# Kennel Cough in Dogs — Quick answer

PETHEALTH+ (https://pethealth.org.uk/health/kennel-cough-in-dogs): Kennel Cough in Dogs — Quick answer. Kennel cough is a highly contagious upper respiratory infection that causes a harsh, honking cough, often triggered by excitement or pulling on the lead. Most dogs recover with rest in one to three weeks, but puppies, seniors, and brachycephalic breeds can develop pneumonia — contact your vet if breathing is laboured, appetite drops, or coughing persists beyond two weeks.

PETHEALTH+ (https://pethealth.org.uk/health/kennel-cough-in-dogs): Kennel Cough in Dogs — What is kennel cough?. Kennel cough — also called infectious tracheobronchitis — is not a single disease but a syndrome caused by several viruses and bacteria. The most common bacterial agent is Bordetella bronchiseptica, often working alongside viruses such as canine parainfluenza or canine adenovirus type 2. The name reflects how easily it spreads in places where dogs gather: boarding facilities, daycare, dog parks, grooming salons, and training classes.

PETHEALTH+ (https://pethealth.org.uk/health/kennel-cough-in-dogs): Kennel Cough in Dogs — How does kennel cough spread?. Infected dogs shed pathogens when they cough, sneeze, or bark. Transmission happens through: - Direct nose-to-nose contact - Shared water bowls and toys - Airborne droplets in enclosed spaces - Contaminated hands or clothing Incubation is typically three to ten days after exposure. A dog can be contagious before obvious symptoms appear.

The hallmark sign is a dry, honking cough that may sound like the dog is choking or gagging. Other signs include: - Sneezing and nasal discharge - Mild fever - Reduced energy or appetite - Retching after coughing (sometimes producing white foam) Most dogs remain bright and eat normally. Worsening signs — lethargy, thick green nasal discharge, rapid breathing, or blue-tinged gums — suggest complications such as pneumonia and need urgent care.

PETHEALTH+ (https://pethealth.org.uk/health/kennel-cough-in-dogs): Kennel Cough in Dogs — Diagnosis and treatment. Your vet usually diagnoses kennel cough from history and examination. Chest X-rays or bloodwork may be recommended if pneumonia is suspected. Treatment depends on severity: - Mild cases: Rest, a harness instead of a collar, and avoiding irritants like smoke or cold air - Moderate cases: Cough suppressants or anti-inflammatories as prescribed - Bacterial involvement: Antibiotics such as doxycycline - Severe cases: Hospitalisation with oxygen, IV fluids, and intensive monitoring Never give human cough medicines without veterinary guidance — many contain ingredients toxic to dogs.

The Bordetella vaccine reduces severity and spread but does not prevent all causes of kennel cough. Keep vaccinations current if your dog boards, attends daycare, or visits groomers. Avoid dog parks and group settings while your dog is coughing or for at least two weeks after symptoms resolve, as advised by your vet.
