Shopping guide

Dog repellents are practical devices to prevent dogs or other animals from wandering around the home and causing damage or getting in front of the car. The options for these devices are extensive and vary by ultrasound frequency, design, and more. For this reason, we have prepared a guide to buy the best dog repeller. 

type and design

It is necessary to establish a comparison of dog repellents in which the types of devices or the mode of use are differentiated. This is recommended because there are alternatives on the market designed for different purposes. 

For this reason, we can find dog repellents for the car, which are installed on the bumper or grill of the vehicle, in order to emit ultrasonic frequencies that will prevent wild animals from jumping onto the road while the car is traveling. In this way, accidents are reduced. 

Another type of repellers are the fixed ones for gardens (or any other space where they want to be placed). These objects, like the previous ones, also work with ultrasonic frequencies and some are equipped with a flash. They are models with adjustable sound frequencies and large dimensions. The intention is that they be placed in the gardens, with a view towards the place where wild animals come from, be they dogs, cats, raccoons and other members of the fauna.

Also, there are personal repellents, which are portable, compact and pocket. In this modality two types are differentiated, the electronic ones (they work with batteries) and the manual ones (generally, whistles). They are designed to be efficient in different situations, since, in addition to scaring away, they can be convenient elements when it comes to training pets, because with the ultrasonic frequency they can be taught different commands. In general, the intensity can be adjusted according to the size of the animal and its use is simple.


If you are interested in purchasing one of these devices, you may also be interested in knowing how much a dog repeller costs. The answer to this question may vary according to factors such as type and construction. 

In the case of the type, those for installation in gardens tend to be more expensive. Regarding the construction, almost all models have been manufactured with a thick plastic or ABS casing that covers the mechanical components, so they are resistant. As for the whistles, they tend to be made of metal, so they are cheap, since they have simple structures and are usually made of brass. 

The most expensive models are those for the home, since they are equipped with modes for the frequency, they are larger and many of them are waterproof, so they have IP66, IP44 protection, among others. In addition, it is possible to adjust the frequency in modes, according to the animals that you want to keep away.  


A cheap dog repellent is a proposal that should be analyzed before buying, because, although the price may be attractive, its efficiency may not be so. For this reason, before making the purchase, it is advisable to know the operating mode or mechanism used to keep animals away, since, in addition to fulfilling its mission, it is important that it does not harm the creatures. 

The vast majority of models base their mechanism on ultrasonic frequency waves, which may not be heard by the human ear, but can be heard by dogs and other animals. In addition, some devices can incorporate a flash, which is activated when movement is perceived. Also, it is common for the frequency tones to be adjustable, between high and low. 

Range and frequency 

Depending on the model, its range and frequency may change. In the case of car models, they can extend their frequency up to 400 meters in the forward direction. In the whistles, it is possible to regulate the intensity by means of a nut, while the electronic models have a setting for small, medium and large domestic dogs. 

On the other hand, designs for the home have frequencies encompassed in modes, which are adjusted to different requirements. For example, mode 1 can go from 13.5 kHz to 17.5 kHz and mode 3 from 19.5 kHz to 23.5 kHz.

Also, some models have a maximum detection range of 10 meters, with an infrared detection range that can go from 90 to 110º for coverage areas of between 85 or 100 m 2 and even more. 

Frequently asked questions

Q1: How to use a dog repeller?

The way of using these devices changes according to the type of model that has been purchased. In whistles, it should only be brought to the lips and blown near the animal to certify if it has been effective. Otherwise, it is possible to regulate its intensity and frequency by means of a nut. 

In the electronic models, its use is simple: you must insert the batteries, turn it on and select a mode (usually by means of buttons) according to the size of the animal, so that the frequency and sound pressure start. 

In home models, it is generally necessary to select the place to install the panel (many work with solar panels) and the device to repel in the direction where the animals come. Afterwards, it is only necessary to turn on and set the mode for ultrasonic frequency. 

Q2: Is the dog repeller harmful?

Most are not. These devices are efficient at scaring animals away without causing them any harm, so they are a prevention mechanism that does not hurt them, it only generates waves of ultrasonic frequencies that can momentarily disturb their hearing (in some cases) and will make them move away, but there will be no permanent damage. 

Q3: How to make a homemade electric dog repeller?

To make this equipment it is necessary to acquire two pieces of wood, a speaker, a battery, screws and some connections, as well as a transistor to amplify the signal. First, the base must be made with the wood (one of them must have a hole in the center) and they will be joined using connectors and screws.

Then, you have to place the speaker in the hole. For electrical operation, find a diagram to assemble and add a switch as well as a battery. If you want to verify that the diagram is adequate, you must do a resistance test and that the result is at least 24 kz. Thus, it will be ready to be used.

Q4: What radius of action does a dog repeller have?

This depends on the type that has been selected. Some car models have a radius of action of up to 400 meters to the front. Others have a certain level of action and detection, so they are capable of perceiving movements at angles of 70 or 80º, with infrared detection of 7 or 9 meters and a coverage that can go from 70 to 120 m 2, according to the model that has been selected.

On handheld devices, they can have a radius of up to 25 meters. These parameters are usually indicated in the specifications of the device.

Q5: How to install an outdoor dog repeller?

The first thing will be to select the place where the device will be installed. Many of these models work with multiple charging systems and integrate solar panels and auxiliary charging ports for batteries. Therefore, if the equipment has a panel, it is necessary to install it in a place where it receives sufficient sunlight.

In addition, the device will need to be placed facing the area where wildlife is most frequently coming from to be most effective. Similarly, it is necessary to protect the cargo area from rain, since, although the equipment may be water resistant, it is recommended to avoid contact of the liquid with the mechanism. 

Q6: How to repair my dog ​​repeller?

Repairing a dog repeller is a process that changes according to the model and operating mechanism. In electrical models or mechanical operation that results from the power of a battery, it is best to check the contact to certify that it is generated properly. Also, in models that have solar panels, it is recommended to verify that they receive enough sun.

In any case, if the equipment has been purchased for a short time, you should avoid opening and contacting the seller of the product to use the guarantee.

Q7: What frequency does an ultrasonic dog repeller have?

The ultrasonic frequency varies according to the brand and model that is selected. Some personal electronic devices have a frequency of up to 25 kHz for a sound pressure of 125 decibels.

Other models for installation in gardens have adjustable frequencies that start from 13.5 kHz and can have a maximum of 28 kHz. Similarly, there are models that advertise frequency ranges from 18 to 24,000 Hz, with estimated sound pressures of 110 decibels.
