Acme 535 Silent Dog Whistle Lanyard often worn around the neckNo "silent" dog whistle is truly silent. If it were, nothing would be able to hear it! The word silent is written in inverted commas because you can hear it, BUT only just. What your dog hears is really loud and travels up to 1. 5km. Adjustable through a wide range of frequencies using a screw piston mechanism enabling you to tune it to suit your own dog, this is the most versatile silent dog whistle that can be used with all breeds.
