Found a Loose Horse in Arizona? What the Law Says

The short answer: If you found a loose horse in Arizona, state law gives you two choices: try to find the owner and tell them where the horse is, or notify the Arizona Department of Agriculture. Horses count as livestock under Arizona law. If the owner cannot be found, a livestock officer holds the animal at least seven days, and up to fourteen on request, then sells it at public auction after at least five days' notice. The owner can reclaim it before the sale by proving ownership and paying the costs.

Every horse neighborhood has the story. You are out early with your coffee, and there is a bay gelding in your front yard, eating your roses, looking very proud of himself. If you live on horse property in the Metro Plex of Arizona long enough, you will be the one who found a loose horse in Arizona, and someday, maybe the one looking for yours. Here is the good news: Arizona has a simple, neighborly process for it.

Everything below comes from Arizona Revised Statutes Title 3, read on the Arizona Legislature's website this week.

Yes. A.R.S. 3-1201 defines livestock as "cattle, equine, sheep, goats and swine, except feral pigs." Equine means horses, so the stray livestock rules apply to a loose horse.

A.R.S. 3-1401 defines a stray animal as livestock "whose owner is unknown or cannot be located," or livestock whose owner is known but "permits the animal to roam at large on the streets, alleys, roads, range or premises of another without permission." There is an exception where a federal permit, allotment or lease is in dispute, which mostly matters on range land.

A.R.S. 3-1402(A) gives you two paths:

1. Find the owner. You may try to locate the owner and, if you find them, tell them where the horse can be found.
2. Call the state. If the owner is unknown or cannot be located, or you choose not to look, you "shall notify the department," meaning the Arizona Department of Agriculture.

Practically, here is what I do, and what my neighbors do:

• Make it safe first. If the horse is near a road, calmly guide it into a safe pen or catch it with a halter if you can do so safely. Your safety comes first.
• Give water. A loose horse has usually been on an adventure.
• Ask around. Knock on a few doors, text your neighborhood group, and post a clear photo on local horse community pages.
• Look for clues. A halter tag, a brand or a freeze mark can lead you right to the owner.
• Call the Department of Agriculture if the owner does not turn up.

A.R.S. 3-1402(B) says a livestock officer or inspector will try to locate the owner. If the owner does not take immediate possession, or cannot be found, the officer holds the animal "for at least seven days," and up to fourteen days at the request of any person or organization. Then the animal is sold at public auction to the highest bidder for cash, after at least five days' notice.

Subsection C says notice of the sale is posted in three public places in the justice precinct where the animal is held, stating where the animal is held and where it will be sold.

Yes, and the law gives owners two chances. Under subsection D, the owner can take the horse back "at any time prior to sale" by proving ownership and paying the inspection fee and the costs of keeping and caring for the animal.

Under subsection E, even after a sale, the owner can reclaim the horse at any time before the purchaser sells it, by paying the purchaser the price they paid plus the expense of keeping and caring for the horse since the sale.

That is why proof of ownership matters so much. Keep your bill of sale, registration papers, brand inspection paperwork and clear photos of each horse somewhere easy to grab. Our guide to Arizona horse brand inspection explains the paperwork side.

No. The statute gives you the two paths above: find the owner, or notify the department. Keeping a found horse is not one of them. Doing it the right way protects you, the horse and the owner.

That depends on where you live and on Arizona's fence and open range rules, which are a separate topic. Our guide to Arizona open range law and who pays for the fence covers how it works.

Prevention is the happiest part of this story. A few habits that work:

• Walk your fence line after storms and every few weeks.
• Use self-closing or chained gates, and double-check them at night feeding.
• Choose the right fence for your horses and your land. Our guide to horse fencing types compared for Arizona helps.
• Put a tag on every halter with your phone number.
• Keep current photos of every horse, both sides, with markings visible.

• Chasing it. A calm approach works far better than running after a horse.
• Not calling anyone. If you cannot find the owner, the law says notify the department.
• Keeping it. That is not one of the options in the statute.
• Owners with no proof of ownership. Papers and photos make reclaiming fast.

What do I do if I find a loose horse in Arizona? Try to find the owner and tell them where the horse is, or notify the Arizona Department of Agriculture if the owner cannot be found.

Is a horse considered livestock in Arizona? Yes. A.R.S. 3-1201 defines livestock to include equine.

How long does Arizona hold a stray horse? A livestock officer holds it at least seven days, and up to fourteen days on request, before a public auction with at least five days' notice.

Can the owner reclaim a stray horse after it is sold? Yes, before the purchaser resells it, by paying the purchase price plus the cost of care since the sale.

Can I keep a stray horse that wanders onto my property? No. The statute's options are to locate the owner or notify the Department of Agriculture.
