Where Dogs Are Not Allowed in Phoenix

A temperature, a fence line, a piece of signage. Every Phoenix restriction on dogs, the rule that creates it, and the gaps we refuse to guess about.

Most Phoenix restrictions on dogs are not permanent bans. They are conditions: a temperature, a fence line, a piece of signage, a park board decision. Which makes them easy to get wrong, because the same place is open on Tuesday and closed on Thursday.

Here is the list, with the rule that creates each one and the source that publishes it.

The restrictions at a glance

Seven restrictions cover almost every "can my dog go there" question in Phoenix. Each one has a condition that switches it on and a layer of government behind it.

Restriction	What switches it on	Who sets it
All city hiking trails closed to dogs	100 degrees or warmer	City of Phoenix
Named trails closed to everyone, 8 a.m. to 5 p.m.	An Extreme Heat Warning	City of Phoenix
A park, preserve, or any part of one closed to dogs	A Parks Director or Parks Board decision	City of Phoenix
Leash only, six feet maximum	Being outside a designated dog park	Phoenix City Code 8-14(A)
Leash required in parks and on school grounds	Being on public park or school land	Arizona, ARS 11-1012(D)
No outdoor restraint	Heat above 100, heat advisory, monsoon, or dust storm warning	Phoenix tethering ordinance
Dog park entry barred	Under four months, unlicensed, unvaccinated, or in heat	Posted city dog park rules

City hiking trails, at 100 degrees or warmer

The clearest and most consequential one. Verbatim from the City of Phoenix heat safety page:

"Did you know that dogs are prohibited on ALL city hiking trails when the temperature is 100 degrees or warmer?"

The capitals are the city's. All city trails, on any day it reaches 100. No date range, no exceptions listed, and no distinction by trail difficulty.

Phoenix's trail network is large, so this covers a lot of ground: the Phoenix Mountains Preserve, South Mountain Park and Preserve, Camelback, Piestewa Peak.

We cover the detail, including the county's asphalt-temperature arithmetic behind the number, in our dogs on Phoenix trails guide.

Named trails, during an Extreme Heat Warning

A second and separate mechanism, which closes trails to everybody rather than just dogs. Verbatim from the same page:

"On days when the National Weather Service issues an Extreme Heat Warning, Camelback Mountain's Echo and Cholla Trails and all trails associated with Piestewa Peak Trailhead in the Phoenix Mountains Preserve and South Mountain Park and Preserve will close from 8 a.m. to 5 p.m."

8 a.m. to 5 p.m. on Extreme Heat Warning days. Those are the busiest trails in the city, and the closure window is most of the daylight hours.

At the time we read the page it also carried a dated banner: "Active until Saturday, August 29. For public safety, certain trails are restricted from 8 a.m. to 5 p.m." That is a seasonal notice, not a standing rule, so read the current banner rather than assuming those dates recur.

Any park or preserve the city chooses to close to dogs

This is the sleeper. Phoenix City Code 8-14(A), quoted in the Phoenix Police Department's leash law document, verbatim:

"Nothing in this section shall prevent the Director or the Parks and Recreation Board from prohibiting dogs or unrestrained dogs in a particular park, preserve or area under its jurisdiction, or any part thereof."

"Or any part thereof." So a single meadow inside a park can be closed to dogs without the park being closed. There is no central list of these decisions that we could find, which means signage at the entrance is the operative authority. Read it.

Off the lead, anywhere except a designated dog park

Not a place ban, but it functions like one, because the entire city outside a fenced dog park is leash-only.

City Code 8-14(A), verbatim from the same police document:

"No dog shall be permitted at large. Each dog shall be confined within an enclosure on the owner's or custodian's property, secured so that the dog is confined entirely to the owner's or custodian's property, or on a leash not to exceed six feet in length and directly under the owner's or custodian's control when not on the owner's or custodian's property."

Six feet maximum. A retractable lead extended beyond six feet is not compliant, and a dog on a long line in a city park is at large.

The state layers its own rule on parks and schools. ARS 11-1012(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 school property is on that list. School grounds are not a shortcut for a loose dog, even out of term.

Dog parks that are closed for the season

Phoenix runs fourteen dog parks. Ten of them have closure dates in the city's 2026 summer closure schedule, because the city rests the turf. That means a dog park you drove to may have a chain across the gate.

The city publishes the schedule as a document linked from its dog parks page. Check it before you drive. Our Phoenix dog parks guide walks the list and flags the four with no closure dates published, plus the ones with multiple pens that rotate rather than shutting entirely.

Note a discrepancy we could not resolve: the city describes the closure lengths in weeks in one place and gives specific dates in another, and for several parks the dates do not match the stated week count. Trust the dates on the schedule and, if you are making a long drive, the signage.

Inside a dog park, if the dog is under four months or unvaccinated

The fence being open does not mean your dog qualifies to be inside it. Verbatim from the city's posted dog park rules:

"Maricopa County requires that all dogs in the county be licensed. In addition to being licensed, dogs must be older than 4 months and be currently vaccinated."

Older than four months, licensed, and currently vaccinated. Note that the four-month figure conflicts with the three months in ARS 11-1008 and on the county's own licensing page. We print the set rather than reconciling it, and our Maricopa County dog licence guide lays out all four figures.

Two more exclusions, verbatim:

"Absolutely no female dogs in heat are allowed into exercise areas." "Dog behavior can be unpredictable around other dogs and strangers. For the safety of all the dogs at the parks, immediately leash your dog if it exhibits aggressive behavior and leave the dog park area."

The city also states that it "recommends that dog owners only bring animals that have been spayed or neutered", which is a recommendation rather than a rule.

Inside a dog park, with food

Worth its own line because it catches people out. Phoenix's posted dog park rules prohibit food inside the fence, and they require voice control rather than a lead.

That combination has a practical consequence: treat-based recall does not work in a Phoenix dog park. If your recall depends on a pouch of chicken, train it out before you go in, because you are relying on voice alone. Our dog park etiquette and how to leash train a dog guides cover the groundwork.

The rules also set a minimum age for children in the fence, which we cover in the dog parks guide.

Restrained outside during a heat or dust event

Phoenix's updated tethering ordinance restricts outdoor restraint during specific conditions rather than at specific places. The Council adopted it at its June 17, 2026 meeting and said it takes effect in approximately thirty days, so we are not printing an exact commencement date. Verbatim from the city's announcement: "Dogs may not be restrained outdoors at any time during extreme weather. This includes temperatures above 100 degrees, heat advisories, monsoon activity, or dust storm warnings".

The same ordinance requires direct supervision, which the city defines as keeping the dog within visual range at all times, and it reduced the minimum tether length from ten feet to six.

So a yard, a patio or a shopfront rail is off limits as a tether point on a hot afternoon. Full detail in our Phoenix dog tethering ordinance guide.

Loose on private property that is not yours

City Code 8-14(A) requires confinement "entirely to the owner's or custodian's property". And ARS 11-1012 has an at-large provision that a dog off its own land and off a lead falls under.

The practical version: a dog that wanders next door is at large, whether or not it left the block. Our Arizona dog laws guide covers the state statutes, including the strict-liability bite provisions that make this more than a technicality.

The short version

Check the thermometer first. At 100 degrees or above, every city trail is closed to your dog. That single rule accounts for more Phoenix "where can't I go" questions than everything else combined.

Then check the dog park schedule, because ten of fourteen have summer closures.

Then read the signage, because the Parks Board can close any park, preserve or part of one to dogs and there is no central list.

And keep the lead at six feet, on the assumption that anywhere outside a fenced dog park is leash-only. It is.

If you are visiting rather than living here, come between November and March. Our pet-friendly hotels in Phoenix roundup and Phoenix hotel directory cover where to stay, and our hotel stay with a dog packing list covers what to bring.

Frequently asked questions

Where are dogs banned in Phoenix? Dogs are prohibited on all City of Phoenix hiking trails when the temperature is 100 degrees or warmer. Separately, City Code 8-14(A) lets the Parks Director or the Parks and Recreation Board prohibit dogs in any particular park, preserve or area, or any part of one, so signage at the entrance is the operative authority.

Are dogs allowed on Camelback Mountain? Not at 100 degrees or warmer, under the city's trail rule. Camelback's Echo and Cholla Trails also close to everyone from 8 a.m. to 5 p.m. on days when the National Weather Service issues an Extreme Heat Warning.

How long can my dog's leash be in Phoenix? Phoenix City Code 8-14(A) sets a maximum of six feet, and requires the dog to be directly under the owner's or custodian's control when off the owner's property.

Can I take my dog off the lead in a Phoenix park? No, unless it is a designated dog park. City Code 8-14(A) prohibits a dog at large, and ARS 11-1012(D) requires physical restraint by a leash in a public park or on public school property.

Are Phoenix dog parks closed in summer? Ten of the city's fourteen dog parks have closure dates in the 2026 summer closure schedule. Check the schedule linked from the city's dog parks page before you travel.

Can I bring treats into a Phoenix dog park? No. The city's posted dog park rules prohibit food inside the fence, and voice control is required rather than a lead, so recall needs to work without treats.
