If your dog has suddenly developed a persistent hacking cough, you’re not alone.
Over recent weeks, veterinary clinics have seen a noticeable increase in cases of kennel cough, leaving many owners concerned about what is causing their dog’s symptoms.
Kennel cough (also known as canine cough) is a contagious upper respiratory infection in dogs caused by several different highly infectious bacteria and viruses, most commonly Bordetella bronchiseptica. Much like the common cold in people, it is highly contagious and spreads easily wherever dogs come into contact with one another.
Despite its name, dogs don’t have to visit a boarding kennel to catch kennel cough.
It can be picked up almost anywhere dogs socialise, including dog parks, or even during a walk where dogs greet each other. The infection spreads through airborne droplets produced when an infected dog coughs or sneezes, as well as contaminated bowls, bedding, toys and other shared surfaces.
The most common symptom is a harsh, dry, hacking cough that often sounds as though your dog has something stuck in their throat. Many dogs will gag or retch after coughing, while others may sneeze or develop a mild runny nose. Excitement, exercise or pulling on a lead can make the coughing worse, and some dogs cough so forcefully they vomit.
Most otherwise healthy dogs remain bright, active and continue eating normally despite their cough. Symptoms usually appear three to seven days after exposure and often improve within one to two weeks. However, not every cough is kennel cough.
A cough can also be a sign of more serious conditions including pneumonia, heart disease, collapsing trachea, airway obstruction or, in some regions, heartworm disease. For this reason, any persistent or worsening cough should be assessed by your veterinarian. A physical examination, and in some cases blood tests or chest x-rays, may be recommended to determine the underlying cause.
Treatment depends on the severity of the infection. Many mild cases simply require rest, avoiding strenuous exercise and allowing time for the airways to heal. More severe infections may require medication, particularly if there are signs of secondary bacterial infection or pneumonia.
Vaccination remains the best way to reduce your dog’s risk. Vaccines are available and help lessen both the severity of illness and the spread of infection. While no vaccine offers 100 per cent protection, vaccinated dogs generally experience much milder disease.
If your dog develops a cough, keep them away from other dogs until they have recovered, as kennel cough spreads very easily. Early veterinary assessment not only helps your own dog recover but also reduces the risk of passing the infection on to others.
