What to do now

Coughing can be airway irritation, infection, or heart/lung disease; breathing effort changes urgency.

Monitor

  • Track cough timing, frequency, sound, and triggers.
  • Watch breathing effort at rest, gum color, energy, and appetite.
  • Note exposure to other dogs, exercise, smoke, or collar pressure.

Call a vet

  • Call if coughing persists, worsens, or affects sleep or activity.
  • Call sooner if appetite, energy, or breathing changes.
  • Ask if contagious respiratory disease precautions are needed.

Emergency now

  • Use emergency care for trouble breathing, blue or pale gums, collapse, or severe weakness.
  • Use emergency care for coughing with repeated fainting.
  • Keep your dog calm while traveling.
