Occasionally, your canine companion may experience coughing and difficultly breathing. While this is often not a serious concern, certain coughs—especially if they are persistent—can indicate severe health issues that require veterinary care. Below are several reasons that your dog may be experiencing this issue, as well as some treatment options.

What Causes Dogs to Cough?

1. Sore Throat

When a dog has a sore throat, you may notice that the cough has a higher pitch than normal. This happens when bacteria gets into their windpipe and causes an infection, preventing air from passing through. Tonsillitis or sinusitis are the most common conditions that lead to a sore throat and minor coughing. Typically, antibiotics will eliminate the infection and restore normal breathing.

2. Tracheobronchitis

If your dog has a deeper cough that sounds like they are honking, this could be a result of tracheobronchitis. Also known as “kennel cough,” this contagious disease affects the upper air passages. While this is usually not serious, if the bacteria spread to the lungs, it can lead to chronic bronchitis or pneumonia. A veterinary care team can administer antibiotics to eliminate bacteria and remove infections before they spread.

3. Heart Disease

When a dog’s heart does not pump correctly, this is known as congestive heart failure. If your dog experiences this condition, fluid can accumulate in their lungs, preventing the canine from breathing correctly. You will notice a loud cough that resembles cackling or wheezing. This requires immediate attention from a veterinary care professional, as they can prescribe medication to regulate the heartbeat and slow the buildup of fluid.

4. Pulmonary Conditions

If it sounds like your dog is coughing up liquid, then phlegm and mucus are likely blocking their airway. This is one of the primary symptoms of pneumonia, and it is contagious. This condition is serious, requiring immediate care. A veterinarian can prescribe anti-inflammatory medication to reduce pain and fever, while an expectorant will loosen up mucus to assist with breathing.
