Most dog encounters don’t require physical contact if you can deter approach early. This electronic repeller emits ultrasonic frequencies that dogs find extremely unpleasant while remaining nearly inaudible to humans – effective deterrence without harm.
Who This Repeller Is Best For
- Mail carriers and delivery drivers entering unfamiliar properties daily
- Joggers and cyclists encountering loose dogs on their routes
- Dog walkers managing encounters with aggressive off-leash dogs
- Utility workers and service professionals entering residential areas
Is This the Right Dog Deterrent for You?
Choose this Electronic Repeller if you want:
- Humane deterrence without chemicals or contact
- 25-foot range to stop dogs before they reach you
- Dual-purpose training capability for your own pets
- Reusable device with replaceable battery
Consider something else if you need:
- Physical stopping power for attacks → Mace Canine Repellent Spray
- Bear deterrent capability → Bear Repellent Sprays
- Backup option for serious threats → Pepper-based Canine Spray
How It Works
The device emits ultrasonic frequencies between 35-45 kHz – well above human hearing range but precisely in the range that dogs find extremely uncomfortable. Point at an approaching dog and activate. Most dogs stop, back away, or change direction immediately. No contact needed, no chemicals deployed, no harm to the animal.
Practical for Daily Carry
At just 5.5 x 2.25 x 1.13 inches and 0.3 lbs, this device fits in a pocket, clips to a belt, or tucks into a mail bag. ABS plastic construction handles daily use. Standard 9V battery means replacement power is available at any convenience store.

Frequently Asked Questions
Does it work on all dogs?
Most dogs respond strongly to ultrasonic frequencies. Effectiveness may vary with individual dogs – deaf dogs or extremely aggressive dogs in attack mode may require backup deterrents like pepper spray.
Is it safe to use around my own pets?
Yes – the sound is unpleasant but not harmful. Many users actually use this device as a training aid for their own dogs. The effect is temporary discomfort, not lasting harm.
How long does the battery last?
Standard 9V battery provides many uses – exact duration depends on usage frequency. We recommend carrying a spare battery if you encounter dogs regularly throughout your day.
Will it stop an actively attacking dog?
Ultrasonic repellers work best for deterring approaching dogs before attack. For dogs already in attack mode, pepper-based canine repellent provides more immediate physical stopping power.
