Dog Coughing in Fairfax, VA
When to monitor · When to call a vet · When to go in person
Coughing in dogs ranges from mild throat irritation to a sign of serious heart or lung disease. The character of the cough — dry, wet, honking, productive — combined with the timing (after exercise, at night, after drinking) helps identify the cause. Coughing in dogs is never normal but doesn't always mean emergency.
