Since your dog was in a boarding facility, he probably just picked something up; it's probably a coincidence. There are so many viruses out there, you're right; the bordetella vaccine is similar to the human flu shot in that it only targets one strain. We're currently fighting a respiratory corona virus @ work; I'd never heard of it, but my dog had a case of corona virus years ago & it was a digestive tract thing. So I wonder if sometimes flu vaccines trigger a change in the flu, so that it can still survive; thereby creating a new strain that we have to chase after.
