Infectious tracheobronchitis (kennel cough) is a highly contagious disease of the canine respiratory tract. The germs associated with this disease infect the cells lining the interior of the trachea (windpipe) and the bronchi (large air passages of the lungs). The disease is usually caused by a virus which develops into a bacterial infection.
Signs appear 8-10 days after the dog catches the disease. A harsh, dry cough often followed by gagging and coughing up foamy mucous are the most common signs of kennel cough. Any type of excitement or physical exercise triggers the cough which can be so hard that the owner thinks that an object is caught in the throat. This disease is extremely contagious for dogs, but does not affect humans.
Exposure to kennel cough often occurs at dog shows, grooming parlors, and boarding kennels. Vaccinations are available to protect against the disease. Bordatella bronchiseptica vaccine is recommended for dogs that board at kennels or are exposed to highly social environments. Consult with your veterinarian for the vaccination protocol that is best suited for your dog.
