Acme Silent Dog Whistle

The Acme Silent Dog Whistle 535 is one of the world's most recognised professional dog training whistles, trusted by gundog handlers, working dog trainers and pet owners for generations. Originally invented by Acme in 1935, this precision-engineered whistle produces an adjustable high-frequency tone that is only faintly audible to most people but carries clearly to dogs over long distances, making it ideal for discreet and effective training.

Despite its name, no dog whistle is completely silent. Instead, the Acme 535 emits a very high-frequency sound that dogs hear extremely clearly while remaining barely noticeable to the human ear. Using its precision screw piston adjustment, you can fine-tune the frequency to suit your individual dog's hearing and then maintain that same tone for consistent recall and obedience training. The whistle covers an adjustable frequency range of approximately 5,400Hz to 12,800Hz, making it suitable for virtually all breeds.

Designed with Acme's unique air director system, the Silent Dog Whistle delivers outstanding sound projection with minimal effort. Under suitable conditions, the signal can travel up to 1.5 kilometres, making it an excellent choice for field work, gundog training, long-distance recall and everyday obedience exercises. Every whistle is supplied with easy-to-follow training instructions to help establish reliable whistle commands.

Manufactured from solid brass with a durable nickel-plated finish, the Acme 535 combines classic styling with exceptional longevity. Its robust construction has made it a favourite amongst professional trainers for decades, while the compact design makes it easy to carry in a pocket, game bag or on a lanyard during training sessions.
