Primary Ciliary Dyskinesia in Dogs: Welfare Management

Primary ciliary dyskinesia is a rare inherited condition affecting respiratory tract function in dogs, causing chronic welfare impacts from recurrent respiratory infection.

Key Facts

PCD results from structural defects in cilia, impairing mucociliary clearance in the respiratory tract and sperm motility
Clinical signs include chronic rhinitis, sinusitis, bronchopneumonia and bronchiectasis from repeated respiratory infections
Old English Sheepdogs, Border Collies, English Springer Spaniels and Bichon Frises are predisposed breeds
Affected male dogs are often infertile from impaired sperm motility — the ciliary defect affects all ciliated cells

Welfare Considerations

PCD welfare is dominated by the chronic cycle of respiratory infection, antibiotic treatment and temporary improvement followed by relapse. Affected dogs require lifelong management including regular chest physiotherapy, prompt antibiotic treatment of exacerbations and monitoring for bronchiectasis development. Quality of life can be good in well-managed dogs with mild-to-moderate disease, but severe bronchiectasis progressively limits exercise tolerance and causes discomfort from productive coughing. Genetic testing in predisposed breeds can prevent transmission of this welfare-impacting condition.

What You Can Do

Implement daily chest physiotherapy (coupage) to support mucociliary clearance in affected dogs
Treat respiratory exacerbations promptly with appropriate antibiotics — culture-guided therapy reduces treatment failures
Monitor with regular thoracic radiographs to detect bronchiectasis development early
Screen breeding animals in predisposed breeds for PCD using available genetic tests
