Say it clearly, say it once.
Single Command- Repeating words over and over teaches your pet to ignore you. Read that again. It’s on you as the leader to develop the human skill of the saying the right time, the first time.
Tone- Listen to the way you speak to your pets: Are you speaking loud enough for them to hear you? Are you making a statement or asking a question? Practice being clear and confident with your words in training scenarios.
