Short answer: Pattern matters. A dry, honking cough is usually kennel cough or tracheal collapse. A wet, productive cough suggests pneumonia or congestive heart failure. A cough that comes on with exercise or excitement points to heart disease. Coughing more than 7 days or any labored breathing = vet visit.
🚨 Red flag — call your vet now if: coughing up blood, blue or gray gums, labored breathing, collapse, or resting respiratory rate >40 breaths/min – go to a vet immediately.
What you should actually do
- Kennel cough (CIRDC): dry honking cough, often after boarding/grooming, usually self-limiting in 7-14 days.
- Tracheal collapse: small-breed (Yorkie, Pomeranian, Maltese) honking cough especially on excitement or pulling on collar.
- Congestive heart failure: soft wet cough, often at night or after lying down, +/- exercise intolerance and increased resting respiratory rate >30/min.
- Pneumonia: wet cough + fever + decreased appetite + rapid breathing – this is an emergency.
- Heartworm disease: chronic cough +/- exercise intolerance in any dog not on heartworm prevention.
The single most useful number you can measure at home is the sleeping respiratory rate. Normal dogs breathe 15-30 times per minute while asleep. A consistently elevated rate (>30) is the earliest sign of congestive heart failure – often weeks before the dog looks sick – and is a vet visit.
Kennel cough is more accurately called Canine Infectious Respiratory Disease Complex (CIRDC) – it’s a mix of viruses (parainfluenza, adenovirus-2, canine influenza) and bacteria (Bordetella, Mycoplasma). Most cases self-resolve, but a dog who is lethargic, off food, or who has had a wet productive cough for >10 days may have progressed to pneumonia and needs chest X-rays and antibiotics.
