Acme's Silent Dog Whistle, made in England since 1935, is the perfect dog training whistle
for town or country, close or distance work. It offers an adjustable frequency range, from 5400
Hz to 12,800 Hz, that can be tuned to your dog's hearing, making it the most effective way for
trainers to communicate with their dogs. Made of lightweight, durable stainless steel, the
whistle's sound is barely audible by humans but can be heard by dogs over great distances.
The excellent design of this whistle includes a handy cap attached by a lightweight chain.
