Buyer's Guide

Using an Ultrasonic Dog Repeller

Dog repellent is not intended to replace traditional training, and this must be understood immediately. This is a common tool for obstinate and unruly dogs that love lengthy discussions with neighbors 10 miles away.

Using a dog deterrent sound may be a viable choice if traditional training has failed to stop your dog from persistently barking, digging, or chewing up furniture and other possessions.

Additionally, if there are vicious or violent mutts in your neighborhood, this is a smart strategy to defend oneself.

Let’s see how to employ one of these portable options:


Many of these and other devices have distinct configurations. You must ensure that you are using the proper setting. Low settings should only be used for digging, eating, and other orders.

Higher settings are intended for situations in which your dog is barking (they will be able to hear the sounds over their own racket) or violent dogs are approaching you.

In high-stress situations, you may also utilize the device’s LED light in conjunction with the loud volume.


It is normal for a dog repellent to have a range of around 20 feet. During basic chewing, digging, and barking training, however, you should be within six feet of your dog.

Hold the gadget immediately in front of you with the extended arm aiming directly at your pet.


When utilizing this gadget as a training aid, you must ensure that the ultrasonic sound is sandwiched between orders.

For instance, use: quiet / press the button / quiet to ensure that your dog comprehends the instruction and will do so in the future. Remember that you should also provide positive praise when your dog performs appropriately.

As previously stated, these tools are not intended for casual usage and should never be utilized when your dog is behaving well.

The sound is irritating and demeaning to them, much like fingernails on a blackboard to humans, therefore be very cautious not to activate the sound until necessary.

Shopping Advice

As you can see from our evaluations, there are two types of ultrasonic dog repellents available for purchase. One is a portable model, while the other is a fixed one that may be installed in your yard.

Both are viable solutions with distinct characteristics, depending on your requirements. First, let’s consider the portable alternative.

Handheld Dog Repellers

If you like lengthy walks, running, riding, or any other activity that will take you away from home with your pet, a portable alternative is ideal. Obviously, this is also beneficial if you have a fear of other dogs in your neighborhood.

The dog deterrent will come in help if your dog is a strong puller, likes to bark at other dogs, or dislikes other dogs that they may try to attack.

When searching for one of these possibilities, you should go for one that is robust and equipped with several functions. If you enjoy nighttime strolls, LED lights are also a viable alternative.

Static Dog Repellent

If your dog spends a lot of time outdoors and has a large number of companions, a stationary alternative is ideal. They are also a viable alternative if you have a neighbor with a dog that barks constantly throughout the night and day.

When searching for one of these solutions, you must ensure that it is robust and waterproof. Solar electricity is also beneficial, although it is not always essential.

The challenge with these units is locating one that will be effective in the space you require. If your dog is running in a 30-square-foot yard and you only have a 10-foot propeller, it will not be sufficient.

Additionally, you must ensure that it will not bother your dog while they are exhibiting their finest behavior. Choose an ultrasonic deterrent that will not activate every time a door closes or a squirrel chirps.
