About This

• ✅【ADJUSTABLE FREQUENCY DIAL】Twist the adjustment screw to tune across multiple ultrasonic frequencies. Each dog responds differently—test settings until you find the sweet spot where your dog reacts most strongly. One whistle, customized for your breed
• ✅【1000M LONG-RANGE RECALL】Ultrasound travels up to 1000 meters in open terrain. Train sit, paw, lay down, stay, and heel from a distance. Even when your dog disappears around a corner or across a field, one blow brings them back to you—no yelling required
• ✅【304 STAINLESS STEEL, BUILT TO LAST】Premium rust-proof metal construction stands up to aggressive chewers, rain, drops, and daily outdoor abuse. Ultrasound is completely safe—targets canine hearing without damaging eardrums or causing health issues.
• ✅【WORKS FOR ALL BREEDS】From Labradors and Golden Retrievers to German Shepherds, Beagles, and Scottish Terriers—every dog hears ultrasound. Puppies and seniors alike respond to consistent training.
• ✅【ANTI-LOSS LANYARD & LOCK NUT】Comes with a secure neck lanyard so your whistle stays put during active sessions. Special lock nut prevents accidental frequency drift mid-training. Take it hiking, to the park, or out on the farm—never misplace your training tool again
• ✅【SMALL, PORTABLE, READY TO GO】Compact size fits comfortably in your palm or pocket. No batteries, no apps, no charging—just blow and train. Consistent daily practice builds reliable obedience. Communicate clearly with your dog wherever life takes you
• ✅【STOP BARKING HUMANELY】Ultrasonic frequency grabs your dog's attention and interrupts excessive barking—whether it's your own pup or the neighbor's. Safe alternative to shock collars, no shouting required, perfect for apartments and shared walls
