Seeing your dog breathing heavily while also having a runny nose can be alarming. These symptoms may signal anything from mild allergies to serious respiratory illnesses.
We outline the possible causes of heavy breathing and running nose in dogs, what you can do at home, and when to seek veterinary help.
Dog Panting Excessively and Shaking While Sleeping — Why It Happens
Heavy breathing with a runny nose in dogs often points to underlying issues affecting the respiratory system. Common triggers include respiratory infections, heart disease, nasal blockages, allergies, or even heatstroke.
While some cases resolve quickly, ongoing or severe symptoms should always be taken seriously and assessed by a veterinarian.

Allergies
Seasonal or environmental allergies can inflame the nasal passages, leading to a runny nose and heavier breathing.
Itching, watery eyes, and sneezing may also appear. Severe cases require medical intervention.
Heart Disease
Heart problems such as congestive heart failure can cause fluid buildup in the lungs and nasal passages.
Dogs may also cough, tire easily, or faint. This is a medical emergency.
Nasal Obstruction
Foreign objects, nasal tumors, or polyps can block airflow and cause nasal discharge.
The obstruction makes breathing harder, and gagging or sneezing may occur as the dog tries to clear it.
Heatstroke
Overheating can lead to rapid, heavy breathing and nasal discharge.
Other signs include drooling, weakness, and collapse. Immediate cooling and vet care are essential.
What to Do If Your Dog Is Breathing Heavily and Has a Runny Nose
Keep your dog calm and indoors in a comfortable environment.
Gently wipe away nasal discharge to help them breathe easier, but avoid inserting anything into their nostrils.
Ensure access to fresh water and monitor closely for worsening symptoms.
If symptoms persist beyond 24 hours or worsen rapidly, call your vet.
When to Call or Visit Your Vet
Contact your veterinarian right away if your dog’s symptoms are sudden, severe, or accompanied by coughing blood, blue gums, collapse, or extreme lethargy.
Even mild nasal discharge with heavy breathing should be checked if it lasts more than a day or two.
