One of the most common questions that I am asked about dogs during the chilly winter months is whether or not our furry friends can catch colds and flu from people.

Although dogs and humans can pass a number of illness between one another, a phenomenon called zoonosis, the trading of colds and flu, is not found on this list.

However, it is important to know that even though dogs cannot catch colds from people, they still can develop a canine version of the cold known as tracheobronchitis. We humans refer to this ailment as kennel cough, and sick dogs usually exhibit a dry, hacking cough that may or may not be accompanied by a runny nose and fever.

There are several different types of viruses and bacteria that either alone or in combination can cause kennel cough. This vast array of strains means that under the right conditions even the toughest dog may be at risk. Like the common cold in people, kennel cough is more prevalent in places where there is a bigger doggie public. Where people commonly catch colds at school, the doctor's office, or on a plane, dogs can be exposed to germs at training class, the vet's office, or even at the Bowser bed and breakfast. Hence, the name: kennel cough.

Simple exposure to the illness does not guarantee that a dog will get sick. Like the common cold in people, dogs who are stressed or have a weary immune system are more likely to become ill. Some types of kennel cough are not dangerous at all, and the annoying coughing might go away on its own without any antibiotics. Unfortunately, other strains are very powerful and can become deadly in a relatively short period of time. Because of this, it is important to always have a coughing dog checked by a veterinarian. The good news is that with the right treatment, an ailing dog is sure to make a full recovery in about a week. The bad news is that, although now immune and seeming perfectly healthy, this same dog can shed the virus for several months thereby exposing other healthy dogs to the illness.

This is why the neighbor's dog who spends time at the dog park can spread the airborne disease to your dog who never leaves the yard.

This is also why eliminating kennel cough is a tail-chasing endeavor for pet professionals.

Fortunately, vaccination can protect your dog against many strains of the canine cold. The first immunity is administered in the form of nose drops that can be given as early as two weeks of age without interfering with the natural resistance to other diseases that the mother provides. After the initial treatment, a dog can then receive regular booster shots to maintain immunity.

Prevention is the best protection, so be sure to ask your veterinarian about vaccinating your dog against kennel cough.
