Extreme Dog Ultrasonic Dog Repeller
Anti barking device and ultrasonic dog repeller.
It has 2 functions that work independently. If you use the ultrasound, the sound does not work, and vice versa.
UltrasoundUltrasound: uses a frequency of 22 – 25 KHZ, which is imperceptible to the human ear to perceive, but it is the most sensitive frequency for dogs.
There are 3 ultrasound powers:
1) Stable and continuous frequencies.
2) Undulating frequencies.
3) Frequencies with irregular intervals.
It is recommended to use all frequencies of the ultrasonic dog repeller so that the dog is baffled.
Let’s remember that ultrasound is a mechanical vibration with a frequency higher than those that can be perceived by the human ear, but dogs do perceive it and this ‘noise’ is annoying for the developed ear of dogs.
SoundIt is perceptible to humans and annoying to the dog (no, it will not adversely affect the dog’s hearing or health). It is a beep similar to an alarm and is very annoying for dogs.
The dog repeller is handheld size and easy to use: it fits perfectly in your hand and comes with an anti-static wrist strap so you can easily carry the device while walking your dog.
USB rechargeable: unlike other battery-powered devices. Built-in 300 mA battery can be powered by computer, power bank, USB adapter etc.
The red light will flash when less than 15% power.
It is also valid for training and bark control, since dogs associate ultrasound with a negative stimulus.
