Dallas County has no microchip ordinance, and Texas does not require microchipping pets. Cities choose their own rules; Dallas mandates microchips for dogs and cats under Chapter 7. Voluntary chipping is strongly encouraged for return-to-owner.
Texas state law does not require microchipping for companion animals. Dallas County itself imposes no microchip rule, leaving the question to municipalities and individual owners. Dallas City Code Chapter 7 requires every dog and cat over four months to be microchipped and registered, with the chip number on the city license. Surrounding suburbs vary: some pair microchipping with licensing or shelter intake; others rely entirely on voluntary chipping. Dallas County HHS, SPCA of Texas, and city shelters routinely offer low-cost microchip clinics. Universal scanners at every intake shelter mean a registered chip dramatically improves the chance of reunion after a stray pickup.
There is no county penalty. Where cities require microchips, citations typically run from fifty to several hundred dollars per offense, and unchipped animals impounded at municipal shelters may face higher reclaim fees and mandatory chipping at owner expense.
