According to Chapter 828, what form of identification can be used for an animal that has been sterilized?

The correct identification method for an animal that has been sterilized, according to Chapter 828, is the microchip. Microchips are small devices implanted under the animal's skin that provide a unique identification number, which can be linked to the owner's information in a database. This method is widely recognized as a reliable and permanent form of identification.

While other options like a license tag or collar can indicate an animal's general compliance with local regulations or ownership, they do not specifically serve to identify an animal as having been sterilized. Papers from a veterinarian may provide proof of sterilization but are not a direct form of identification for the animal itself. The microchip's permanence and its ability to remain with the animal for life make it the most effective means of identification for a sterilized pet, as it cannot easily be lost or removed like a collar or tag.
