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:
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.
