Usage
Designed for both professional trainers and everyday pet owners, this whistle excels in a variety of real‑world scenarios. Whether you are attempting to curb incessant barking during a neighbor’s gathering, reinforcing recall commands on a hiking trail, or teaching a new trick at home, the adjustable ultrasonic tone can be set to an audible or silent mode to suit the environment. The silent mode emits a frequency beyond human hearing, allowing discreet correction without drawing attention, while the audible mode provides a clear cue for dogs that respond better to audible signals.
Because the frequency can be customized, owners can experiment to discover the exact pitch that captures their dog’s focus, a feature especially valuable for multi‑dog households where each canine may have a unique response pattern. The compact size and lanyard attachment make it easy to keep the whistle within reach, ensuring you can intervene the moment unwanted behavior arises.

FAQ
How do I adjust the frequency on the whistle?
Turn the small screw located on the side of the whistle clockwise to raise the pitch or counter‑clockwise to lower it. Test the tone by blowing gently; you will hear a change in the sound that indicates the new frequency setting.
Is the ultrasonic sound safe for my dog?
Yes. The whistle emits frequencies that are high enough to attract attention but are calibrated to avoid causing hearing damage. It is designed for short, corrective bursts rather than prolonged exposure.
Can the whistle be used for multiple dogs?
Absolutely. Because each dog may respond to a different pitch, you can adjust the frequency for each individual. The 2‑pack allows you to set one whistle for one dog and the other for a different dog, or keep a spare on hand.
What is the difference between audible and silent modes?
Audible mode produces a sound that humans can hear, useful for training sessions where you want a clear cue. Silent mode emits an ultrasonic tone only dogs can hear, allowing discreet correction without drawing attention from people nearby.
Do you offer a warranty or return policy?
Yes. The whistle comes with a one‑year limited warranty covering manufacturing defects. If you encounter any issues, contact our support team for a replacement or refund according to our return policy.
