspergillosis: A fungal disease that attacks dogs with a weak immune system.

·        Dog Flu: The symptoms are difficulty breathing, weakness and lethargy, fever and a cough.

3. Allergies

French Bulldogs are prone to allergies in the same way that humans are. They often suffer from them during the Summer months due to increased pollen production or if they’ve recently moved. If your French Bulldog has allergies, then you’ll observe a runny nose with a clear and odorless discharge.

4. Blocked nasal passage

French bulldogs can have runny noses if their nasal passages are blocked/obstructed. If they have a lot of mucus discharge coming out of one nostril and hardly any from the other, there’s a good chance something is stuck up their nose. To support your dog’s examination, notice that a nosebleed is occurring. Nosebleeds happen when the nasal passage becomes blocked and it will cause sneezing or your dog may be trying to itch that side of the nose to get rid of the problem. If you notice that your dog has something stuck in his nose, call the vet right away.

5. Nasal tumors

If your dog suddenly seems to be having trouble breathing and they have mucus or blood in its nose, it might be experiencing nasal tumors or polyps. If your dog suddenly loses his appetite and you can see small swellings against the side of their nose, then get him to a vet as quickly as possible.

6. Cleft palates

Cleft palates commonly affect French Bulldogs. This splits the dog’s mouth and divides his nasal passages. Water, food, and germs are easily able to get into the nasal cavity which allows infections to grow. Be aware of water discharging from your dog’s mouth with bits of food in it, especially after the dog drinks or eats.

7. Breeding issues

French Bulldogs have extremely small nasal passages as a result of their unique appearance. This, however, makes them more prone to respiratory distress and thickened nasal discharge, which is troublesome for both the dog and its owner. It’s important to take your dog to the veterinarian if you notice their nose is runny for a long time and they aren’t getting better. Some Frenchie mixes unfortunately do suffer from these nasal problems, but we have found that the harness helps to minimize these issues.


There are many reasons your French Bulldog could have a runny nose. You should always be diligent and observe your dog for signs of illness or infection, and you should never wait before taking them in to see the ve
