Multiple viruses and bacteria (in some cases, simultaneously), such as mycoplasma and the canine adenovirus, can cause this highly contagious disease – the presence of another dog is enough to transmit the infection. Kennel cough is an airborne upper respiratory infection that attacks the bronchioles and the trachea. It needs to be given at an appropriate time to be effective.Įverything You Need to Know about Kennel Cough.It doesn’t negate the need for a good infection control program.Vaccination very soon before boarding, particularly for a dog that has never been vaccinated against kennel cough before, is unlikely to result in protection from infection by the time of boarding. The intranasal kennel cough vaccine (squirted up the nose) takes a few (3-5) days to be effective, and the injectable vaccine takes even longer (a week or more). What often happens is people decide to board their animal at the last minute or realize the night before that they need their dog vaccinated, so the vaccine gets given a day (or less) before kenneling. The problem with this is vaccines are not immediately effective. One of the weak points of many kennel protocols is the requirement that the dog be vaccinated "before entry," or within a certain number of weeks or months. Some vaccines are better than others, and some animals respond better to vaccines than others.ģ) Timing is another issue. Vaccines help reduce the risk of illness, but they don’t completely eliminate it. Kennel cough vaccines are typically targeted against Bordetella bronchiseptica +/- canine parainfluenza, two important causes of kennel cough, but not the only causes.Ģ) No vaccine is 100% effective. It can be caused by many different viruses and bacteria, often in combination. Why isn’t the vaccine 100% effective?ġ) Kennel cough is a syndrome, not a specific disease. Relying solely on vaccination to prevent kennel cough is a weak approach that can ultimately fail, particularly if other infection control practices are poor or if vaccination protocols are illogical. Overall, it’s a sound policy, but it’s far from 100% effective and it needs to be part of an overall kennel infection control program to work.
