Yes, and they remind you a couple weeks before it expires when they have your dog on file. I have heard that Bordatello vaccine does not prevent all types of Kennel Cough--there are so many variants.Does your boarder require the Bordetella vaccine? Zulu's doggy day care requires that the vaccine is done every six months. It is a wise business decision, given that it is so contagious. He has been going there since he was a pup, and there has never been an outbreak. If they don't, and you are otherwise happy with them, it would not hurt to have him vaccinated, just to be on the safe side.
