Kennel Cough in Dogs
If your
dog is hacking away or constantly making noises that make it sound like he's
choking on something, he may have a case of
kennel cough, or canine infectious tracheobronchitis. Although kennel cough can sound terrible, most of the time it is not a serious condition, and most dogs will recover without treatment.
What is kennel cough?
Just as human colds may be caused by many different viruses, kennel cough itself can have multiple causes. One of the most common culprits is
Bordetella bronchiseptica bacteria, which is why many people use the terms kennel cough and bordetella interchangeably. Most dogs that become infected with bordetella bacteria are infected with a virus at the same time. These diseases, which are known to make dogs more susceptible to contracting bordetella infection, include canine adenovirus, canine
distemper virus, canine herpes virus, parainfluenza virus and canine reovirus.
Dogs "catch" kennel cough when they inhale bacteria or virus particles into their respiratory tract. This tract is normally lined with a coating of mucus that traps infectious particles, but there are a number of factors that can weaken this protection and make dogs prone to kennel cough infection, which results in inflammation of the larynx (voice box) and trachea (windpipe).
These factors include:
Exposure to crowded and/or poorly ventilated conditions, such as are found in many kennels and shelters
Cold temperatures
Exposure to dust and/or cigarette smoke
Travel-induced stress
Symptoms of kennel cough
The classic symptom of kennel cough is a persistent, forceful cough. This is distinct from a cough-like sound made by some dogs, especially little ones, which is called a reverse sneeze. Reverse sneezes can be normal in certain dogs and breeds, and usually only indicates the presence of post-nasal drip or a slight
irritation of the throat.
Some dogs with kennel cough may show other symptoms of illness, including
sneezing, a runny nose, or
eye discharge.
If your dog has kennel cough, he probably will not lose his appetite or have a decreased energy level.
Treating and preventing kennel cough
Kennel cough is contagious. If you think your dog might have the condition, you should keep him away from other animals and contact your veterinarian.
Although most cases of kennel cough will resolve without treatment, medications may speed recovery or minimize symptoms during the course of infection. These include
antibiotics that target the bordetella bacteria and cough medicines.
You may also find that keeping your dog in a well-humidified area and using a harness instead of a collar, especially for dogs that strain against a leash, will minimize the
coughing.
Most dogs with kennel cough recover completely within three weeks, though it can take up to six weeks in older dogs or those with other medical conditions. Because serious, ongoing kennel cough infection can lead to
pneumonia, be sure to follow up with your veterinarian if your dog doesn't improve within the expected amount of time. Also, if your dog at any time has symptoms of rapid breathing or listlessness, contact your vet right away, as these could be signs of more serious conditions.
Treating and preventing kennel cough continued...
There are two forms of vaccine for kennel cough, one that is injected, and one that is delivered as a nasal mist. Although these
vaccines may help, they do not guarantee protection against kennel cough or infectious tracheobronchitis because it can be caused by so many different kinds of bacteria and viruses. Also, it is important to realize that neither form of the kennel cough vaccination will treat active infections.
The injected form of the kennel cough vaccination is typically used for dogs that are likely to bite. Puppies typically receive two doses initially, about four weeks apart, followed by yearly booster shots.
The intranasal kennel cough vaccination is typically given to dogs once a year, but may be recommended to be given every six months for dogs at high-risk for kennel cough. This form of the vaccine tends to provide dogs protection against kennel cough sooner than the injected shot.
