Which of the following is NOT necessary for a public demonstration involving canine handlers?

A list of previous demonstrations is not typically necessary for a public demonstration involving canine handlers. While it can provide context or credibility for the handlers and their techniques, the primary focus of a demonstration is on the current event and the performance of the canine team in the present moment.

Approval from management is essential, as it encompasses the authorization to use specific facilities and resources, ensuring that all safety and procedural protocols are met. Details about the audience size are also important for planning purposes, allowing the handlers to appropriately prepare for crowd control and the visibility of the demonstration. Additionally, knowing the specific date and time helps in organizing logistics and ensuring that all participants are available and prepared. In contrast, prior demonstration records, while potentially beneficial for historical insight, do not significantly impact the success of the planned event.
