Why does a dog start coughing when it barks? - briefly

When a dog starts coughing while barking, it is often due to irritation or inflammation in the respiratory tract caused by conditions such as kennel cough or tracheal collapse. This can be exacerbated by the increased pressure and effort associated with barking.

Why does a dog start coughing when it barks? - in detail

When a dog starts coughing while barking, it can be indicative of several underlying conditions that affect the respiratory system or the throat area. The most common reasons for this phenomenon include:

  1. Tracheal Collapse: This condition is often seen in small breeds and occurs when the cartilage rings in the dog's trachea (windpipe) weaken and flatten, causing partial obstruction of the airway. When the dog barks or gets excited, it may trigger a coughing episode as the weakened trachea struggles to handle increased pressure.

  2. Kennel Cough: Also known as infectious tracheobronchitis, kennel cough is a highly contagious respiratory disease caused by various bacteria and viruses. It leads to inflammation of the dog's voice box and windpipe, resulting in a persistent, hacking cough that worsens with activity or excitement, such as barking.

  3. Heart Disease: In some cases, a cough while barking can be a sign of heart disease. When the heart is not functioning properly, fluid can accumulate in the lungs, leading to a condition called pulmonary edema. This causes shortness of breath and a dry or moist cough that may worsen with physical exertion or excitement.

  4. Throat Irritation: Various irritants such as smoke, dust, or allergens can cause inflammation in the dog's throat and airways. This can result in a persistent cough that is aggravated by barking, which increases the pressure on the affected areas.

  5. Foreign Bodies: Sometimes, a dog may ingest or inhale a foreign object that lodges in the throat or airway. This obstruction can lead to persistent coughing, which worsens with activities like barking that require increased breathing effort.

Regardless of the cause, it is crucial for pet owners to recognize that a cough while barking is not a normal occurrence and warrants immediate veterinary attention. Early diagnosis and appropriate treatment can help manage or resolve the underlying condition effectively.
