How to choose the Best Ultrasonic Dog Repeller? Factors to Consider Before Buying

Dog repellent devices come with a variety of features. Therefore, choosing the right one that meets your needs and those of your pets is essential. So, here are some of the things to keep in mind when buying an ultrasonic dog repellent.

Frequency Levels

One of the features to consider is the frequency levels. The right repellent should have a frequency setting that is safe for dogs and humans.

You see, the average hearing frequency for humans ranges between 20HZ-20KHZ. However, a dog can hear a wider range from 15HZ-120KHZ.

Therefore, we recommend getting a device with at least 22KHZ for the best results. Also, you might want to consider choosing a repellant with different frequency waves for added convenience.


Most ultrasonic repellers come with different settings. Therefore, you must use the correct setting based on your pup’s behavior.

For instance, if you just want the device for controlling your dog’s barking, you should get one with higher settings.

However, to correct behavioral problems like chewing or digging, a device with low settings will be sufficient.


Another thing to consider is the working range of the anti-barking deterrent device. A good product should have a long range so you can repel the dogs from a safe distance.

Generally, a device with at least a 16.4ft range is good enough. However, some more premium units will have up to a 25ft working range. This makes it more ideal for outdoor use.


 Additionally, you need to consider if the repellant is portable. A portable unit should be light in weight and small enough to fit into your palm or pocket.

Also, you should get a device with a wrist strap to ensure it stays in place while walking around with it. The good news is that most of the units in this review are made with portability in mind.


Although optional, you might want to consider if the repellant you want to buy is weatherproof or waterproof.

A device that is weatherproof means it can withstand harsh elements like wind and other weather conditions. Waterproof units, on the other hand, can withstand ice, rain, and even snow.
