A pet identification tag is a small, often metal or plastic tag attached to a pet's collar. It typically contains important information such as the pet's name, the owner's contact number, and sometimes the pet's medical needs. This helps ensure that lost pets can be quickly returned to their owners. These tags are essential for pet safety, as they provide a quick way for strangers to identify and contact the owner if the pet goes missing. Many pet owners also choose to include additional information, like the pet's microchip number, to enhance the chances of a safe return.
