People who have been bitten by angry dogs suffer from obsessive phobia all their lives. The fear of homeless animals not only makes it difficult to move around the city calmly, but also makes you worry about the safety of your own children. Sometimes you need to scare away a pack of stray dogs to get to a school or store. A stick or a stone against a whole pack is a failure, especially if a child has to defend himself.

How to scare away dogs

The use of special dog repellents (dizers) is a real chance to protect yourself and your loved ones. These devices easily fit into the pocket of a jacket, backpack or women's handbag, and just as quickly remove from there when necessary. It is important to understand the principles of operation of different dizers in order to choose the most powerful one. Among those on the market, the most effective is an ultrasonic repeller.. His action is enough for 13 m, which means that the dogs will not have time to come close.

The cost of factory divers is quite high, so people often use homemade devices. Real craftsmen will be able to make any scarer with their own hands: chemical, ultrasonic or electric. Why buy an expensive device if your own option is no less effective?

Do-it-yourself chemical dog repeller: what and how to make

Do-it-yourself mole scarer

Chemical dizers are devices filled with a composition that is toxic to animals and humans. The principle of action of the repeller is to spray a caustic liquid on the mucous membranes of the eyes, nose, and mouth of the dog. It is difficult to assess the effectiveness of such a diser. Firstly, its use involves close contact with angry animals, which in itself is very dangerous. Secondly, when a large number of dogs attack, there is simply not enough time to spray a can of "chemistry" on everyone.

Note! It's easy to make a chemical repeller. The work will need components that can be found in any kitchen: ground black pepper, vinegar, mustard powder. Some people use makhorka instead of vinegar when making such a diser. As a result, cans with different compositions are obtained.

How is a chemical diser made at home?

Option number 1:

  1. Preparation of a container for a chemical composition. Typically, this is a 0.5 liter plastic bottle without a cap, on which the sprayer is put on.
  2. Kneading the composition: pepper is added to the vinegar, everything is shaken together.
  3. The liquid is poured into a bottle, tightly closed. Not very convenient, but you need to carry it with you.

Option number 2:

  1. Preparing a container for a chemical mixture. It is convenient if it is a 0.25 liter jar with a tightly screwed lid.
  2. Preparation of a caustic mixture: finely chop the shag, add pepper and mustard powder. Mix.
  3. Transfer everything to a jar and close the lid. Carry with you, when attacking an aggressive dog, pour the contents onto the animal.

Do-it-yourself ultrasonic dog repeller: circuit, powerful dizer

The ultrasonic dispenser, which makes a sound unpleasant to the dog's ear, is highly efficient. The advantages of this device are that it is absolutely harmless to people and works even over long distances.Stray dogs immediately pay attention to the ultrasound signal, rapidly leaving the place of meeting with a person. Using the device in a critical situation, it will be possible to immediately disperse the whole flock, and not fight off each dog separately.

Dog repeller scheme

You can make an ultrasonic dog repeller with your own hands according to different schemes of powerful dizers taken from the Internet. They can be altered if technical skills permit, or used off-the-shelf. The universal circuit of an ultrasonic dog repeller assumes the presence of a microcircuit, transistors, resistors, diodes. At the stage of assembling the device for scaring away with ultrasound, it is important to follow the recommendations of specialists:

  • use a piezoceramic emitter during the manufacture of the diaser, which will evenly distribute the load;
  • select LEDs D3 to turn on the light. They are installed in the farthest part of the device;
  • in order for the repeller to work at a frequency of 25 kHz, you need to take the P35 resistor, but you should not experiment with the frequency parameters. In this regard, it is better to stick to the factory model settings;
  • the power of the ultrasonic sizer should not exceed 130 dB. Otherwise, the device will not only scare away the animal, but also cause significant harm to it;
  • for long-term operation of the ultrasonic device, it should be equipped with slots for 8 9V batteries;
  • checking ultrasound pulses is the final touch in the work. It can be carried out using an oscilloscope or sound card compatible with a computer;
  • if the device was prepared for stationary use (for example, for a summer residence), then it must be enclosed in a moisture-resistant case and provided with clamps.

Electric dog repeller: accessories and assembly rules

Due to ignorance of the principles of operation of an electric dizer, it is often confused with a conventional stun gun. Many people immediately refuse to buy such a repeller, since this contradicts their ideas about a humane attitude towards animals.

Important! The electrodiser is not intended to be in close contact with the dog's body. The device only creates a loud intermittent noise effect that scares off aggressive animals.

To make an electric dog repeller at home, you will need the following elements: a plastic bottle, a high-voltage module, a micro-button and a finger battery. The technology for creating a homemade device is simple:

  1. Fasten the finger battery and the module with electrical tape.
  2. Solder the button and wires to the battery surface.
  3. After making the base for the repeller, cut the electrical wires.
  4. Cut off the neck from the plastic bottle, obtaining a diffuser to enhance the sound signal and protect against voltage.
  5. Place the diffuser on the electrical module, making small notches on the neck.
  6. Well glue the junction of the neck and the module.

Visual information on how to make an electric dog repeller can be obtained from videos on YouTube, which are filmed by people with special technical skills. In the same place, the electricizer is shown in action: the sudden crackle of electrical discharges depressing the dogs, and they hide. No matter how many stray animals are to be faced, loud discharges of the electric scarer will make everyone scatter.

Note! Despite the tolerance of most people towards stray animals, it is unacceptable to be careless about your own safety. A dog is truly a friend of man, but only if it is cared for from puppyhood and kept in decent conditions.

Stray dogs live according to different laws, and it is difficult to predict their behavior in a given situation. Because of the trials that street animals have to endure every day, they become embittered and increasingly rush at passers-by.

A homemade dog repeller will always protect a person, the main thing is to keep the device with you.No one knows where a dangerous skirmish with the pack will happen: during an evening walk, in an unfamiliar area, on the way to the house. Homeless dogs can share prey, territory or chase a bitch; you should not specifically attract attention to yourself and try to calm the animals down. Task number 1 in this situation is to leave the dangerous territory as soon as possible, but if it did not work out, use the repeller.
