Arizona Rabies Vaccination Law: Requirements, Penalties, and Quarantine

Arizona’s rabies vaccination law requires every dog three months or older to be vaccinated against rabies as a condition of getting a county dog license. Under ARS 11-1010, counties will not issue a license without a current vaccination certificate, which makes the shot effectively mandatory for any dog kept in Arizona for 30 consecutive days or more.¹ Skip it and you face misdemeanor exposure, late fees, and much harsher quarantine rules if your dog ever bites someone or tangles with a wild animal.

Which Animals the Law Covers

The state mandate applies to dogs. Every dog three months or older kept in Arizona for at least 30 consecutive days must be licensed, and licensing requires proof of vaccination.² Indoor-only status does not exempt a dog.

Arizona does not require rabies vaccination for cats at the state level, though some cities do. That said, ARS 11-1014’s bite quarantine rules apply to both dogs and cats, so an unvaccinated cat that bites someone faces the same mandatory pound quarantine as an unvaccinated dog.³ Vaccinating a cat is optional under state law but often the cheaper choice in practice.

When to Vaccinate and How Often

The first dose is due at three months of age. Arizona ties its schedule to the NASPHV Compendium of Animal Rabies Prevention and Control, which sets the minimum age and the booster interval based on the vaccine used.⁴

Initial dose at or after three months of age.
First booster one year after the initial dose, regardless of vaccine type.
After that, revaccination every three years if a three-year vaccine is used, or annually if a one-year vaccine is used.

A dog counts as currently vaccinated immediately after any booster. If your dog is overdue, get the booster done and the dog goes back onto the regular schedule for the vaccine type used.

Who Can Legally Give the Shot

Two categories of people can administer a rabies vaccine that counts under Arizona law: licensed veterinarians and certified rabies vaccinators. A certified rabies vaccinator is a non-veterinarian who has completed an approved training curriculum and works under a supervising veterinarian’s license, often at a shelter or a county vaccination clinic.⁴ County enforcement agents organize periodic vaccination clinics as well.¹

A store-bought vaccine given at home does not count. The vaccination has to be documented on an official certificate signed by the person who administered it.

Certificates and Tags

Every vaccination produces a certificate. ARS 11-1010 requires the certificate to show the owner’s name and address, a description of the dog, the vaccination date, the vaccine manufacturer and serial number, and the date the next revaccination is due, signed by the veterinarian or certified vaccinator who gave the shot.¹ A duplicate goes to the county enforcement agent within two weeks. Paper, electronic, and faxed certificates are all acceptable.

Once licensed, the dog gets a durable tag showing the county name, license number, and expiration year, and the tag must be worn on the collar or harness at all times.² Working livestock dogs, dogs at kennel club events, and racing dogs are excused from wearing the tag during those activities as long as they are properly vaccinated, licensed, and controlled.

How Licensing Locks In the Vaccine Rule

Each county’s board of supervisors sets its own license fee, and counties may offer lower rates for spayed or neutered dogs. Service animals and search and rescue dogs are exempt from license fees. The license period cannot exceed the revaccination interval set by the state veterinarian, so a three-year vaccine can support up to a three-year license.²

If you move to Arizona, an out-of-state vaccination certificate works for licensing here as long as it was signed by a veterinarian licensed in that state (or employed by a government agency there) and the vaccination meets Arizona’s standards.¹

Penalties for Skipping Vaccination or Licensing

Because you cannot license without vaccinating, the licensing penalties are how the state actually enforces the vaccine mandate. Knowingly failing to obtain a license after receiving written notification from the county enforcement agent is a class 2 misdemeanor under ARS 11-1008.²

Late licensing carries escalating fees. Applying less than one year after the deadline adds $2. Waiting a year or longer adds $10 per additional year, up to a $22 cap, on top of the regular license fee.

The bigger financial risk shows up later, when an unvaccinated dog bites someone or is exposed to rabies. That’s where owners feel the real cost.

Quarantine After a Bite or Rabies Exposure

Vaccination status changes the quarantine picture dramatically in both scenarios Arizona recognizes.

After a Bite

Any dog that bites a person must be quarantined for at least ten days. An unvaccinated dog must be confined at a county pound, or, if the owner requests and pays, at a veterinary hospital. A vaccinated dog can usually be quarantined at home with the county enforcement agent’s consent.³ Ten days of pound boarding versus ten days at home is the most immediate practical consequence of vaccination status.

Anyone with direct knowledge of a bite must report it to the county enforcement agent immediately. An impounded dog that bit someone generally cannot be released unless it has a current license, has been (or will be) spayed or neutered before release, or the owner pays a $50 recovery fee on top of other costs.

After Exposure to a Rabid Animal

If your dog encounters a confirmed or suspected rabid animal, the difference is even sharper. Arizona Department of Health Services protocols require an unvaccinated dog to be quarantined for 120 days in an approved facility run by a veterinarian or animal shelter.⁵ A vaccinated dog, even one overdue for a booster, needs only 45 days of observation and can be confined at the owner’s property under controlled conditions. In extreme cases, an unvaccinated animal exposed to rabies may be euthanized if transmission risk is too high.

Dog Bite Liability

Arizona imposes strict liability on dog owners under ARS 11-1025. If your dog bites someone who is in a public place or lawfully on private property, you are liable for damages whether or not the dog has ever shown aggression before.⁶

Vaccination status does not change the strict liability rule, but it shapes the damages. If the dog is unvaccinated, the victim may need post-exposure rabies treatment, which the CDC describes as immune globulin plus four vaccine doses over two weeks.⁷ That treatment is expensive and can add substantially to the damages an owner owes. A current certificate resolves the medical question quickly.

Medical Exemptions and Titer Tests

Arizona’s state statutes do not include an explicit medical exemption from rabies vaccination. Some municipalities allow one. Chino Valley, for example, lets an owner request a waiver of unaltered license fees when a licensed veterinarian recommends against vaccination on medical grounds.⁸ If your veterinarian believes vaccination poses a serious health risk, ask your county enforcement agent or local animal control office about the exemption process, and be ready with a written veterinary recommendation. Some jurisdictions require annual reevaluation.

Rabies antibody titer tests are not accepted as a legal substitute for vaccination in Arizona. Titers are used for international travel requirements only.

Traveling With Your Dog

Take a current rabies certificate whenever you leave the state. Most states require proof of rabies vaccination for dogs entering, and airlines have their own documentation rules. The USDA recommends checking both state and CDC requirements before you go.⁹ International trips to or from countries the CDC treats as high-risk require a Certification of U.S.-Issued Rabies Vaccination completed by a USDA-accredited veterinarian and endorsed by USDA before departure.
