Bangkok to Require Microchipping for All Dogs and Cats by 2026

Bangkok: Pet owners in the capital will soon be required to register and microchip their cats and dogs under a new municipal law aimed at improving public health and reducing the stray animal population.

The Bangkok Metropolitan Administration (BMA) announced that starting January 10, 2026, all domesticated cats and dogs must be microchipped and registered with local authorities. The regulation, published in the Royal Gazette earlier this year, grants pet owners ample time to comply.

Under the new policy:

• Animals must be microchipped within 120 days of birth or within 30 days of adoption.
• Households living in apartments or condominiums under 80 square metres will be allowed to keep only one pet.
• Residences over 80 square metres may house up to two pets.
• In detached homes, the permitted number of pets ranges from two to six, depending on the size of the property.
• Livestock, including chickens and cattle, will be restricted to designated agricultural areas.

City officials say the regulations are part of a broader public safety initiative. In addition to preventing abandonment and managing animal populations, the system is expected to help authorities trace lost or mistreated animals more efficiently.

Additional Rules for Dangerous Breeds

Owners of dog breeds classified as "dangerous" (including pit bulls and Rottweilers) will be required to report their pets to local district offices. These animals will be subject to further supervision, although details of the additional measures have not yet been released.

While the BMA has yet to clarify the penalties for failing to comply with the new rules, enforcement is expected to begin in earnest once the grace period ends.
Veterinary clinics and animal welfare groups have urged residents to begin preparations early to avoid a last-minute rush.

Pet owners are encouraged to consult their local district office or veterinary provider for guidance on microchipping procedures and registration requirements
