General
Information
Infectious
tracheobronchitis (canine cough or kennel cough) is the
name given to a 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 (parainfluenza or adenovirus
type 2) associated with an infectious bacteria (Bordetella
bronchiseptica). Other viruses have been incriminated in
the disease along with bacteria-like organisms called mycoplasms.
Viruses, being extremely contagious,
are responsible for the initial phase of the disease. Bordetella
bronchiseptica, the secondary invader, is associated with
the severe, pronounced symptoms.
A harsh, dry cough often followed
by gagging are the most common signs of kennel cough. Any
type of excitement or physical exercise triggers the cough.
The dog often coughs so hard that the owner thinks that
an object is caught in his throat. Most dogs with the uncomplicated
form of kennel cough do not have a fever.
This disease is extremely contagious
for dogs. It does not affect humans. The name “kennel
cough” comes from the notion that dogs boarded in
kennels are more likely to contract the disease. This is
due to the high concentration of dogs, the stress, and the
nose-to-nose
contact.
As long as the dog appears healthy,
is eating well, and the cough is not too severe, a trip
to veterinarian may be delayed. If the cough persists or
the dog begins to show other symptoms, a visit to the veterinarian
is necessary.
Infectious tracheobronchitis is extremely
contagious and dogs with the disease should be isolated
from healthy dogs. If your dog has kennel cough, rest is
very important. If a dog with kennel cough is worked too
hard, pneumonia can easily develop.
Exposure
to canine cough often occurs at dog shows, grooming parlors,
and boarding kennels. Modern vaccinations are available
to protect against the disease. Intranasal Bordetella bronchiseptica
vaccine is recommended for dogs that board at kennels. Consult
with your veterinarian for the vaccination protocol that
is best suited for your dog.
