Summary

Every companion animal three months or older in Las Cruces must carry a registered identification microchip under Sec. 7-11, and the current registration on file stands as legal proof of ownership. Owners have 30 days to update the microchip registry after a move, a change of contact information, or a change in ownership.

A person owning or having care, custody, or control over a companion animal judged to be three months of age or older shall: (1)Have the animal implanted with an identification microchip, with current, up-to-date pet owner information, including the owner's/guardian's or community cat caregiver's name, address, and phone number. The current, up-to-date pet owner information associated with the microchip shall constitute proof of ownership for this chapter.

Full Breakdown

Sec. 7-11 requires anyone owning or having care, custody or control of a companion animal judged three months of age or older to have the animal implanted with an identification microchip carrying current owner or community cat caregiver information: name, address and phone number. That microchip registration record 'shall constitute proof of ownership' under the chapter, which matters directly in disputes over found or missing animals and in rabies exposure investigations handled by the animal control unit and the New Mexico Department of Health field office.

The owner must keep the microchip registration current with the registration company and has 30 days from any change of address or phone number to update it. When a microchipped animal changes hands, the previous owner is responsible for removing the animal from their own name and for re-registering the chip in the new owner's name within 30 days of the transfer; leaving an old registration in place can leave the wrong person on the hook when animal control traces the chip during a bite investigation, an impound or a found-animal claim.

The microchip requirement also underlies several other chapter 7 permits: an intact-animal permit under Sec. 7-31(11) cannot issue until the animal is microchipped, and a potentially dangerous or dangerous dog cannot be registered under Sec. 7-33 without a microchip on file with the animal control unit.

Violations & Fines

Failing to microchip a companion animal, or letting a chip registration lapse past the 30-day update window, is a violation of chapter 7 enforced by animal control citation, punishable under the chapter's general penalty section. A missing or outdated microchip registration also costs an owner the benefit of the doubt in a found-animal, missing-animal or bite-exposure case, since the current registration is what the ordinance treats as proof of ownership.

Frequently Asked Questions

At what age must my pet be microchipped in Las Cruces?
Sec. 7-11 applies once a companion animal reaches three months of age. From that point, the owner or guardian must have the animal implanted with an identification microchip and keep the registered contact information, including name, address and phone number, current with the microchip registration company.
How long do I have to update my pet's chip after I move?
30 days. Sec. 7-11(3) gives the owner or community cat caregiver 30 days from any change in address or phone number to update the microchip registration company's records, so animal control and any finder can still reach the current contact on file.
I just adopted a microchipped dog. What do I need to do?
The previous owner is responsible for removing their name from the chip, and the new owner must have the registration transferred within 30 days of the change in ownership under Sec. 7-11(4). Until that transfer happens, the old registration remains the proof of ownership the animal control unit relies on.
