Dog Whistle Online

Dogs are most sensitive around 8,000 Hz, but can hear from 40 Hz up to 65,000 Hz. Professional dog whistles (like ACME) typically use 5,200–6,200 Hz for best range and response.

Frequencies above 16–18 kHz are inaudible to most adults, but dogs hear them clearly. Note: most phone and laptop speakers cannot physically produce sounds above 18 kHz.

At normal volumes, a dog whistle is completely safe. Always start at low volume, keep signals short (under 5 seconds), and stop if your dog shows signs of discomfort (flattened ears, whining, trying to escape).

Frequencies between 15,000–20,000 Hz at moderate volume can deter approaching dogs. This is the principle behind commercial ultrasonic dog repellent devices.

Yes! The training presets follow professional standards: 3 short pips for recall, 1 long blast for sit/stop, 2 pips for turn. Consistency is key — always use the same signal for the same command.

Yes, it works in all modern browsers. However, phone speakers have limited high-frequency output (typically up to 16-18 kHz). For the best ultrasonic range, use external speakers or headphones pointed toward your dog (not worn).
