Kennel cough is a highly contagious respiratory disease in dogs. It is most often benign, but can become serious in puppies, elderly or fragile dogs.

What exactly is it?

It is not a single disease, but an infectious complex due to several agents:

• Bordetella bronchiseptica (bacteria, very common)

• parainfluenza virus

• canine adenovirus

• sometimes influenza viruses

The infection irritates the trachea and bronchi → characteristic dry cough.

How is it contracted?

Through:

• air (coughing, sneezing)

• close contact

• collective places: boarding kennels, shelters, parks, breeding facilities, groomers

Rapid incubation: 2 to 10 days
A dog can be contagious before symptoms appear.

Typical symptoms

• sudden, harsh, dry cough, like a "honk"

• sometimes paroxysmal after excitement or leash walking

• retching / small foamy discharges

• slight nasal discharge

• general condition often preserved

Signs of severity (urgent consultation):

• fever

• lethargy

• persistent wet cough

• respiratory difficulties

• puppy or elderly dog

Diagnosis

Most often clinical (symptoms + context).
Additional examinations if:

• severe symptoms

• no improvement

• suspected pneumonia

Prevention

• avoid contact if coughing is present

• isolate the sick dog

• disinfect shared items

Key takeaways

✔ Highly contagious
✔ Generally benign
✔ Can become serious in fragile dogs
