As an owner, you know that your dog needs clear, unadulterated signals in a defined frequency range in order to understand your commands. ACME dog whistles send an understandable signal in a standardized frequency in every situation. Each dog whistle produces an absolutely identical signal to which the dog can be conditioned. You can reorder this dog whistle again and again, even after years.
