Bangkok residents who own dogs and cats are required to register and microchip their pets under a new city law that will come into effect on January 10 next year.

The animals must be chipped within 120 days of birth or 30 days of ownership.

The regulation also limits the number of pets allowed, depending on living space, and includes restrictions on the possession of dangerous breeds.

According to the new rules, for a living space of 20 to 80 square metres in an apartment or condominium, only one pet is allowed.

For an 80 square metre or more apartment or condominium, two pets are permitted.

For larger living spaces, up to three pets are allowed for areas of up to 50 square wah of land, four pets for up to 100 square wah, and not more than six pets for areas of 100 square wah and more.

Economic animals such as cows, horses, ducks, and chickens can only be kept in designated areas.

Owners of pets must register and microchip them within the specified timeframe, and those with dangerous breeds like pit bulls and Rottweilers must notify district authorities for special control.

The new regulation aims to address the issue of stray animals in the city.
