In the video, a person is seen holding a stethoscope and placing it on a dog's back. The person then begins to listen to the dog's heartbeat. The dog appears to be calm and relaxed during the process. The person's hands are steady as they hold the stethoscope in place, indicating that they are likely a veterinarian or someone trained in animal health. The dog's coat is a light brown color, and it seems to be a medium-sized breed. The background is not clearly visible, but it appears to be an outdoor setting.
