A severe and chronic cough in a dog can indeed be attributed to Bordetella, which is often responsible for kennel cough, a highly contagious respiratory disease. Bordetella bronchiseptica, the bacterium involved, causes inflammation of the trachea and bronchi, leading to a characteristic harsh, dry cough that can persist over time and may worsen with exertion or excitement.

In addition to the cough, affected dogs might show other signs, such as nasal discharge, lethargy, and fever, indicating that the cough is not just an isolated symptom but part of a broader respiratory issue. It's important for pet owners to be aware that Bordetella can spread easily among dogs in close quarters, such as shelters or boarding facilities.

While other conditions like fungal infections, canine distemper, and heartworm disease can also cause coughing, they tend to be associated with a range of other symptoms and may not primarily manifest as a chronic cough. For instance, heartworm disease would typically present with symptoms related to cardiovascular issues as well, and distemper would show additional neurological signs. Understanding the specific characteristics and contexts of these diseases helps highlight why Bordetella is strongly linked to cough in canines.
