Symptoms
Symptoms are dry cough, sneezing, snorting, and a watery nasal discharge. Sometimes, they include vomiting and lethargy. Usually, the symptoms are observed after four to five days of exposure, and the illness may last for three weeks. Very young puppies and dogs with low immune systems are more prone to severe kennel cough. This condition is diagnosed based on the symptoms and physical examination. For confirmation, X-ray imaging, blood tests, and bacterial culture or viral isolation can be done.
