My Dog Has a Cough: Understanding Causes and Solutions

A coughing dog can be a cause for concern for many pet owners. While an occasional cough may not be a sign of serious illness, it's essential to understand the potential causes and when to seek veterinary advice. In this comprehensive guide, we'll explore why dogs cough, home remedies that might provide relief, and when it's crucial to consult a professional.

Understanding Canine Coughing

Just like in humans, coughing in dogs is a reflex designed to remove foreign objects, mucus, or irritants from the throat and airways. But why might your dog be coughing?

  1. Kennel Cough: Also known as Bordetella, this is a highly contagious respiratory disease. It's named for its prevalence in environments where many dogs congregate, like kennels and shelters.

  2. Heartworm Disease: Transmitted by mosquitoes, heartworms can live in the heart and pulmonary arteries, leading to coughing.

  3. Canine Influenza: Just like humans, dogs can catch the flu, resulting in symptoms like coughing, nasal discharge, and fever.

  4. Allergies: Dogs can be allergic to pollen, dust, mold, and other environmental factors, which can lead to coughing.

  5. Foreign Object: Inhaling or swallowing a foreign object can cause coughing as the dog attempts to dislodge it.

Home Remedies for Coughing Dogs

  1. Honey: A teaspoon of honey can soothe the throat and reduce coughing. Ensure it's pure and free from xylitol, which is toxic to dogs.
  2. Steam: If your dog is comfortable, allowing them to inhale steam from a shower can help open up the airways.
  3. Humidifiers: Adding moisture to the air can help alleviate coughs, especially if they're due to allergies.
  4. Fresh Air: Ensure your living space is well-ventilated. If indoor irritants are causing the cough, fresh air might help.

When to See a Vet

While occasional coughing can be addressed with home remedies, it's essential to recognize when professional help is required:

  1. Persistent Coughing: If the cough lasts more than a week or seems to be worsening.
  2. Other Symptoms: If coughing is accompanied by lethargy, difficulty breathing, blue gums, or loss of appetite.
  3. Known Exposure: If your dog has been in an environment with other coughing dogs, it's essential to get them checked.


A coughing dog can certainly stir concern. While there are measures you can take at home to alleviate symptoms, it's crucial to remain vigilant and seek professional advice when necessary. Your dog's health and comfort are of utmost importance, and understanding the causes and solutions to their cough is a step in the right direction.
