Frequently Asked Questions
Q: How does the ultrasonic dog repeller work?
A: The device emits high-frequency ultrasonic sound waves within the 5–10 metre range. These frequencies are detectable by dogs but inaudible to humans. When pointed at an approaching dog and activated for 2–3 seconds, the ultrasonic signal startles and deters the dog without causing harm — making it a humane and effective deterrent.
Q: How long does the battery last on a single charge?
A: The built-in 350 mAh lithium battery provides 5–10 days of active use and up to 30 days of standby time. A full recharge takes approximately 2 hours via the included USB cable, making it quick and convenient to keep the device ready.
Q: Can I use this device to train my own dog?
A: Yes! In addition to deterring unfamiliar dogs, this device can be used as a training aid for your own dog. The ultrasonic signal can help interrupt unwanted behaviors and reinforce commands during training sessions when used consistently and with positive reinforcement techniques.
Q: Is the ultrasonic sound harmful to dogs or other pets?
A: No. The ultrasonic frequency used is designed to be startling and attention-grabbing, not harmful. It is a widely used humane approach to dog behavior management. Always use the device responsibly and avoid prolonged, close-range exposure to any animal.
