The correct answer is that the time starts and ends when the dog crosses the line or activates the timer. In G-T-G (Go-To-Ground) events, timing is crucial for determining the efficiency and performance of the dog in completing the task. The start of the time is specifically tied to the dog's physical action, which ensures that the clock accurately reflects the time taken for the dog to engage with the challenge.

When the dog crosses the line or activates the timer, it indicates the beginning of the task, while the end time is marked once the task is completed. This method of timing focuses on the dog's performance and results, providing a clear metric for assessing how quickly and effectively the dog operates within the course. By grounding the timing to the dog’s actions, it allows for a fair and consistent evaluation of all participants in the event.
