Bordetella vaccine? in Health and Genetics Posted December 6, 2011 · Report reply I don't vax for bordetella unless I have no choice. My vet conspired with me to help me circumvent a 6 month interval a boarding kennel required because they felt it was unnecessary! Even after an outbreak at a dock diving event that we attended when the dogs were past the 1 year mark on their vaccine, only one of my dogs got it and she was especially susceptible as she went into heat 2 days after exposure. Her illness only involved coughing for less than a week and a snotty nose for about 9 days, no meds needed. When I taught group classes we suggested the bordetella vax, but did not require it and only had 1 case of it in the 3 years I was teaching, yet down the street at the humane society it was endemic (eg stressed dogs vs "normal" dogs).
