A dog is always a danger. Stray animals often attack people. And even training is not a guarantee of constant stable behavior of the dog. But there is a solution: the ultrasonic dog repeller is small enough to fit in a woman’s purse or pocket, it can be bought for children. The device against dogs is quite effective. And many models have a complex deterrent effect.
What is an ultrasonic dog repeller
Using a dog repeller is quite simple. The device is directed to an aggressively behaving animal. When the trigger is pressed, the compact repeller performs several annoying and even painful actions for the dog at once.
The main factor by which a stationary or pocket electronic dog repeller operates is the sound, or rather, high-frequency vibrations. They are above the 20,000 Hz mark, within which the human ear operates. People simply do not hear the sound emitted by the device. But ultrasound acts literally overwhelmingly on dogs. First, it is a sharp discomfort. Secondly, the animal has strong negative feelings. The fact is that even at a sound pressure level of 100 dB, the pain threshold is reached.
Important! In humans, this figure is 130 dB of audible frequencies. Therefore, sensitive people, using a sufficiently powerful ultrasonic emitter, may experience some discomfort. Such individuals are advised to choose a device with a directional waveform.
The main suppressing factor is supplemented by:
- intense flashes of light;
- abrupt changes in sound level to achieve maximum impact.
A device that combines sound with other influences is not only effective, but convenient enough for other uses.
Characteristics for choosing an ultrasonic repeller
It should be understood that any dog repeller works on the same principle. And most importantly — choose a device with the optimal ratio of directivity, range, body size for easy portability.
The range of the device depends on several factors.
- Dogs are afraid of sound pressure levels. Therefore, the power characteristic of the emitter should be at or above 100 dB.
- The range of the device determines the safety zone for the owner of the repeller. When attacking in open space, a dozen meters is enough to maneuver. Device with 20 meters or more able not only to keep the attacking animal at a distance, but also to work through the wall.
- Radiation Directivity. As mentioned above, a strong sound stream, even with a frequency that is inaudible to the ear, can cause discomfort in sensitive people. A repeller with a directional emitter is suitable for them. However, such a device has a key drawback: with its help it will not be possible to keep a whole pack of dogs at a distance. You have to aim directly at the one that carries out the attack.
There are many technical solutions on the market today. Devices in the flashlight format, such as the Wasp, are directional and work at a distance of up to 15 meters. More powerful solutions «take» up to 20.
The presence of additional factors of influence
Additional scare factors include a strobe light to produce sharp, bright flashes of light that affect the animal’s eyes, as well as spark gaps for a sharp, frightening sound. They make the device much more efficient. However, it is worth remembering that each additional option not only increases the cost of the solution, but also serves as a factor charge consumption of power supplies.
Batteries or accumulators
Rechargeable battery as a power source for the repeller — technically better than batteries. It has a large capacity, in the mode of issuing high currents it works more stable. However, at low air temperatures, the advantages of the battery fall. It cannot deliver significant current.
However, batteries are more stable. They serve less, they have to be changed, not recharged. That is, each time to buy anew. Therefore, it is worth choosing a power source according to ease of use.
Advice! In regions without severe frosts, a battery-powered repeller equipped with a charge indicator will be much more functional and more convenient than a battery-powered solution.
Quality and materials
The assembly of the case, its strength are of great importance. Yes, a homemade dog repeller can be just as effective as the best retail model available. But a durable case ensures that the device remains operational after falls. Water Repeller can be used even during showers. And convenient switches and the start button guarantee fast application.
You should not buy a frankly cheap device in a plastic case. The device must be solid, without backlash and slots, with reliable switches and a convenient start system. It is worth paying attention to burrs, the quality of the coating, the stability of button presses, the strength of fasteners, for example, a lace for hanging on the arm.
How to use the device
Most dog repellers follow the same pattern. The device is aimed at the attacking animal, after pressing the button, sound is emitted and bright light flashes are issued. This is how pocket solutions in the flashlight format work. They have a pronounced directional action and are most effective for dealing with one animal.
Devices without a bell of the portable type are usually hang on hand. They also head for one of the attacking animals. This helps to scare off the most aggressive dog. At the same time, the device emits sound in a wide front, which allows you to drive away the rest of the attacking flock. This solution is optimal for urban conditions, when animals surround from all sides on fairly narrow streets where there is no room for maneuver.
Important! The effectiveness of portable options increase the characteristics of the propagation of ultrasound. It is able to bounce off obstacles without a significant loss of power, to interfere, enhancing the action. Therefore, in a confined space, a device without a pronounced directionality will be very good against an attacking flock.
Ouse whistle for training
An uz whistle is easy enough to make with your own hands. For example, by disassembling the insect repeller and placing its functional parts in a more convenient case. The power of such an ultrasonic emitter is small. It does not have a painful, shock effect on dogs. And maybe be used in training like a normal sound signal with one important difference: it does not disturb others. A home-made whistle or a whistle bought in an ultrasound store is completely inaudible to people.
Is it worth buying a stun gun for dogs
There are two types of such repellent and restrictive devices. It:
- dog stun gun, attack protection device;
- stun collar for dogs, used as a training tool or a means of restricting movement.
The last class of devices is clear and simple. The electric collar can deliver small current pulses at the signal of the remote control. They do not harm the dog, delivering only minor discomfort. It’s great trainer’s tool. At the same time, such a collar can be used to control the movement area of the animal. When the specified distance from the beacon is exceeded, the device starts to shock the dog. The impact is stronger the farther the animal goes.
A dog stun gun has the same principle of operation as a device for stopping aggressive human attackers. The device generates high voltage pulses. When in direct contact with the skin or coat of a dog, it receives paralyzing or sharply painful blow. Modern stun guns work in a complex way.
- Before contact with an animal, sparks are formed in the visible area of the device. They emit a sound wave in a wide range of frequencies, causing discomfort to the dog’s hearing organs.
- The built-in strobe emits intense flashes of light.
- When an attack begins, the animal can be stopped by direct contact.
The disadvantage of the stun gun from dogs is obvious: it does not have a pronounced significant range. In addition, the use of such a device requires skill. After all, in order to stop the attacking dog, you need to correctly provoke it to the point of attack, dodge and still kiss with a shocker.
Therefore, it is not recommended for ordinary people to buy this device. This cannot be justified even by thinking that a dog device can stop, so to speak, two-legged attackers. Modern shockers for people have not only higher power, but are also equipped with blocks of ultrasonic repellers.
