ACME Dog Whistle #535
This is an Acme Silent Dog Whistle that is designed to be “silent” but not completely. You can can hear it, but only just. You might not be able to hear it but your dog can hear it very clear and loudly (up to 1.5km in distance). You can adjust the frequency of the whistle by using a screw piston mechanism allowing you to tune it to accustom your dog. This whistle can be used for all dog breeds. Perfect for training your dog in no time!
