Bordetella refers to the bacterial agent Bordetella bronchiseptica, which is the most common cause of kennel cough in dogs. Kennel cough, scientifically known as canine infectious tracheobronchitis, is a highly contagious respiratory illness that can be transmitted through aerosol droplets, direct contact, or contaminated surfaces. Symptoms of kennel cough include a persistent honking cough, runny nose, sneezing, loss of appetite, lethargy, and low-grade fever. Vaccinating against Bordetella is necessary to prevent the spread of kennel cough and protect dogs in communal settings.
