Arizona's Dog Laws, Quoted: Licences, Vaccination and Running at Large

The state sets the framework and the county sets the numbers. Here is the statute itself, section by section, including the out-of-state vaccination provision most new arrivals never find.

Arizona publishes its dog law in a form you can actually read, and it is shorter than you would expect.

Title 11, Chapter 7, Article 6 of the Arizona Revised Statutes covers licensing, vaccination, kennels and dogs at large. It sits at azleg.gov and returns a real 404 for a section that does not exist, which means every quotation on this page can be checked.

That matters more than it sounds. Arizona is one of three exceptions we have found.

One thing to understand before you read on: the state sets the framework and the county sets the numbers. Almost every operative provision below hands a decision to "the board of supervisors of each county". So Arizona law tells you that you need a licence; Maricopa County tells you it costs $22.

What the state requires

Requirement	Section
Rabies vaccination before a licence issues	11-1010(A)
Annual licence, fee set by the county	11-1008(A)
Licence tag worn on a collar or harness at all times	11-1008(B)
Licence tag worn by any dog over three months running at large	11-1012(C)
No vicious dog, and no female dog in season, at large	11-1012(A)
Leash or physical restraint in a public park or on public school property	11-1012(D)
Kennel permit at five or more dogs, unless each is licensed	11-1009(A)

The licence

ARS 11-1008(A), verbatim:

"The board of supervisors of each county may set a license fee that shall be paid for each dog three months of age or older that is kept, harbored or maintained within the boundaries of this state for at least thirty consecutive days of each calendar year."

Two conditions worth reading twice. Three months of age or older, and thirty consecutive days in Arizona. A dog visiting for a fortnight is not caught. A dog that has moved here is.

Timing, verbatim: "License fees shall become payable at the discretion of the board of supervisors of each county. The licensing period shall not exceed the period of time for revaccination as designated by the state veterinarian. License fees shall be paid within ninety days to the board of supervisors."

The licence period is tied to revaccination, which is why Maricopa County runs its licence year off the rabies certificate date rather than off a calendar.

Late penalties, on a rising scale, verbatim: "A penalty fee of two dollars shall be paid if the license application is made less than one year after the date on which the dog is required to be licensed under this article. If the license application is made one year or later from the date on which the dog is required to be licensed, an additional penalty fee of ten dollars shall be paid for each subsequent year up to a maximum of twenty-two dollars."

With an exemption for new arrivals, verbatim: "This penalty shall not be assessed against applicants who provide adequate proof that the dog to be licensed has been in their possession in this state less than thirty consecutive days."

Lower fees for altered dogs are permitted, not required, verbatim: "The board of supervisors may set license fees that are lower for dogs permanently incapable of procreation. An applicant for a license for a dog claimed to be incapable of procreation shall provide adequate proof satisfactory to the county enforcement agent that the dog has been surgically altered to be permanently incapable of procreation."

Where the money goes, verbatim: "All fees and penalties shall be deposited in the rabies control fund pursuant to section 11-1011."

The tag, and what it must say

ARS 11-1008(B), verbatim:

"If the board of supervisors adopts a license fee, the board shall provide durable dog tags. Each dog licensed under the terms of this article shall receive, at the time of licensing, such a tag on which shall be inscribed the name of the county, the number of the license and the year in which it expires. The tag shall be attached to a collar or harness that shall be worn by the dog at all times, except as otherwise provided in this article."

County name, licence number, expiry year. And worn at all times.

A lost tag is replaceable, verbatim: "Whenever a dog tag is lost, a replacement tag shall be issued on application by the owner and payment of a fee established by the board of supervisors."

Free licences for three categories

ARS 11-1008(F) removes the fee entirely, and it is more generous than most states.

Verbatim in substance, the board of supervisors "may not charge an individual who has a disability and who uses a service animal as defined in section 11-1024, a person that trains a service animal as defined in section 11-1024 or an individual who uses a search and rescue dog a license fee for that dog."

Three categories: a service animal user, a service animal trainer, and a search and rescue dog handler.

A search and rescue applicant must "provide adequate proof satisfactory to the county enforcement agent that the dog is a search and rescue dog."

A service animal applicant signs a statement, and the statute prints both the wording and the penalty. Verbatim: "A person who makes a false statement pursuant to this paragraph is guilty of a petty offense and is subject to a fine that does not exceed fifty dollars."

The statutory form is short enough to quote, verbatim: "By signing this document, I declare that the dog to be licensed is a service animal as defined in section 11-1024, Arizona Revised Statutes, and I understand that a person who makes a false statement pursuant to section 11-1008, Arizona Revised Statutes, is guilty of a petty offense and is subject to a fine that does not exceed fifty dollars."

Vaccination

ARS 11-1010(A), verbatim:

"Before a license is issued for any dog, the owner or a veterinarian must present a paper or electronic copy or telefacsimile of the vaccination certificate signed by a veterinarian stating the owner's name and address, and giving the dog's description, date of vaccination, manufacturer and serial number of the vaccine used and date revaccination is due."

Six items on that certificate, and it is worth checking yours has all of them before you apply: owner name and address, the dog's description, the date, the manufacturer, the serial number, and the revaccination due date.

The bar, verbatim: "A dog shall not be licensed unless it is vaccinated in accordance with this article and the rules adopted pursuant to this article."

A duplicate goes to the county, verbatim: "A duplicate of each rabies vaccination certificate issued shall be transmitted to the county enforcement agent within two weeks after the date the dog was vaccinated."

An out-of-state vaccination is expressly accepted, and this is the provision most useful to somebody who has just moved. ARS 11-1010(B), verbatim: "A dog vaccinated in any other state prior to entry into Arizona may be licensed in Arizona provided that, at the time of licensing, the owner of the dog presents a vaccination certificate, signed by a veterinarian licensed to practice in that state or a veterinarian employed by a governmental agency in that state, stating the owner's name and address, and giving the dog's description, date of vaccination and type, manufacturer and serial number of the vaccine used."

You do not need to revaccinate to licence, provided the paperwork carries what the statute asks for. Our pet vaccination schedules guide covers what a rabies schedule looks like, and our pet health and vaccination tracker is a place to keep the certificate details together.

Clinics, verbatim: "The county enforcement agent shall provide for vaccination clinics as deemed necessary. The vaccination shall be performed by a veterinarian or by a rabies vaccinator who is certified in the administration of rabies vaccines pursuant to section 32-2240.02."

Dogs at large, and where the leash rule actually bites

ARS 11-1012 is four short subsections, and its scope is narrower than most people assume.

(A), verbatim: "Neither a female dog during her breeding or mating season nor a vicious dog shall be permitted at large."

So the state's absolute at-large prohibition applies to two categories, not to all dogs.

(B), verbatim: "In a rabies quarantine area, no dogs shall be permitted at large. Each dog shall be confined within an enclosure on the owner's property, secured so that the dog is confined entirely to the owner's property, or on a leash not to exceed six feet in length and directly under the owner's control when not on the owner's property."

The six-foot figure is a rabies-quarantine provision at state level. It is not a statewide everyday rule. That everyday rule comes from the county and the city, both of which also use six feet.

(C), verbatim: "Any dog over the age of three months running at large shall wear a collar or harness to which is attached a valid license tag."

(D), verbatim: "No person in charge of any dog shall permit such dog in a public park or upon any public school property unless the dog is physically restrained by a leash, enclosed in a car, cage or similar enclosure or being exhibited or trained at a recognized kennel club event, public school or park sponsored event."

Public parks and public school property. That is the state's leash requirement, and it is the same narrow shape as Washington DC's. The reason a dog must be on a lead on a Phoenix street is not this section; it is Phoenix City Code 8-14(A), which we cover separately alongside the county ordinance.

The exemption list in (C), verbatim: "Dogs that are used for control of livestock, being used or trained for hunting or dogs, being exhibited or trained at a kennel club event or engaged in races approved by the Arizona racing commission, and while the dogs are being transported to and from such events, need not wear a collar or harness with a valid license attached provided that they are properly vaccinated, licensed and controlled."

Note the proviso at the end. The exemption is from wearing the tag, not from being licensed and vaccinated.

Kennels, and the escape hatch

ARS 11-1009(A), verbatim: "A person operating a kennel shall obtain a permit issued by the board of supervisors of the county where the kennel is located except if each individual dog is licensed."

That exception is the practical answer for a large household. Maricopa County's Ordinance P-13 defines a kennel as an area where a person keeps "five or more dogs under controlled conditions", so five dogs puts you in kennel territory. Licensing each of them takes you out of it.

The numbers, verbatim: "The annual fee for the kennel permit is seventy-five dollars or the actual cost of recovery as determined by the board of supervisors." And: "A person who fails to obtain a kennel permit under this section is subject to a penalty of twenty-five dollars in addition to the annual fee."

Individual licensing inside a kennel, verbatim: "A dog remaining within the kennel is not required to be licensed individually under section 11-1008. A dog leaving the controlled kennel conditions shall be licensed under section 11-1008 except if the dog is only being transported to another kennel that has a permit issued under this section."

Inspection thresholds turn on twenty dogs, verbatim: a kennel housing "fewer than twenty dogs may be subject to an inspection by the county enforcement agent during regular business hours if the county enforcement agent has received a citizen or law enforcement complaint in writing", while one housing "twenty dogs or more shall allow inspections of the kennel by the county enforcement agent as a condition of receiving a kennel permit." Hunting-dog kennels are excepted from that subsection.

And a permit can be refused for an animal welfare conviction, verbatim: "The county shall deny a kennel permit to any person who has been convicted of a violation of section 13-2910 or 13-2910.01 or any other state, county or municipal animal welfare law, except violations of license and leash laws."

Note the carve-out at the end. Licence and leash violations do not disqualify you; cruelty convictions do.

The criminal provisions

Two, both class 2 misdemeanours, and both triggered by written notice rather than by the underlying failure.

ARS 11-1008(E), verbatim: "Any person who knowingly fails within fifteen days after written notification from the county enforcement agent to obtain a license for a dog required to be licensed, counterfeits an official dog tag, removes such tag from any dog for the purpose of intentional and malicious mischief or places a dog tag on a dog unless the tag was issued for that particular dog is guilty of a class 2 misdemeanor."

ARS 11-1009(G), verbatim: "A person who knowingly fails to obtain a kennel permit within thirty days after written notification from the county enforcement agent is guilty of a class 2 misdemeanor."

Fifteen days for a licence, thirty for a kennel permit, both from written notification. So the criminal exposure begins when you have been told, not when the deadline passed.

Bite liability, which is the strictest thing in the article

Three sections sit alongside the licensing provisions and they are the ones with money attached.

ARS 11-1025(A), verbatim: "The owner of a dog that bites a person when the person is in or on a public place or lawfully in or on a private place, including the property of the owner of the dog, is liable for damages suffered by the person bitten, regardless of the former viciousness of the dog or the owner's knowledge of its viciousness."

"Regardless of the former viciousness of the dog or the owner's knowledge of its viciousness." So the argument that the dog has never done it before does not go to liability. And read the scope: it covers a bite on your own property where the bitten person is lawfully there.

A duty to identify yourself. Subsection (B), verbatim: "A person who owns or is responsible for the care of a dog that bites a person when the person is in or on a public place or lawfully in or on a private place, including the property of the owner of the dog, shall provide the owner's contact information to the person who suffered the dog bite."

And a breed provision stronger than most states have. Subsection (C), verbatim: "The breed of a dog may not be considered in findings of facts or conclusions of law entered by a court, administrative law judge, hearing officer, arbitrator or other legal decision-maker regarding whether a dog is aggressive or vicious or has created liability."

That binds legal decision-makers. It does not bind landlords or insurers, who set breed policies by contract. Our renting with a large or restricted-breed dog guide covers that side.

The statute also defines its terms. Verbatim: "'Vicious' means that a dog has a propensity to attack, to cause injury to or to otherwise endanger the safety of human beings without provocation or has been found to have any of these traits after a hearing before a court of competent jurisdiction or before a hearing officer pursuant to section 11-1006." And: "'Aggressive' means that a dog has bitten a person or domestic animal without provocation or has a known history of attacking persons or domestic animals without provocation."

Police and military dogs are carved out in subsection (D) in specified circumstances, subject to the agency having adopted a written policy on the necessary and appropriate use of a dog for that work.

The one defence the statute names

ARS 11-1027, verbatim in full: "Proof of provocation of the attack by the person injured shall be a defense to the action for damages. The issue of provocation shall be determined by whether a reasonable person would expect that the conduct or circumstances would be likely to provoke a dog."

A reasonable person standard, applied to the injured person's conduct.

And a wider rule for dogs at large

ARS 11-1020, verbatim in full: "Injury to any person or damage to any property by a dog while at large shall be the full responsibility of the dog owner or person or persons responsible for the dog when such damages were inflicted."

"Any property", and "full responsibility". That reaches past bites to a loose dog that causes a collision or wrecks a neighbour's garden, and it is the clearest financial reason in Arizona law to keep the lead on. Our dog bite quarantine in Maricopa County guide covers what happens to the dog itself after a bite, which is a county matter.

What the state leaves to somebody else

Worth naming, because it is most of what a dog owner actually meets.

The fee. Set by each county's board of supervisors. In Maricopa County that is $22 for a spayed or neutered dog and $55 for an intact one.

Everyday leash rules. The state covers public parks and school property. Maricopa County's Ordinance P-13 covers the unincorporated areas, and Phoenix City Code 8-14 covers the city, both with a six-foot limit.

Stray holds and pound fees. Maricopa County's ordinance sets a seventy-two hour minimum, and the county says it holds a licensed dog for a minimum of one hundred and twenty.

Bite quarantine. Also county. And the county's provision turns on whether the dog is licensed and vaccinated, which is the most concrete reason in Arizona to keep both current.

Heat. Not in the statute at all. Phoenix bars dogs from all city hiking trails at 100 degrees or warmer, and Maricopa County publishes the asphalt conversion table. Our summer heat safety for pets guide covers the general picture.

If you have just moved to Arizona

Find the rabies certificate and check it against the six items in 11-1010(A). If it has them, you do not need to revaccinate to licence.

You have thirty consecutive days before the licence requirement attaches, and 11-1008(A)'s late penalty expressly does not apply to a dog in your possession in the state for less than that.

Licence with your county, not the state. The state sets the framework; the county issues the tag.

Then buy a six-foot fixed lead, because all three layers of Arizona law use that figure.

Our guide to moving to a new city with a pet covers the rest, and our Phoenix hotel directory is a starting point if there is a gap before you move in.

Frequently asked questions

Does Arizona require a dog licence? Arizona Revised Statutes 11-1008 provides that each county's board of supervisors may set a licence fee payable for each dog three months of age or older kept in the state for at least thirty consecutive days of a calendar year. The requirement is implemented and priced at county level.

At what age must a dog be licensed in Arizona? Three months of age or older, per ARS 11-1008(A).

Do I need to licence my dog if I am visiting Arizona? The statute attaches to a dog kept, harboured or maintained in the state for at least thirty consecutive days of each calendar year, and 11-1008(A) exempts applicants who prove the dog has been in their possession in the state for less than thirty consecutive days from the late penalty.

Does Arizona accept an out-of-state rabies vaccination? Yes. ARS 11-1010(B) allows a dog vaccinated in another state to be licensed in Arizona on presentation of a certificate signed by a veterinarian licensed in that state, or employed there by a governmental agency, with the details the statute lists.

Is a dog licence free for a service animal in Arizona? Yes. ARS 11-1008(F) bars a county from charging a licence fee to an individual with a disability who uses a service animal, a person who trains one, or an individual who uses a search and rescue dog.

Where does Arizona require a dog to be on a leash? ARS 11-1012(D) covers public parks and public school property. The six-foot figure in 11-1012(B) applies in a rabies quarantine area. Everyday street leash rules come from county and city law.
