What is the requirement for the jury's signal at a go-to-ground event?

In a go-to-ground event, the requirement for the jury's signal is crucial for maintaining a fair and organized competition. The correct answer emphasizes that the event officially begins only when the judge gives a signal. This ensures that all participants, including handlers and dogs, are prepared and aware that the competition is starting.

When the judge signals, it indicates that the time and conditions are right for the dog to enter the tunnel, allowing for a consistent experience among all competitors. This clarity helps prevent confusion and ensures that the performance of each dog is evaluated under the same parameters.

While other elements, such as when the dog enters the tunnel or when the handler is ready, are important for the event's flow, they rely on the judge's signal to commence the action properly. Thus, the requirement for the jury's signal is essential for maintaining the structure and integrity of the event.
