Frequently Asked Questions

Q: How does the ultrasonic dog repeller work?

A: The ultrasonic dog repeller emits high-frequency sound waves that are within the hearing range of dogs but completely inaudible to humans. When pointed at an approaching or aggressive dog and activated for 2–3 seconds, the discomforting frequency encourages the animal to back away — humanely and without physical contact or chemicals.

Q: Is the ultrasonic sound harmful to dogs?

A: No. The ultrasonic frequency used is designed to be unpleasant and attention-grabbing for dogs, not physically harmful. It disrupts their focus and deters aggression or nuisance barking without causing injury. It is a widely accepted humane deterrent method.

Q: How long does the battery last and how do I charge it?

A: The built-in 3.7V 350mAh lithium battery provides 5–10 days of normal usage and up to 30 days on standby. Charging is simple — just connect the included USB cable to any USB power source and the device is fully charged in approximately 2 hours. The LED indicator will notify you when the battery is low.

Q: Can this device be used for dog training as well as repelling?

A: Yes! This versatile device functions both as a dog repeller for self-protection outdoors and as a dog training aid. The ultrasonic pulse can be used to interrupt unwanted behaviours such as excessive barking, jumping, or aggression, making it a useful tool for pet owners looking to reinforce training commands humanely.

Q: What is the effective range of the ultrasonic dog repeller?

A: The effective control distance is 5–10 metres (approximately 16–33 feet), making it suitable for most real-world outdoor encounters with dogs while walking, jogging, or cycling.
