If you think your dog may have kennel cough and you are worried about it spreading the illness to other pets or people in your family, read on to learn more about it.

Kennel Cough – How Contagious Is It?

Kennel cough is extremely contagious. It is an airborne disease, so it spreads through the air. In a kennel or home where dogs are not vaccinated, it will likely infect every dog. 

What Kennel Cough Is

Kennel cough is a respiratory illness that affects dogs. It is caused by a bacterium called Bordetella bronchiseptica.

When dogs contract these bacteria they are often already infected with a common canine virus that has weakened the immune system and made them more susceptible to the bacteria. 

How Dogs Get Kennel Cough

Kennel cough is spread among unvaccinated dogs. If your dog is unvaccinated and is exposed to a dog who has kennel cough, your dog will likely contract it.

How Long Does Kennel Cough Last?

Kennel cough can last a few days or a few weeks. Dogs that have weak immune systems are more likely to suffer more severe and long-term symptoms.

Is Kennel Cough Dangerous?

Kennel cough is generally not dangerous to dogs who are otherwise healthy.

Most dogs do not require treatment for kennel cough, but puppies, elderly dogs, or dogs who have compromised immune systems or other health problems may need veterinary care. 

Kennel Cough Contagious Period

Kennel cough is contagious within the first 14 days but is the most contagious during the first seven days.

Can Humans Catch Kennel Cough?

Humans can catch kennel cough, but it is rare. Babies, the elderly, and anyone with a weakened immune system are the most at risk for catching it. 

Symptoms of Kennel Cough in Humans

Symptoms of kennel cough in humans are similar to that of the common cold. They can include:

  • Sore throat.
  • Persistent cough.
  • Fever.
  • Fatigue.
  • Difficulty swallowing.

Can Kennel Cough Be Spread by Humans?

Humans can spread kennel cough to other humans and to dogs. Since it is rare for humans to contract kennel cough, they are not the most common cause of kennel cough outbreaks.

Can Humans Carry Kennel Cough on Their Clothes?

Kennel cough is spread by fluid droplets that are coughed or sneezed.

While the bacteria that cause kennel cough cannot survive long outside the body, there is a possibility it could be spread on clothing.

Kennel Cough Vaccine Effectiveness

Kennel cough can be prevented with a vaccine. There are two types of kennel cough vaccine. One is administered through the nose, and the other is injected.

The intranasal vaccine begins working immediately, but the injectable vaccine takes up to five days to start working.

During these five days, a dog may still be able to become sick with kennel cough and spread it to others. Both versions of the vaccine are only about 60% effective.
