Therapy for heart disease in such patients will not result in resolution of the cough, which instead should be treated with anti-tussives and bronchodilators. The cough reflex may also be triggered by repeated local trauma or stretch, such as might occur in dogs with structural abnormalities such as collapsing trachea or compression of the left mainstem bronchus. ). A study indicated that many dogs with collapsing trachea also have concurrent liver disease. To provide the best experiences, we use technologies like cookies to store and/or access device information.

The lack of complete rings, although beneficial for movement, can lead to loss of support and the potential for intermittent tracheal narrowing or collapse, particularly when stressed with cough or respiratory distress. Two classes of bronchodilators are widely used: methylxanthine derivatives and beta 2 agonists. For management, it is unclear whether clients or veterinarians can help prevent progression, with the exception that weight loss will decrease cough in overweight dogs. Based on in vitro enzyme kinetics data, it is believed that the non-linear kinetics may be partially associated with saturation of the low capacity enzyme (CYP2D15). Sudden opening of the glottis results in rapid expulsion of air under considerable pressure, which assists in removal of debris, foreign material, and mucus from the respiratory tract. The vet diagnosedcollapsing trachea. Cerenia Dosage and Administration Cerenia Tablets are recommended for use in dogs 16 weeks and older.

Clinically, a productive cough sounds moist and low-pitched, and the animal often swallows immediately afterwards. Tracheal collapse may affect the cervical, thoracic inlet, or intrathoracic trachea, and the disease may progress over time, resulting in additional areas of collapse. Some clinicians advocate gentle pressure on the trachea to induce a cough, which may or may not help confirm a diagnosis.

Despite resolution of the airway obstruction, some dogs continue to cough after stent placement, which may be frustrating for clients who had hoped the procedure would be curative.
