Dog coughing
Many dog coughs are mild — a kennel-cough type that sounds harsh and honking in a bright dog, for example — but some coughs are serious. Treat coughing as urgent if your dog is also struggling to breathe, has blue, grey or pale gums, is coughing up blood or pink froth, is weak or collapsing, or has a swollen belly with rapid breathing. A sudden cough after possible choking, or a soft cough with tiredness and fast breathing in an older dog (which can suggest a heart problem), also needs prompt veterinary care. When in doubt, call your vet and describe the cough and your dog's breathing.
Go to a vet now if
- Coughing with difficulty breathing, or blue, grey, or pale gums
- Coughing up blood or pink, frothy fluid
- Weakness, collapse, or a sudden cough after possible choking
- Fast breathing at rest with tiredness, especially in an older dog
Call a vet today if
- A harsh, honking cough in a bright, active dog that is eating and breathing normally
- An occasional cough after exercise or excitement that quickly settles
What to tell the vet
- What the cough sounds like and how often
- Whether breathing is affected at rest
- Any blood or frothy fluid
- Energy level and appetite
- Recent kennels, dog parks, or choking
- Age, breed, weight, and heart history
What not to do
- Do not give human cough or cold medicines — many are unsafe for dogs
- Do not ignore a cough with laboured breathing or blue gums
- Do not exercise a dog that is coughing and short of breath
What your vet may check
Your vet will listen to the chest and may use imaging and other tests to tell a mild airway infection from a heart or lung problem, then treat the cause. Breathing distress is stabilised first.
Recovery support after veterinary assessment
Follow your vet's treatment and rest plan for the underlying cause. Any supportive care during recovery is used on veterinary advice.
Frequently asked questions
When is a dog's cough an emergency?
When it comes with difficulty breathing, blue or pale gums, coughing up blood or pink froth, weakness, collapse, or fast breathing at rest. These need urgent veterinary care.
Is kennel cough an emergency?
Usually not on its own — it is often a harsh, honking cough in an otherwise bright dog — but it should be checked by a vet, and any breathing difficulty makes it urgent.
Can I give my dog human cough medicine?
No, not without veterinary advice. Many human cough and cold products are unsafe for dogs. Your vet can recommend appropriate treatment for the cause.
