Method and system for tracking animals and alerting animal owners of lost animals

A computer system for tracking a companion animal and alerting an owner of the companion animal when the companion animal is lost, the computer system comprising:

• a server generating a web page associated with a near-field-communication (NFC) portion of an electronic tag, the electronic tag being coupled to the companion animal;
• the server generating a geo-fence associated with the electronic tag;
• the server monitoring the geo-fence to determine if the electronic tag has exited the geo-fence;
• the server sending a message to the web page if the electronic tag has exited the geo-fence;
• the server sending an alert to a portable computing device if the electronic tag has exited the geo-fence;
• the server sending a command to the electronic tag to change from a first rate to a second rate for a device identifier reporting rate;
• the server sending a command to the electronic tag to report its present battery level status to a communications network, the electronic tag further comprising a low power wide area (LPWA) portion;
• the server receiving a request from the communications network an increased frequency of reporting for a location of the electronic tag;
• and the server sending a command to the electronic tag to change the second rate to a third rate for sending the device identifier to the communications network.
