Pet licenses may be purchased through either the city or county, depending on where you live. You'll need to provide proof of current rabies vaccination. Also, fees are usually reduced for spayed and neutered pets. By getting your pet licensed (and microchipped!), you'll be increasing the chance of being reunited with your pet, should he or she ever get lost. Please note that some zip codes are served by multiple agencies. If you're not sure which agency serves your area, contact them directly.
