True or False: In obedience exercises, when instructed to "fast," the dog only needs to change pace.

In obedience exercises, the command to "fast" implies that the dog should not only change its pace but also adjust its overall posture and energy level. This instruction typically means that the dog should move at a quicker speed and may need to exhibit more enthusiasm and alertness in its movements. Simply changing pace does not fully encompass the expectations associated with the "fast" command.

For a dog to respond effectively to "fast," it should also show a readiness to follow the handler's lead, maintaining focus and control while speeding up. This is important for demonstrating the dog's ability to follow commands accurately and participate actively in the exercise.

While some other commands might only require a pace change depending on the context or the specific exercise, the general understanding of "fast" necessitates a more comprehensive response from the dog, making it clear why the statement is false.
