Training Whistle | Adjustable Frequency | Nickel Plated

The ACME Whistles Silent Dog Whistle is the ultimate tool for precision training across all breeds. Despite its name, no dog whistle is completely silent. Humans can hear only the faintest sound, while dogs hear a clear, loud tone that carries up to 1.5 km (over a mile). Designed with special air directors for tight frequency control, this whistle delivers consistent sound with minimal effort.

Its screw piston mechanism allows you to adjust the frequency to suit your dog’s unique hearing, making it one of the most versatile training whistles available. Crafted from solid brass, it is built to last for decades and retains its original Art Deco inspired shape created by Clifford Hudson, son of ACME’s founder. Each whistle includes a training guide with easy instructions for tuning and recall.

Ellie ★★★★★

My neighbor's dog used to bark at every passing squirrel, and this whistle got his attention in one quick blow. The adjustable tone lets me find the exact frequency he responds to, and it's small enough to clip right on my keyring. Two weeks in, it's already made our morning walks so much calmer.

John U. ★★★★★

My dog went deaf to my voice years ago, but this whistle cuts through everything—the adjustable pitch means I finally found the frequency she actually responds to. It's surprisingly light in my pocket too, barely notice it's there until I need it.

Evelyn ★★★★★

Took it to the park for the first time and my dog came running from across the field on the very first blow. The pitch adjustment range is way more than I expected, so I dialed it to something that doesn't hurt my ears at all. Training sessions just got a whole lot easier.
