A PERSISTENT cough can be worrying for any dog owner, particularly when it seems to come on suddenly. Recently, veterinary clinics have seen an increase in dogs presenting with coughing, with kennel cough being one of the more common causes.

Despite its name, kennel cough is not limited to dogs that have stayed in a boarding kennel. Dogs can be exposed anywhere they come into contact with other dogs, including at dog parks, daycare, training classes or even while stopping for a friendly sniff during a walk.

Kennel cough, also known as canine infectious respiratory disease, is a highly contagious infection affecting the upper respiratory tract. It can be caused by a combination of bacteria and viruses, with Bordetella bronchiseptica being one of the most commonly involved bacteria. The infection spreads easily through droplets released when an infected dog coughs or sneezes. Dogs can also be exposed through shared items such as water bowls, toys and bedding.

The classic sign of kennel cough is a dry, harsh cough that can sound like a honking noise or as though something is caught in the dog’s throat. Some dogs will gag or retch at the end of a coughing episode, while others may sneeze or have a mild nasal discharge. Coughing may become more noticeable when a dog is excited, exercising or pulling against their lead, and occasionally the coughing can be severe enough to cause vomiting.

One of the frustrating things about kennel cough is that many affected dogs otherwise appear perfectly well. They may still be eating, playing and behaving normally despite their persistent cough. Signs commonly develop within several days of exposure and, in uncomplicated cases, often settle over one to two weeks.

However, it is important not to assume that every cough is simply kennel cough. Coughing can also be associated with a range of other conditions, including pneumonia, heart disease, collapsing trachea or an obstruction in the airway. Persistent, worsening or severe coughing should always be checked by a veterinarian. Depending on the individual dog and their symptoms, further investigations such as blood tests or chest X-rays may be recommended.

Treatment will depend on the severity and underlying cause of the cough. Mild cases of kennel cough may only require rest and time to recover, while more serious infections may need medication, particularly where a secondary bacterial infection or pneumonia is suspected.

Vaccination can help reduce the risk and severity of kennel cough and may also help limit its spread. While vaccination cannot guarantee complete protection, vaccinated dogs will often experience a milder illness.

If your dog develops a cough, it is important to avoid contact with other dogs until they have recovered. This helps protect other dogs from what can be a highly contagious infection.
