Safety Technology Electronic Dog Repeller and Trainer – Ultrasonic Handheld Device, Dual Mode 35-45kHz Frequency, 50-Foot Range, No Shock Technology, ABS Plastic, 9V Battery Included, 0.3 lbs

A Quiet Way to Create Distance

Encountering an unfamiliar or territorial dog while walking, jogging, or cycling is a common concern that most people handle by hoping it doesn’t escalate. This ultrasonic repeller offers a practical, non-confrontational option. It emits high-frequency sound that’s inaudible to humans but uncomfortable enough to make most dogs hesitate, back away, or redirect their attention.

It also doubles as a training reinforcement tool for your own pet — same technology, gentler frequency setting.

Who This Dog Repeller Is For

Walkers, joggers, cyclists, and delivery personnel who regularly encounter unleashed or territorial dogs. Postal workers and service technicians who enter unfamiliar properties. Dog owners looking for a humane training reinforcement tool that doesn’t rely on shock collars.

Also relevant for anyone who lives in an area where roaming dogs are common and wants an option that doesn’t involve sprays, physical contact, or confrontation.

How the Ultrasonic System Works

The device emits a high-frequency sound between 35-45 kHz — well above human hearing range but distinctly uncomfortable for dogs. When a dog hears it, the sound triggers an instinctive response that typically causes them to stop, back away, or lose focus on whatever they were approaching. The two-setting design lets you use gentler frequencies for training your own pet and stronger frequencies when deterring unfamiliar animals.

The 50-foot range gives you working distance before a dog gets too close. Point the device at the approaching animal and press the button. The sound is directional, so aiming matters. It’s not a guarantee — factors like age, hearing ability, breed temperament, and the dog’s level of arousal all affect how individual animals respond. But for the majority of curious or mildly territorial dogs, it’s been a practical option for people who need a non-invasive way to manage encounters.

Practical Details
