Provide plenty of fresh water
Use a humidifier or steam from a bathroom
Keep your dog away from smoke, dust, and strong odors
Feed small, easy-to-eat meals if coughing affects eating
Use a harness instead of a collar for walks
Monitor for worsening symptoms
Contact a veterinarian if symptoms are severe, persistent, or your dog is very young, old, or has other health problems
Do not give human cough medicines unless a veterinarian says it is safe
Follow any prescribed veterinary treatment exactly as directed
