On a sunny day near Martinez, California, a friendly-looking German shepherd named Zinka rushes down the crisscrossing trails of Briones Regional Park wearing a vest covered in sensors, batteries and wires. She’s followed by her trainer, Shay Cook, who keeps up at the end of a long leash.

The duo trains to track people who have passed through an area — hours or even days later.

They also search for missing people lost in natural disasters like fires and earthquakes.
