Hi Jeanne! I will look up more info. for you, but I always just get the core vaccinations: Parvo, Distemper, Rabies. Parvo should last 7.5 yrs (lifetime immunity is likely, but they won't quite say it yet and still recommend titer), Distemper lasts 3 yrs. (longer actually, but the 3 years was a "compromise") - but you could titer. Rabies, after the 1st year booster, should be 3 years.
