What Is Kennel Cough?

Kennel cough is a lung infection in dogs that irritates and swells the upper breathing passages around the dog’s throat and windpipe. It often leads to an ongoing hacking cough that can sound like honking or gagging. Most dogs get better on their own. The illness moves around quickly among dogs in places where dogs mix closely such as boarding facilities or dog parks.

Causes of Kennel Cough

Kennel cough is not caused by one germ. Instead it comes from a group of viruses and bacteria all together called dog cough sickness mix.

  1. Bordetella bacteria
  2. Parainfluenza virus
  3. Adenovirus type two
  4. Other germs and tiny bugs

In many cases a virus infection weakens throat defenses and lets bacteria grow more, making the cough worse. It spreads through droplets in the air when an infected dog coughs or sneezes and by touching dirty items such as water dishes or play toys.

Common Signs to Watch For

Daily life signs of kennel cough are easy to spot. Look for:

  • A loud dry cough that sounds strong or like honking
  • Sometimes gagging or dry heaving after coughing
  • Sneezing fits and draining fluid from the nose or eyes
  • Slight fever or eating less in some dogs

Most dogs stay happy and playful despite the cough. Puppies, older dogs or those with other health issues may show worse signs and need closer watch.

Home Remedies for Kennel Cough

Simple Steps to Help Your Dog Feel Better

  • Rest Time Keep your dog in a quiet space. Limit exercise until coughing eases to avoid throat irritation.
  • Moist Air Let your dog sit in a steamy bathroom while you shower. Moist air soothes an irritated throat.
  • Water and Soft Food Make sure fresh water is always nearby. Offer wet or warm food if your dog’s throat hurts.
  • Use a Harness, Not a Collar A harness stops pressure on the windpipe during walks, lowering cough causes.
  • Keep Your Dog Apart Keep your dog apart for two to three weeks after symptoms start to stop it from spreading.
  • Follow Your Vet’s Advice Give the medicines your vet prescribed, like antibiotics or anti-swelling medicine, exactly as directed.

These steps help most dogs recover within one to three weeks without stronger treatments.

Stopping Future Coughs

Vaccination is the best protection against the main kennel cough germs. Your vet may give:

  • Key vaccines for parainfluenza and adenovirus
  • Bordetella vaccine as nose drops or a shot
  • Dog flu vaccine if needed

Vaccines do not offer complete protection but they make symptoms milder and lower the chance of pneumonia. Dog boarding and daycare places often ask for vaccine proof for Bordetella.

When to Get Urgent Help

Though kennel cough is often mild, look for these warning signs

  • Trouble breathing or fast breathing
  • Cough that lasts more than three weeks
  • High fever over 103°F
  • Very tired and not eating

These signs may point to a serious lung infection or other big problems. Contact your vet right away if you see any of these.
