Vaccination Requirements

To obtain a dog license, your dog must be currently inoculated with a rabies vaccination. The first vaccination is required at the age of four months and needs to be updated every one or three years, depending on the type of vaccination given. Keeping your dog current on their vaccinations prevents the contraction and the spread of various diseases.
