Kennel cough or infectious canine tracheobronchitis is an infection of the
trachea, or windpipe that causes almost continual coughing. Most times this virus is spread indoors and usually will be found at animal shelters, pet shops, and boarding kennels.
If untreated, the cough will usually disappear on it's own although some coughers with poor appetites and lethargy may develop pneumonia and will have to be taken for treatment and medication to your vet. If not treated, the animal can die.
The Bordetella vaccine comes highly recommended if your dog will be exposed to other animals. The vaccine is available in injectable form and as an intranasal vaccine.
