If you dog had not finished the series, or was exposed to Bordatella prior to vaccination that could explain it.

NO vaccine is 100% effective, dog, cat OR human, however I believe they have to prove through testing that their vaccine is somewhere in the 90% range of effectiveness to market it.

Many bording kennels, obedience classes and groomers require the vaccination, and animals that are higher risk (ie. being around many other dogs) are reccomended they have this vaccine.
Exactly. Just because an animal is vaccinated doesn't mean that it is 100% not going to contract. Some are the same with humans. Just because you are vaccinated with the flu vaccination or pneumonia vac. doesn't mean that you can't get it. I had ONE dog with kennel cough and guess what? It didn't have the Bordatella intranasal......it was vaccinated with the injections.

Vet opinions do vary just as wide as human doctor's opinions.
