Who needs a dog license in Arizona?
Under ARS § 11-1008 (accessed Aug 29, 2026), any dog three months of age or older that is kept in Arizona for 30 or more consecutive days must be licensed. The license is obtained from the county where the dog is kept. If you move to Arizona with a dog, you have 30 days from the date of continuous residence before the licensing requirement kicks in.
The license period for any individual dog may not exceed the dog's current rabies vaccination period — meaning if your dog's rabies booster is due in 12 months, the license can be issued for a maximum of 12 months regardless of county policy. A new license must be obtained upon renewal of the rabies vaccination.
Arizona's dog licensing law applies specifically to dogs. Unlike some states, Arizona's statewide statute does not mandate cat licensing — though individual cities may have local ordinances. Check with your city if you have cats.
The rabies vaccination requirement
ARS § 11-1010 (accessed Aug 29, 2026) establishes that no dog may be licensed in Arizona without proof of current rabies vaccination. The vaccination must be administered by a licensed veterinarian, a licensed veterinary technician under direct vet supervision, or a certified rabies vaccinator authorized under ARS § 32-2240.02. Dogs vaccinated in another state may be licensed in Arizona if the owner presents the vaccination certificate from a licensed veterinarian in that state and the vaccination meets Arizona's requirements.
At the time of licensing, the owner or veterinarian must present a rabies vaccination certificate. Under ARS § 11-1010, this certificate must include: the dog owner's name and address, a description of the dog (breed, color, age, sex), the vaccination date, the vaccine manufacturer and serial number, and the recommended revaccination date.
Fees and penalties
Arizona's county boards of supervisors set licensing fees. Under ARS § 11-1008(C), counties may — and most do — set lower fees for spayed or neutered dogs. Under ARS § 11-1008(F), service animals that have been trained and are actively used as service animals are exempt from licensing fees.
Late penalties under ARS § 11-1008 are tiered:
- If the license is less than one year overdue: $2 additional penalty
- If the license has been expired longer: $10 per year of delinquency, up to a maximum additional penalty of $22
Maricopa County (Phoenix metro) handles dog licensing through the Maricopa County Animal Care and Control (MCACC). Contact MCACC directly for current fee schedules, as fees are set by the county board and subject to change. Pima County (Tucson area) operates its own licensing program through Pima Animal Care Center.
How to apply: step by step
- Ensure rabies vaccination is current. Arizona requires current vaccination before licensing under ARS § 11-1010. If your dog's rabies is expired, visit your vet or a certified rabies vaccinator first.
- Find your county's animal services. Licensing is administered by your county. Maricopa County → MCACC. Pima County → Pima Animal Care Center. Other counties → contact the county sheriff or supervisor's office.
- Gather your documents. Rabies vaccination certificate, spay/neuter proof (for any discount), and your photo ID.
- Submit the application. Most Arizona counties offer online licensing portals. In-person applications are accepted at animal services offices and some participating vet clinics.
- Pay the fee. Most counties accept credit/debit cards online and check or cash in person.
- Receive your tag. Online applications typically result in a tag mailed within 1–2 weeks. In-person applicants get the tag the same day. The tag must be worn on the dog's collar at all times outside the owner's property.
County-level differences worth knowing
- Maricopa County (Phoenix area): Arizona's most populous county. Offers online licensing and renewal through the MCACC website. Lost tags can be replaced for a nominal fee. MCACC operates multiple shelter locations across the valley for in-person applications.
- Pima County (Tucson area): Pima Animal Care Center offers a reduced fee for senior residents. Online licensing available. Annual renewal reminder notices are sent to registered owners.
- Yavapai, Coconino, Navajo counties: Rural counties with lower population density. Licensing is administered by county sheriff or animal control offices. Confirm availability of online applications with your specific county.
