Bordetella Vaccine for Dogs: Protecting Your Pooch From Kennel Cough

You may have heard of a respiratory illness dogs can catch called “kennel cough.” But did you know the term kennel cough describes more than one disease? It’s actually a blanket term encompassing many different infectious respiratory illnesses.

While many cases of kennel cough are mild, some cases do develop into pneumonia, making this incredibly contagious disease one to avoid. The good news is that we do have vaccines, like the Bordetella vaccine, to help protect your pup against this nasty honking cough.

What Is Kennel Cough?

Several viruses and bacteria can cause kennel cough, often at the same time. The group of organisms that causes kennel cough affects the upper respiratory tract of dogs and is characterized by inflammation of the trachea and bronchi.

Infectious tracheobronchitis is the scientific and more accurate term for kennel cough. The term tracheobronchitis describes the location of the infection in the windpipe, aka the trachea and bronchial tubes.

Signs of kennel cough are:

  • Persistent honking cough
  • Nasal discharge
  • Reduced appetite
  • Mild lethargy

Like a cold in humans, it is very contagious and found in places where dogs come in contact with one another. All it takes is one infected dog to sneeze, bark or cough, and the surrounding air and environment will be flooded with thousands of infectious kennel cough “bugs.”

Places like boarding facilities, shelters, doggy daycare and training facilities, and dog parks are high-risk zones for dogs to contract this upper respiratory infection. Because the infection spreads when dogs are housed together, it is often seen soon after dogs have been in kennels—hence the name “kennel cough.”

While kennel cough is not a fatal disease, tracheobronchitis is very uncomfortable for dogs­ (and their parents, who must endure the loud, persistent, honking cough that comes with it).

What Is the Bordetella Vaccine?

Bordetella bronchiseptica is a bacterium that is commonly associated with the respiratory disease in dogs that causes kennel cough, or infectious tracheobronchitis.

The Bordetella vaccine for dogs protects against this specific bacterium and is widely available to keep your dog safe from kennel cough.

Bordetella vaccination is given either by injection or intra-nasal route. Intra-nasal refers to the liquid vaccine administered as nose drops. This allows local immunity to develop on the mucous membranes of the nose, throat and windpipe where the infectious agents first attack. The injectable version goes beneath the skin in the subcutaneous tissue, not the muscle, making this one of the easiest vaccines for pups to receive. Intra-nasal vaccination is the choice of many veterinarians but there are exceptions where the injectable version is preferred.

Does My Dog Need the Bordetella Vaccine?

Vaccination is the best way to protect your dog from illnesses associated with canine infectious trache­obronchitis, particularly if your dog frequents kennels, groomers, dog parks, dog sporting events or training classes. While some veterinarians recommend the Bordetella vaccine only for dogs who spend time in those environments, many others recommend the vaccine for all dogs, regardless of their risk. That’s because Bordetella is so easily transmitted and because its vaccine is well tolerated in most dogs. Most dogs are safe candidates for the Bordetella vaccine, other than dogs who are immunocompromised.

Bordetella Vaccine Schedule

While the Bordetella vaccine for dogs is not legally required, it is one of the most frequently given vaccines. In fact, most boarding, veterinary and daycare facilities do require this vaccine to be up-to-date if you choose to bring your dog to one of these facilities.

The intranasal version of the vaccine is typically administered annually, although boarding facilities or hospitals may recommend it every six months.

For adult dogs or puppies older than 16 weeks, the intranasal vaccine can be given once, and the injectable vaccine should be given twice, two to four weeks apart. If puppies receive either the intranasal or injectable vaccine prior to 16 weeks, they typically get a booster the following month. Your veterinarian will work with you to determine if your dog is at risk and to create the best vaccine schedule for your dog if vaccination is advised.

Keep in mind that it takes roughly 10 to 14 days for partial immunity to develop after the vaccine has been administered. Some places will require this period of time to pass before approving your dog.

Bordetella Vaccine Side Effects

 It is mandatory for the patient's immune system to function properly in order to respond appropriately to a vaccine challenge. If the patient has a disease, the immune system will be so “occupied” fighting the disease that it will respond poorly to the vaccine.

Dogs with a history of a mild, acute post-vaccination reaction (e.g., facial swelling) are commonly treated with medications prior to vaccination.

Like with all vaccinations, the Bordetella vaccine may lead to temporary risks and side effects that all dog owners should be aware of. The first thing often noticed is a low-grade fever shortly after vaccines (after about 24 hours). This is completely normal and considered a common side effect of the vaccination. You may see your dog experience a change in behavior, such as lack of energy and loss of appetite.

While kennel cough often is a mild disease, the cough may be chronic, lasting for several weeks in some cases. The Bordetella vaccine is a very safe vaccine and widely recommended to protect pups at risk for this widely contagious illness.
