Scottsdale vs Phoenix Dog Rules: Same County, Different City

Ten degrees, ten dog parks, a four-dog cap and a trail where the answer is always no. Every difference between the two cities, and everything that is identical.

Scottsdale and Phoenix share a state, a county, a licence, a shelter and a rabies ordinance. Everything that differs is city-level, and the differences are bigger than the shared border suggests.

The headline: Phoenix bans dogs from all its hiking trails at 100 degrees. Scottsdale tells you 90 is too hot, and bans dogs from one trail at any temperature.

Here is the whole comparison, layer by layer.

What is identical

Both cities sit in Maricopa County and under Arizona law, so all of this is the same on either side of the line.

The licence. Maricopa County issues it: $22 for a spayed or neutered dog, $55 intact, $10 for an altered dog where the owner is 65 or older, and late fees of $3 or $6 a month. The county's own page also says licences "start at just $19", which conflicts with its own table.

The shelter and the hold clock. Maricopa County Animal Care and Control, with a minimum 72-hour stray hold under Ordinance P-13 and a minimum 120-hour Hold-Notify for a licensed dog.

The bite quarantine. P-13 Section 9 puts a licensed and vaccinated dog at home and an unlicensed or unvaccinated one in a pound, or a vet hospital at your expense, for not less than seven days.

The bite liability. ARS 11-1025(A) makes the owner liable "regardless of the former viciousness of the dog or the owner's knowledge of its viciousness", and its subsection (C) bars breed from being considered by any court or hearing officer deciding whether a dog is aggressive or vicious.

The state leash and tag rules. ARS 11-1012 requires a lead in a public park or on public school property, a six-foot limit in a rabies quarantine area, and a tag on any dog over three months at large.

And the heat physics. Maricopa County's asphalt table applies to both: 77 degrees of air gives 125 degrees of asphalt, 102 gives 167, and "Skin damage can occur in ONE MINUTE when asphalt temperatures are above 125 degrees."

Our Maricopa County dog licence and Arizona dog laws guides cover the shared layers in full.

The temperature difference, and which is stricter

This is the one that changes your week.

Phoenix, verbatim from the city's heat safety page: "Did you know that dogs are prohibited on ALL city hiking trails when the temperature is 100 degrees or warmer?"

Scottsdale, verbatim from the Preserve page, split across two lines: "If it is over" / "90 degrees at any time in your hike, it's too hot for your dog."

Ten degrees apart, and different in kind. Phoenix's is a prohibition with a number. Scottsdale's is guidance with a lower number and a warning attached, verbatim: "The desert heat can kill them with little or no warning, and you could be charged with animal cruelty under State law."

Which is stricter depends on how you count. Scottsdale's threshold is lower and its wording is advisory. Phoenix's is higher and enforceable as a trail rule.

Practical answer for a dog owner: use 90 in both cities. No source we read suggests a dog is fine at 95 degrees in Phoenix, and the county's asphalt figures put the surface well past skin-damage territory long before either threshold.

Our Scottsdale dog heat rules and Phoenix dog heat rules guides cover each city's version, including a first aid conflict between Scottsdale and the county about cooling a dog with water.

The trail difference

Phoenix closes all city trails to dogs above a temperature. Below it, its trails are open on a six-foot lead.

Scottsdale closes one trail to dogs permanently. Verbatim from the Pinnacle Peak Park page: "Hiking with your dog and biking are not allowed on the trail. These activities are permitted at the nearby Brown's Ranch Trailhead ."

And the alternative it names is closed for improvements, with an expected start of 13 July 2026 and completion in Fall 2026.

Scottsdale's Preserve is the larger playground when it is cool enough: more than 30,500 acres and over 230 miles of trail, against Phoenix's mountain preserves. But it comes with the handheld lead rule and a waste rule that prohibits leaving a bagged pickup on the trail. Our Pinnacle Peak Park and dogs and dogs in the McDowell Sonoran Preserve guides cover both.

The dog park difference

Phoenix has fourteen. Scottsdale has four. But the four are better documented and better designed for a nervous dog.

Scottsdale's Active and Passive pens are the thing Phoenix does not publish. Two of its four parks split the space by temperament, with a third cell resting on rotation.

Phoenix rests entire parks for weeks in summer. Ten of its fourteen have summer closure dates. Scottsdale rests cells within a park, and closes the fenced areas for a four-hour window twice a week. For a dog owner planning a Tuesday morning, that is a much smaller disruption.

Two rules go opposite ways. Scottsdale caps you at four dogs per visitor, which Phoenix does not do at all. Phoenix bars children under 12 outright, while Scottsdale admits under-16s accompanied by an adult.

And one rule is the same in both: no food inside the fence, voice control instead of a lead. So treat-based recall works in neither city.

Our Scottsdale dog parks and Phoenix dog parks guides have both lists.

The tethering difference

Phoenix has an ordinance. We found none for Scottsdale.

Phoenix's Council adopted changes on 17 June 2026 making it unlawful to confine a dog using a tether, trolley or similar device unless the dog is under direct supervision, defined as within visual range at all times, and prohibiting outdoor restraint during extreme weather including temperatures above 100 degrees, heat advisories, monsoon activity or dust storm warnings. It also cut the minimum restraint length from ten feet to six.

We found no Scottsdale equivalent, and we cannot rule one out. Absence of evidence here is exactly that, and our Phoenix dog tethering ordinance guide covers what Phoenix did.

The penalty difference, which is really a readability difference

Phoenix's penalty ladder is public, because the Police Department publishes a PDF quoting City Code 8-14 in full: a Class 1 misdemeanour for the leash or tag subsections, a civil violation capped at $250 where the dog was tagged, escalating floors of $100 and $500 for repeats within 24 months, and $5,000 plus five days' imprisonment where the dog was previously determined vicious.

Scottsdale's is not. The one city rule we can quote is the leash sentence Scottsdale publishes on its own dog parks page, citing Ch. 20 Sec. 20-32.

So a Scottsdale owner asking "what is the fine" has to ask the city. That is a genuinely worse position than a Phoenix owner is in, and it is a property of the publishing platform rather than of the law. Our Phoenix dog fines and penalties guide covers the readable ladder, and the county's Class 2 misdemeanour ceiling for at-large violations in unincorporated areas applies outside both cities.

Where Scottsdale is clearly ahead

The anti-venom clinic list. Scottsdale publishes the nearest veterinary clinics to each Preserve trailhead and states which hold rattlesnake anti-venom on site. Two of the five day clinics say they hold none. Nothing comparable exists for Phoenix, and our rattlesnake bites and dogs in Scottsdale guide sets it out.

Published gate hours. The Preserve's open and close times are tabulated by date, from a 7:02 a.m. opening on 1 January to 4:47 a.m. on 15 June.

And published dog park hours and maintenance windows, which Phoenix does not match in the same form.

Where Phoenix is clearly ahead

Volume. Fourteen dog parks against four.

A readable code, at least for the leash chapter and the penalty ladder.

An enforceable trail rule rather than guidance, and a tethering ordinance that regulates extreme weather explicitly.

And a 24-hour vet directory published by the county covering the whole metro area, which serves Scottsdale owners too. Our emergency vets in Phoenix and emergency vets in Scottsdale guides both draw on it, and the Scottsdale one covers three hospitals whose names differ between the city and county lists.

If you are moving between the two

Your licence follows you. It is a county licence, so a move from Phoenix to Scottsdale needs no new paperwork.

Your leash habits do not change. Six feet in both, handheld in the Preserve.

Your summer routine does. Phoenix summer means dog parks minus the ten on closure. Scottsdale summer means four parks, two of which open at 5:30 a.m., with twice-weekly four-hour maintenance windows.

And your trail plan changes twice. Lower threshold in Scottsdale, and one park where the answer is always no.

Our moving to Scottsdale with a dog guide sequences an arrival, and our Phoenix hotel directory and pet-inclusive apartments in Phoenix listings are the nearest PetCompass directories to both cities.

Frequently asked questions

Are Scottsdale and Phoenix dog rules the same? No. They share the state statutes, the Maricopa County licence, the county shelter and the county rabies ordinance, but each city writes its own leash, park and heat rules and those differ.

What temperature closes trails to dogs in each city? Phoenix prohibits dogs on all city hiking trails at 100 degrees or warmer. Scottsdale's Preserve guidance is that over 90 degrees at any time during the hike is too hot for the dog.

Which city is stricter about heat? Scottsdale uses a lower number but publishes it as guidance. Phoenix uses a higher number but publishes it as a prohibition. For a dog, the safer working figure is 90 in both.

Do I need a new dog licence if I move from Phoenix to Scottsdale? No. Licensing is at county level through Maricopa County and covers both cities.

How many dog parks does each city have? Scottsdale has four. Phoenix has fourteen, ten of which have summer closure dates.

Which city separates dogs by temperament in its parks? Scottsdale. Two of its four dog parks are divided into three areas, with one designated for Active Dogs, another for Passive Dogs and a third closed on rotation for maintenance.
