ACME Thunderer Dog Training Whistle

The ACME Thunderer Dog Training Whistle is one of the most recognisable and trusted whistles in the world of dog training — a robust, loud, and weatherproof pea whistle used by handlers and trainers across all disciplines for over 150 years. Made in Birmingham, UK, since 1870.

The Thunderer produces a powerful, penetrating blast that carries clearly across open ground, into heavy cover, and over wind and water — essential for handlers who need reliable, long-distance communication with their dog. Compression-moulded from tough, bite-resistant plastic, it's built to withstand hard daily use in all conditions.
