Online Dog Whistle

It depends on the frequency! Humans can typically hear up to 20,000Hz (20kHz), but this upper limit decreases significantly with age. Most adults over 30 cannot hear above 15kHz-16kHz. Dogs, however, can hear up to 45,000Hz. If you set the tool to 22kHz, your dog might perk up or tilt their head while you hear absolutely nothing. This 'silent' nature is what makes dog whistles so useful for public training.

It can work as an effective 'interrupter'. When your dog starts barking excessively, play a short high-frequency burst (around 15kHz-25kHz). The sudden, novel high-pitched sound usually startles them into silence. You must then IMMEDIATELY praise the silence or redirect them to a positive behavior. The whistle itself is not a magic cure; it is a tool to break the fixation so you can train.

Yes, as long as the volume is reasonable and not played for extended periods. Think of it like a normal whistle—it's annoying but not harmful at normal levels. However, ultrasonic sounds can be very loud to dogs even if silent to you. Do not place speakers directly against a dog's ear, and use the 'Timer' feature to prevent leaving it on accidentally. Always start at a lower volume.

Lower frequencies that humans can also hear (12kHz - 15kHz) often travel further and are easier for dogs to localize than pure ultrasonic tones. However, the 'best' frequency is simply the one your dog responds to best. Consistency is key: Pick one specific frequency (e.g., 14,000 Hz) and stick to it so your dog recognizes that specific pitch as their 'come' command.

Two common reasons: 1) The frequency is above your personal hearing range (very common for adults). 2) Your device speakers may not be capable of playing ultrasonic sounds. Most phone and laptop speakers drop off significantly above 18kHz-20kHz. For the best training results, use high-quality external speakers or Bluetooth speakers that have a wider frequency response range.

Yes! Cats actually have even better hearing than dogs, hearing up to 64,000Hz. You can use the whistle for clicker-style training with cats, or to deter them from scratching furniture (as an interrupter). Even rodents like hamsters and guinea pigs can hear ultrasonic frequencies, so be mindful if you have small pets in the room.

The 'Pulse' mode emits a rhythmic beep-beep-beep pattern instead of a continuous tone. This is often more effective for capturing attention or acting as a 'Clicker' replacement. Continuous tones are better for 'Stop' or 'Freeze' commands, while pulses are excellent for 'Come' or 'Look at Me' signals.

Set the whistle to a short, distinct frequency (e.g., 10kHz or 12kHz). Use the keyboard shortcut (Spacebar) to trigger a very short burst (0.5s) the exact moment your dog performs the desired behavior (like sitting). Follow immediately with a treat. The sound becomes the 'Bridge' or 'Marker' that tells the dog 'You did it right, reward is coming'.

Yes! This dog whistle tool is a Progressive Web App (PWA) built with local browser technologies. Once the page is loaded, the sound generation happens entirely on your device. You can use it in the park, on a hike, or anywhere without an internet connection.

Your dog may be sensitive to the sound or the volume is too high. Stop immediately. Turn the volume down and try a lower frequency. The goal is to get their attention, not to scare them. Pair the sound with high-value treats so they associate the noise with something positive, rather than something scary.
