This is from one article. Hope this helps. It's time for me to take Kacee, too.
Rabies shots are started at sixteen weeks of age, boostered a year later, and every one to three years after that, depending on local laws and your veterinarian's recommendation. Unvaccinated dogs that come into close contact with a skunk must be quarantined or put to sleep. Vaccinated dogs that have skunk contact should be given a rabies booster as soon as possible, regardless of when they were last immunized.
