Omnipet Acme Silent Dog Whistle

The Omnipet Acme Silent Dog Whistle (SKU: OP535) is a precision training instrument designed for dog handlers, trainers, and working dog operators who demand reliable, distraction-free communication in high-noise environments. Unlike standard audible whistles that carry across neighborhoods and alert unintended targets, this silent whistle operates at frequencies inaudible to human ears while remaining within the canine hearing range—making it an essential tool for obedience training, recall work, and tactical canine operations where stealth and subtlety matter.

Manufactured by Leather Brothers Inc. under the Omnipet brand (UPC: 717668115358, MPN: 535), this whistle features a compact aluminum construction measuring 2.75 x 0.5 x 5.25 inches and weighing just 0.11 lbs, making it lightweight enough for attachment to gear or a training belt. The whistle produces ultrasonic frequencies—typically between 23–25 kHz—that dogs respond to instinctively without the acoustic bleed that compromises covert operations or disturbs neighboring properties. Its durable build withstands field use, weather exposure, and repeated deployment, while the silent operation principle eliminates handler fatigue associated with repetitive vocal commands or audible whistle blasts.

Professional dog trainers, law enforcement K-9 units, military working dog handlers, and serious obedience competitors benefit most from this tool's precision and discretion. It pairs seamlessly with any canine training protocol—from foundational sit-stay commands to advanced off-leash recall in open terrain—and requires no special equipment or calibration. The Omnipet Acme Silent Dog Whistle works effectively on all dog breeds and sizes, making it a universal solution for handlers seeking silent, consistent communication without environmental disruption or listener fatigue.
