What Pennsylvania law says

  • 3 P.S. 455.8 sets the requirement (MSU).
  • Dogs imported into Pennsylvania need a health certificate and rabies vaccination (459-214).

How rabies boosters work

The first rabies vaccine is treated as good for one year, no matter which product is used. After the one-year booster, vaccines labeled for three years are generally accepted as protecting for three years, if state and local law allow it (Compendium of Animal Rabies Prevention and Control). Your rabies certificate shows the exact due date, and that date is what animal control and licensing offices go by. More detail: how long a rabies shot is good for.

Cats and other pets

Cats are covered by Pennsylvania law on the same schedule as dogs.

Rabies vaccination is also tied to licensing in many places; see Pennsylvania dog license requirements. Your local veterinarian or a low-cost vaccine clinic can give the shot and issue the certificate and tag.
