How to use

Hold the whistle between your fingers and position it just outside your mouth. Use short, consistent bursts or single long notes depending on the signal you want to teach. Combine whistle cues with established verbal commands and rewards during training sessions to create a clear association for the dog. Start training at short range and gradually increase distance as the dog learns to respond reliably to the whistle.

Usage recommendations

Use the whistle at a moderate volume when first introducing the cue to avoid startling the animal. Keep sessions brief and consistent, and pair whistle signals with positive reinforcement. Store the whistle in a dry place and rinse with clean water if exposed to dirt or moisture; avoid harsh chemicals during cleaning.
