HHSP Training Whistle — Ultrasonic Dog Command Tool

Your dog knows exactly what "come here" means. He's just pretending he doesn't. This ultrasonic whistle cuts through the selective hearing with a clear, consistent signal for recall, barking, and the basics — no yelling across the yard required. Pocket‑sized, so it's ready the moment he tests you.

• Ultrasonic tone he can't ignore (as easily)
• Great for recall, barking, and obedience basics
• Small enough to live in your pocket
