What the signal is for
Dogs Trust describes a marker as a signal that tells the dog it got something right and that a reward is about to follow. A word such as Yes or Good can serve as a marker. The point is clarity about the behavior, not a special word with automatic power.
A marker is not the reward itself
Dogs Trust says the marker should be followed by the reward so the dog can trust what the signal predicts. Discuss the sequence with your trainer and practice the human movements first if helpful. Changing a word, moving a hand and searching for a treat at once can make your own timing harder to follow.

Do not add noise to solve confusion
Repeating signals more loudly is not a substitute for a clearer task or a calmer setting. AVSAB distinguishes reward-based methods from aversive methods that use fear or pain. If a dog is not engaging, pause rather than invent a startling correction. Seek professional support when the situation is difficult or unsafe.
Write a cue agreement
Use the cue notebook to describe which word or gesture your household intends to use and what observable behavior it means. The notebook is an original coordination aid, not proof that the dog understands the cue. Keep a separate note for what actually happened and where. Do not enter names or personal information.
