My dog is coughing — what now?

A cough is not a diagnosis. What matters is how much effort breathing takes, how hard the coughing fits are, and what else is happening at the same time.

First, how urgent is this?

Go now

  • Obvious effort to breathe, or open-mouth breathing.
  • Visible effort to breathe at rest, with a strong belly movement.
  • A blue tongue or blue gums.
  • Coughing until the dog collapses or briefly loses consciousness.
  • Coughing up fresh blood.

Contact your vet today

  • Coughing for several days without improving, or waking at night to cough.
  • A small breed aged 4 or over with a honking cough, triggered by pressing the neck.
  • Coughing with falling energy and appetite, or weight loss.
  • Other dogs in the household or the same walking group coughing too.

Record and observe

  • The odd cough, with normal energy, appetite and activity.
  • Coughing only when excited, pulling on the lead, or when the weather changes, and normal otherwise.
  • A heart patient already under vet care: count the coughing fits, and go back if they increase.

Before you set off

  • How often, when (night, after exercise, when excited) and what it sounds like (film it).
  • Whether white foam or food comes up at the end of a fit.
  • Any recent contact with other dogs, a boarding stay or a dog park.
  • A list of medicines and the time of the last dose.
  • Do not give human cough or cold medicine; do not stop a prescribed medicine on your own.

What your vet may ask and do

  • Ask: when the cough started, and what brings it on.
  • Ask: any breathing effort, fainting or reduced exercise tolerance.
  • Ask: contact with other dogs, and vaccination and worming history.
  • Do: listen to heart and lungs, and palpate the windpipe.
  • Do: X-rays for the windpipe, lungs and heart size.
  • Do: heart ultrasound, for a cough caused by heart disease.
  • Do: tracheoscopy or CT where needed.
