    Buying Guide of Ultrasonic Dog Repeller

    Unless you haven’t owned a dog training/repelling tool in the past, the chances are that you aren’t familiar with the innovation. However, you don’t have to worry as in this section; we are going to cover all the basics related to the tool. So without further ado, let’s get started.   

    What’s A Dog Deterrent Tool?

    As the name suggests, a dog deterrent tool is used to discourage a dog from doing something negative like excessive barking, growling, and you name it. Pet owners and trainers use the device to train their dogs. That’s not it! This tool also scares away dogs and can be used when one is being approached by a potentially harmful dog.

    The majority of dog repelling/training devices make use of an ultrasonic sound that’s inaudible to human beings. This sound discourages the dog from abnormally barking, biting, etc. By using the sound, one can also train the dog to be obedient, loyal, obey specific commands, etc.

    Unlike a dog whistle, ultrasonic dog bark control devices are more effective as they directly produce sounds that mean something for the animal. And by frequently communicating using the tool, one can fully control their four-legged partner.    

    How To Use A Dog Barking Device?

    A dog barking device isn’t meant to replace traditional training. But with this device, one gets to closely and effectively communicate with dogs that are aggressive in nature.

    Generally, all dog repelling/training devices have similar controls. You’ll always find a button on the device that’s used to emit the ultrasonic sound for communicating with the dog. However, some equipment has more than one button that’s used to trigger other features. For instance, a product we have reviewed has two buttons, N & P, N is used to reward the pet, whereas P is used to slander bad habits.

    The majority of dog barking devices will include a manual that you can refer to for using it properly. You’ll be explained about every available feature and how you can use it practically with your pet. 

    Why Use A Dog Repelling Device?

    Here are some reasons why use a train/bark control device:

    Avoiding Danger

    Sometimes when you are outside, you can encounter dogs that are way too repulsive and harmful. You can’t outrun them, nor can you trust your luck to somehow get away. And that’s where a dog repeller can help you.

    Simply take out a handheld dog repeller from your pocket, aim it towards the dog and press the button for a few seconds. Ultrasonic sound waves released from the device will force the animal to flee.


    Bad habits can build over time if you don’t properly communicate with a dog and teach the basics. Dog owners and trainers worldwide make use of dog bark control devices to train their pets.

    By emitting ultrasonic sound from the device, you can break the destructive behaviors of your dog. Gradually use the device to connect with your pet. Give a treat on obeying commands and push the button when your cute puppy is doing something shady.

    What To Look When Buying A Dog Deterrent?

    There are some basic building blocks you must be aware of when buying a dog deterrent. Here are some things you must keep in mind when purchasing a new dog training tool:

    Types Of Deterrents

    There are two types of dog repellents available, handheld and stationary. Handheld tools can be taken anywhere; they are portable and meant to train or scare dogs on the go. Usually, these devices use rechargeable AAA or 9-V batteries. In contrast, stationary devices are intended to be installed at a fixed place. These devices make use of sensors to detect nearby animals.

    Note that stationery deterrents are only used to repel the animals. You can’t use them for training/teaching your dog. However, handheld tools can be either used as repellents, trainers, or both.

    Effective Range

    All dog training/repellents have an effective range. The majority of devices have up to 20 feet range. But stationary deterrents always offer more working distance than handheld devices. An advanced and premium handheld dog training can feature up to 30 feet range. In contrast, a stationary repellent can easily cover up to 50 feet.


    Most new stationary dog repellents run on solar, but they are also powered by a backup battery. Whenever solar energy runs out, the backup battery comes into action and helps the device to serve its purpose.

    Things are a little different with handheld dog training devices. They run on 9V or AAA batteries that can last up to 60 days of average use. Furthermore, some tools offer recharging capability, whereas others demand new batteries once old ones are dead.

    Additional Features

    Last and certainly not least, there are extra features that come with dog training tools. Some have variable/fixed frequency buttons, lights, while others feature different modes. Depending on your usage, pick a device that includes features that are your preference.

    For instance, if you like to walk or run outdoors at night, you must look for a dog repellent tool with LED lights. Not only you’ll be able to pinpoint the device correctly towards the harmful creature but analyze your environment for escaping if something goes wrong.

    Final Words  

    Even the friendliest dog can turn rogue sometimes, or the most obedient one can latch onto bad behaviors. So, whether you want to train your dog or keep yourself safe from the aggressive ones out on the block, a dog deterrent is the way forward. Use our buying guide to choose a dog training tool from the options we have reviewed.
