Dogs get kennel cough by inhaling airborne bacteria or viruses into their respiratory tract, which causes inflammation of the larynx and trachea. The infection is highly contagious and spreads easily in places where dogs congregate closely, such as boarding kennels, rescue centers, doggy daycares, grooming facilities, dog parks, and training classes
. The primary pathogens causing kennel cough include the bacterium Bordetella bronchiseptica and viruses such as canine parainfluenza and adenovirus type 2. These infectious agents are transmitted through airborne droplets when an infected dog coughs or sneezes, direct contact like touching noses, or by contact with contaminated surfaces such as toys, food, or water bowls
. Factors that increase the risk of dogs contracting kennel cough include:
- Exposure to crowded or poorly ventilated environments (e.g., kennels, shelters)
- Cold temperatures and environmental irritants like dust or cigarette smoke
- Stress from travel or changes in environment
In summary, dogs get kennel cough primarily through inhaling infectious airborne particles or contact with contaminated surfaces in environments where many dogs are in close proximity
