Summary

Pima County does not require residents to spay or neuter pets they already own. Its mandatory sterilization rule applies specifically to dogs and cats adopted out of the Pima Animal Care Center: every animal must be spayed or neutered and microchipped before release, unless a veterinarian certifies a medical reason to wait.

City-specific rules exist: Tucson has its own mandatory spay/neuter rules that differ from Pima County's county-level regulations. If you live in Tucson, check the city-specific page instead.

A. Any dog or cat held by the Pima Animal Care Center for the period required by law and not reclaimed by its owner may be released for adoption subject to the following conditions: 1. The adopting owner must pay a fee pursuant to Section 6.04.060. A transportation fee of no more than six dollars per dog or cat may also be charged to adoption owners. 2. Pima Animal Care Center will insure that all such animals are spayed or neutered and microchipped prior to release to the adopting owner unless the veterinarian determines that the animal has medical contraindications that would prevent or require postponement of surgery. 3. If the veterinarian determines that medical contraindications for surgery exist that would require postponement of surgery, a spay/neuter certificate will authorize postponement of the surgery until such time that the veterinarian determines that surgery can be performed in a safe, humane manner.

Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2026 S-64: Contains Supplement, with local legislation through Ordinance 2026-9, passed 7-28-2026, current through 7-28-2026).

Full Breakdown

090 governs unclaimed dogs and cats held at Pima Animal Care Center (PACC) past the legally required holding period. 060, plus an optional transport fee capped at $6 per animal. Subsection A(2) is the sterilization mandate itself: PACC must ensure every adopted dog or cat is spayed or neutered and microchipped before it leaves the shelter, unless a veterinarian finds a medical contraindication that prevents or requires postponing surgery. When that happens, A(3) lets the vet issue a spay/neuter certificate authorizing postponement until surgery is safe.

If the vet later determines the animal is permanently disqualified from surgery and remains capable of reproducing, A(4) requires PACC to take the animal back, cancel the adoption, and refund the adopter's fees in full. A(5) puts the burden on the adopting party to bring the animal back for surgery as the vet directs; skipping that step triggers an extra-board charge, and an animal left unclaimed can be declared abandoned. Subsection B requires every adopter to sign a hold-harmless agreement protecting the county, its officers and employees from claims arising out of the adoption program. Nothing in this section reaches privately owned pets that were never surrendered to or adopted from PACC.

Violations & Fines

There's no criminal penalty attached to this section; the consequences run against the adopting party's arrangement with the county. An adopter who fails to return a postponed-surgery animal as directed is charged extra board fees, and PACC may declare the animal abandoned. If a vet permanently disqualifies the animal from surgery, PACC reclaims the animal, voids the adoption, and refunds the adopter's fees under § 6.04.090(A)(4).

Frequently Asked Questions

Does Pima County require me to spay or neuter my own dog or cat?
No. Section 6.04.090 only governs animals adopted from the Pima Animal Care Center. It has no application to pets you already own and never surrendered to the county shelter; Pima County has no county-wide mandate reaching privately owned, unadopted animals.
What if my newly adopted pet has a medical reason it can't be fixed yet?
A veterinarian can issue a spay/neuter certificate under § 6.04.090(A)(3) authorizing postponement of surgery until the vet determines it can be performed safely. The animal still must go home already microchipped under the general condition in A(2).
What happens if I don't bring my adopted pet back for its surgery?
Under § 6.04.090(A)(5), failing to reclaim the animal for surgery as the veterinarian directs results in an extra board charge, and an unclaimed animal can be declared abandoned by Pima Animal Care Center.
Can the county cancel my adoption after the fact?
Yes, but only if a veterinarian determines your adopted animal is permanently disqualified from surgery and remains capable of reproducing. Section 6.04.090(A)(4) requires the animal's return, cancels the adoption, and refunds all fees you paid.
