Short answer

Wisconsin requires dogs to be vaccinated against rabies no later than 5 months of age, with a booster within 1 year of the first shot (Wis. Stat. 95.21), by a veterinarian or a vet technician with a vet present. A vet can grant a one-year exemption. Proof of vaccination is needed for the dog license.

Wisconsin requires rabies vaccination by state law. Here is who must be vaccinated, when, and how the rules are enforced.

What Wisconsin law says

  • Wis. Stat. 95.21 sets the rabies control program (MSU).
  • Returning an impounded animal requires required vaccinations (173.23).

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

Wisconsin's state law covers dogs. Cats are not required by state law to be vaccinated, but local ordinances may require it.

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