"Unexplained Dog Illness Baffles Veterinarians and Shelters Across America"

Veterinarians in the Washington, D.C. area are puzzled by a respiratory illness affecting dogs in at least five states. The illness starts with a persistent cough and can progress to pneumonia and severe respiratory distress. While the exact cause is unknown, there is speculation that it could be a variant of canine influenza. Dog owners are advised to avoid dog parks and day care if possible and to seek veterinary care if their dog becomes lethargic, loses interest in eating, or develops a discharge from its nose. Vaccinations against Bordetella, canine influenza, and distemper are recommended as a precautionary measure.
