The classic goose honking cough of tracheal collapse
The tracheal anatomy is supported by Cshaped rings of cartilage that are subject to degeneration and collapse. Often therapeutic trial will be elected prior to invasive or expensive tests, but this approach not be appropriate for all coughing dogs. The patients overall health history, potential exposure to rodenticides, and heartworm status will be quite important to their assessment. Dogs with bacterial pneumonia will usually have soft, productive cough that reflects the presence of mucus and purulent material within the airways. Harsh noises are more often associated with airway problems than with lung or cardiac problems.
Other dry coughs are associated with tonsillitis or tracheitistracheobronchitis, such as the familiar kennel cough. Collapse or narrowing of this area stimulates dry, harsh to honking cough that is also observed in patients with spontaneous collapse of the trachea or mainstem bronchi. The importance of patience Coughing not sound like serious problem, but sometimes it is sign of significant disease. Some dogs with nasopharyngeal disease cough, sneeze and reversesneeze, as well as gag or retch, making it challenging for the veterinarian to figure out exactly what the problem is.
If pleural fluid is present it be retrieved for analysis with needle introduced into the chest cavity. reverse sneeze is associated with noisy inspiratory and expiratory events without the big expiratory burst. particular dilemma is the chubby geriatric toy breed dog with collapsing trachea, mitral valve insufficiency and probable chronic bronchitis. The resulting cough frequently sounds dry or harsh, but is frequently associated with gagging or retching after the cough because of fluid within the airways. Mitral valve and tricuspid valve degeneration are exceedingly common among small to medium sized aging dogs.
Subtle changes in chest xrays or in response to medication changes will often direct the course of treatment. Unfortunately, the condition tends to progress, leading to sacculation and gross distortion of the bronchi termed bronchiectasis in some, or other irreversible changes in airway function or anatomy. The resulting cough frequently sounds dry or harsh, but is frequently associated with gagging or retching after the cough because of fluid within the airways.
Patients with lung cancer, systemic bleeding tendency, or severe inflammatory diseases also cough up blood. Coughs occurring because of allergic or cancerous conditions are frequently dry and nonproductive. Fiberoptic imaging will permit visualization of the airways and specific sampling of masses.
