What is kennel cough?
This common name refers to a group of contagious respiratory infections in dogs. Several agents may be involved, including Bordetella bronchiseptica and respiratory viruses. Close contact at day-care facilities, boarding kennels, parks and other shared spaces can make transmission easier.
Repeated dry coughing, sometimes followed by gagging, is a common presentation. Coughing has other possible causes, however, and does not confirm a diagnosis. Note when it began, whether there is nasal discharge or reduced appetite, and whether your dog recently had contact with other dogs; share this information with the veterinarian.
When to seek care
Arrange an assessment if your dog is coughing. Difficulty breathing, marked lethargy, bluish gums, collapse or rapid worsening require urgent in-person care. Puppies, older animals and dogs with other health conditions may need particular attention. Call the centre before arriving to help reduce exposure for other patients.
While waiting for advice, keep your dog away from other dogs. Do not give antibiotics, human cough medicines or leftover medication on your own. Treatment depends on the assessment, and not every cough needs the same medication.
What is the KC vaccine for?
Depending on exposure risk, history, product and boarding requirements, a veterinarian may recommend a respiratory vaccine. Formulations and routes of administration vary. No vaccine protects against every possible cause of coughing or replaces examination of a sick dog. If you plan to use day care or boarding, ask about its requirements in advance.
Reinavet offers the KC vaccine at home; ask whether the specific vaccine is available before booking. A scheduled visit does not replace emergency care.
