Dog Coughing
Causes, warning signs, and when to reach out about a coughing dog in Lakeville, MN.
A coughing dog is hard to ignore – especially at night. Sometimes it's a mild kennel cough after boarding. Other times it points to airway irritation, heart disease, or something stuck that needs prompt care.
The sound can be dry and honking, wet and productive, or mixed with gagging that looks like your dog is trying to clear their throat. Those details help, but they don't replace an exam when the cough is persistent or your dog seems sick.
This guide covers common reasons dogs cough, what to watch for, and when to contact a veterinarian in Lakeville, MN.

What Causes Coughing In Dogs?

Coughing is a symptom, not a diagnosis. Common causes include:
- Kennel cough / infectious tracheobronchitis
- Canine influenza or other respiratory infections
- Tracheal irritation or collapsing trachea (especially small breeds)
- Allergies or inhaled irritants (smoke, dust)
- Heart disease with congestive changes
- Pneumonia
- Parasites (including heartworm disease in unprotected dogs)
- Foreign material in the throat or airway
- Reverse sneezing (often confused with coughing)
Age, breed, recent boarding/daycare, and whether the cough is worse with excitement or at night all help narrow the list.
Don’t Just Take Our Word For It

When Is Dog Coughing An Emergency?
Difficulty breathing is always an emergency – don't wait for a routine slot.
- Is struggling to breathe, breathing with effort, or has blue/gray gums
- Collapses or can't catch their breath after coughing
- Is coughing up blood
- Has a known heart condition and a sudden cough flare
- Choked on food/toys and is still in distress
- Has a fever and is rapidly declining
What To Do When Your Dog Is Coughing But Acting Normal
Many dogs with early kennel cough still eat and wag. That doesn't mean you should ignore it – especially if they were recently boarded, at daycare, or around other dogs.
- Note when the cough started and what it sounds like
- Limit exercise and excitement until you're advised otherwise
- Avoid dog parks / boarding until cleared
- Call us if the cough lasts more than a couple of days, worsens, or your dog stops eating
Do not give human cough syrups unless a veterinarian specifically directs it.


Kennel Cough Vs. Heart-Related Cough
Kennel cough often sounds harsh or honking and may follow social exposure. Heart-related cough is more common in older dogs, may worsen at night, and can come with reduced stamina or faster breathing at rest.
You can't reliably tell these apart from a phone description alone. An exam – and sometimes X-rays or other diagnostics – is how we sort infectious cough from cardiac or chronic airway disease.

F.A.Q
Should I walk my coughing dog?
Usually reduce exercise until the cough improves. Excitement and pulling on a collar can trigger coughing fits.
Is kennel cough contagious?
Yes. Keep your dog away from other dogs until your veterinarian says it's safe.
Does the Bordetella vaccine prevent all coughing?
It reduces risk and severity for some infectious causes, but no vaccine covers every respiratory illness.
Why does my dog cough more at night?
Nighttime cough can happen with airway irritation or heart disease. Persistent night cough deserves an exam.
Can heartworm cause coughing?
Yes. If prevention has lapsed, testing is important – especially with a new cough.
