Vaccinating your dog with the Bordetella vaccine will help reduce the risk. However, your dog can still contract kennel cough even if he or she has been vaccinated. There are many strains and mutations of the virus. The Bordetella vaccine is similar to the “flu shot” for people; each year, a vaccine is developed based on which strains are suspected to be most prevalent. Simply put, when your dog has a Bordetella vaccination, it doesn’t guarantee he or she will not get kennel cough. A strong immune system is the best defense against infection. This is why puppies, elderly dogs, and dogs with weakened immune systems are more susceptible to contracting kennel cough.
