Dogs over the age of 2 months must be registered. There are two ways to register your dog: internal and external. Failure to register an animal can result in a fine of up to KRW 1 million. Dogs kept in houses or semi-houses and dogs over 2 months old kept for companionship in other places are subject to animal registration. If you produce, sell, or import an animal subject to registration, you must notify the buyer how to register the animal and apply for local government animal registration.
