Kennel Cough: Welfare and Prevention in Socialised Dogs

Kennel cough is a highly contagious respiratory infection in dogs that causes significant discomfort and can progress to serious pneumonia in vulnerable animals.

Key Facts

Kennel cough is caused primarily by Bordetella bronchiseptica often combined with viral agents
The infection spreads rapidly in situations where dogs are in close contact including kennels and dog parks
The characteristic harsh hacking cough is caused by inflammation of the trachea and bronchi
Most healthy adult dogs recover without treatment within 1-2 weeks
Puppies, elderly dogs, and immunocompromised dogs face risk of progression to serious pneumonia

Welfare Considerations

Kennel cough causes genuine discomfort: the persistent, harsh coughing is physically demanding and distressing, occurring many times per hour in affected dogs. Severe cases cause retching, gagging, and nasal discharge that impair feeding and sleep. The distress of coughing paroxysms is apparent in affected dogs. Vulnerable animals including puppies and elderly dogs can develop secondary bacterial pneumonia that is a serious welfare emergency requiring intensive veterinary care. Intranasal or injectable Bordetella vaccination significantly reduces severity and duration of illness in vaccinated dogs, making vaccination a welfare intervention rather than merely an administrative requirement for boarding kennels. Appropriate antibiotic treatment in severe cases shortens illness duration.

What You Can Do

Ensure dogs are appropriately vaccinated against kennel cough before any social contact situations
Isolate coughing dogs immediately from other dogs to prevent spread
Seek veterinary advice for puppies, elderly dogs, or immunocompromised animals showing respiratory signs
Consider vaccination as a welfare measure even for dogs without boarding requirements
