It is a very small and light anti-bark, and with batteries it weighs only 50 grams, so it can be used in dogs from 4 kg.
When the dog barks, the collar detects the vibrations of the vocal cords. This way the collar will never pop out due to the barking of other dogs.
Before punishing the dog, it always warns you first with a beep. This allows the dog to quickly learn to stop barking as soon as it hears the warning sound.
In case of not keeping silent after the audible warning, the collar will emit a progressive impulse, starting at a very low level to avoid hurting the animal's sensitivity.
This progressive regulation makes the Bark Control anti-bark collar adaptable to all types of dogs, from the most sensitive to the most stubborn.
