the vaccine doesnt ensure that your dog is immune...... there is a chance they could still get it, whether they got the vaccine or not........  
My toby had the vaccine as well,...... but then he got kennel cough..... the vaccine typically only guards against a few of the viruses involved (usually only bordatella (sp?).... but there are SEVERAL different viruses when brought together cause kennel cough...... so in short, just because you guard against one of the "culprits" doesnt mean they cant get it     |
