My dog has had the kennel cough (Bordatella) vaccine and still came down with kennel cough at another facility. Do they really need it?

Yes. The vaccine is about 85% effective and is similar to the human flu vaccine in the fact that it protects us, but not from all the strains of the virus. Just like humans, sometimes a dog’s immune system is not as strong as it is at other times, making it easier for them to come down with kennel cough. In most cases, the kennel cough will be less severe due to the vaccination.
