How long does kennel cough last?

Kennel cough is a well-known canine health issue that is highly contagious and can rapidly spread among dog populations. Understanding the causes, symptoms, and treatment options for kennel cough can help dog owners effectively manage and prevent this condition. In this guide, we’ll cover everything you need to know about kennel cough in dogs, including the symptoms to look out for, causes, treatment options, and more.

What Is Kennel Cough?

Kennel cough, scientifically known as infectious tracheobronchitis, is a respiratory disease in dogs. It’s caused by a combination of bacteria (most commonly Bordetella bronchiseptica) and viruses (such as canine parainfluenza or adenovirus), which inflame the dog’s upper respiratory tract. Kennel cough is highly contagious and can spread easily through direct contact between dogs, through contaminated surfaces, or through the air.

Kennel Cough Symptoms

The most common symptom of kennel cough is a persistent, forceful cough that’s often described as sounding like a goose honking. The dog may also display symptoms like sneezing, runny nose, eye discharge, and in severe cases, lethargy, loss of appetite, and fever. Most dogs with kennel cough remain active and continue eating normally despite their cough.

Kennel Cough Causes

Kennel cough is caused by a variety of bacteria and viruses, including the bacteria Bordetella bronchiseptica and viruses like canine parainfluenza and canine adenovirus type 2. It's usually contracted in environments where dogs are in close proximity to one another, such as kennels, dog parks, or shelters.

Kennel Cough Treatment

In many cases, kennel cough will resolve on its own within 1-3 weeks with rest and fluids. However, in some cases, vets may prescribe antibiotics (to fight the bacterial component of the illness) and/or cough suppressants to help manage symptoms. It’s important to consult with your vet if your dog’s symptoms are severe or if the cough persists for more than a couple of weeks.

Kennel Cough in Dogs: How Long Does It Last?

The duration of kennel cough can vary. In most healthy dogs, the illness typically resolves within 1-3 weeks. However, puppies, elderly dogs, or immunocompromised dogs may develop a more severe form of the disease that could take longer to resolve and may lead to more serious complications like pneumonia. Seeking veterinary advice is important if your dog seems particularly unwell or is not improving after a couple of weeks.

Kennel Cough in Puppies

Kennel cough can be particularly serious in puppies due to their underdeveloped immune systems. Puppies with kennel cough may show more severe symptoms and are more at risk of developing complications like pneumonia. It’s crucial to seek veterinary attention promptly if you think your puppy has kennel cough.

Kennel Cough Vaccines

Vaccines are available for some of the viruses and bacteria that cause kennel cough, including the parainfluenza virus and Bordetella bronchiseptica. While not 100% effective (due to the multiple potential causes of kennel cough), vaccines can reduce the risk and severity of the illness. The Bordetella vaccine is often given intranasally or orally and requires annual boosters. It’s particularly recommended for dogs that are frequently in contact with other dogs.
