Keep Dogs at a Distance.

With the push of a button, OnGuard™ repels dogs up to 15 meters away using a stream of ultrasonic sound. This high-pitched sound is inaudible to you, but has a strong repelling effect on approaching dogs.

Become the Center of Attention.

Quickly draw attention to your location by activating the loud, pulsating panic alarm. The audible alarm can be turned on (and stay on) if needed in an emergency situation.

Light Up the Dark.

Illuminate dark parking lots, paths, and rooms with the OnGuard's high output LED flashlight. Use the flashlight in constant mode or switch to the strobe option if necessary.

Easy to Carry. Comfortable to Hold.

The ergonomic hand grip and dual rubber coating make taking OnGuard™ on your next neighbourhood stroll or 5K run a breeze.

Listen Up, Fido.

Use OnGuard's ultrasonic function to deter your dog from unwanted behaviors like barking or jumping on the furniture. This technique helps stop bad habits all while being completely safe and humane.

Frequently Asked Questions

What is ultrasonic sound?

Ultrasonic sound frequencies are above the hearing range of humans. Although this noise is inaudible to most humans, dogs hear it loud and clear. This high-pitched noise is alarming and unpleasant to dog being targeted, but completely safe and humane.


Will OnGuard™ work on dogs in other rooms or on the other side of a fence?

Ultrasonic sound cannot travel through solid objects like walls or solid fences. Make sure OnGuard™ is in clear line of sight of the dog you wish to train or deter.


Will this protect me from an attacking dog?

Dogs can be unpredictable and while it is designed to repel them, we cannot guarantee it will deter an overly aggressive dog.


Will this hurt the dog?

No. Although the ultrasonic sound emitted by OnGuard™ is a great tool for repelling and training, it is physically harmless to dogs.


Can I use this to train my puppy?

Due to the powerful nature of this product, it is not recommended for use on puppies under 6 months old as they are still developing their hearing.


What’s the blue light on top for?

The blue LED light on top of the unit indicates the ultrasonic button has been pressed and ultrasonic sound is being emitted.


What is the range?

The ultrasonic frequencies can be heard by dogs up to 45 meters away (for training purposes), and can repel dogs up to 15 meters away.
