Hi,

This sounds like Tracheal problems such as irritation or a collapse during times of excitement or exercise. This is a common condition in pugs, and often a previous medical condition such as Kennel Cough or a Upper Respiratory Illness can bring this on. I suspect that it is not the kennel cough that is persistent but instead tracheal collapse which has stemmed from the original infection.

Tracheal collapse is a condition in which the trachea partially collapses as a dog breathes, leading to tracheal irritation, coughing and sometimes secondary changes in the lungs or upper airways.

The irritation is self perpetuating, since coughing and increased respiratory efforts lead to further irritation and worsening of clinical signs. Eventually, damage can occur to the lungs, larynx or even upper airways. Obesity, irritants, allergies, concurrent heart failure, bacteria, viruses can all contribute to the problem, as well.

The symptoms of tracheal collapse are coughing, difficulty breathing and tiring easily. When this condition first occurs many dog owners truly believe that there must be something caught in their dog's airway due to the severity of the cough. If the tracheal collapse is occurring inside the chest the increase in pressure on the circulation can lead to heart enlargement or contribute to heart failure.

There are medical treatments for collapsing trachea as well as surgical treatments. The consensus of opinion seems to be that collapsing tracheal problems are best treated medically until it becomes obvious that medical treatment alone is not going to work.

 

What I would recommend is you set up a appointment with your vet to have the tracheal examined to determine how bad it is and how they want to proceed with treatment.
