Dog Kennel Cough: Management and Prevention

Kennel cough is a highly contagious respiratory disease complex in dogs, spreading rapidly in group settings and requiring vaccination and isolation protocols.

Key Facts

Kennel cough (infectious tracheobronchitis) involves multiple pathogens including Bordetella bronchiseptica and canine parainfluenza
The hallmark dry, honking cough can persist for 2-3 weeks even with treatment
Most healthy adult dogs recover without treatment; puppies and elderly dogs face higher complication risk
Vaccination (intranasal or injectable) reduces severity but does not fully prevent infection
Transmission occurs through airborne droplets, direct contact, and shared surfaces
Boarding facilities, dog parks, and training classes are high-risk environments for transmission

Welfare Considerations

Kennel cough causes persistent coughing that disrupts sleep, eating, and normal activity. In severe cases it progresses to pneumonia. The welfare cost falls disproportionately on dogs in group housing who cannot avoid exposure. Vaccination, prompt isolation of symptomatic dogs, and good ventilation in boarding facilities are welfare obligations for facilities housing multiple dogs.

What You Can Do

Vaccinate dogs against Bordetella before boarding, training classes, or dog park visits
Isolate any dog showing coughing immediately from other dogs
Inform boarding facilities, daycares, and trainers if your dog develops cough after attendance
Request that boarding facilities require Bordetella vaccination for all attendees
Provide supportive care - humidification, rest, and soft food - for coughing dogs
See a vet if cough lasts more than 2 weeks or if the dog develops fever or lethargy
