The d-mute small lightelectronic bark collarsare a safe and effective way to help eliminate excessive or unreasonable barking from your dog. The electronic bark collar is a simple solution when your dog barks at the slightest stimulus, or even barks all day long when you are away, causing a nuisance to those around them.

The collar isactivated only by the vibrations of the vocal cordsof the dog wearing the collar, this system prevents the risk of false triggering caused by another dog barking. The sensitivity of the collar’s response to vibrations and the stimulation mode can be easily adjusted. The collar hasa total of five selectable modes forbark correction, you can choose between an acoustic signal, three levels of electrical stimulation and a stimulation mode with increasing intensity in five stages.

The d-mute device, in the form of a collar, helps teach a dog to remain silent. The dog must have the collar on the vocal cords so that the receiver can correctly evaluate its barking. The collar must also be tightened enough so that it cannot move on the dog’s neck, but it must not strangle the dog.It is activated automatically whenthe dog barks, howls or growls. The operating mode, i.e. sensitivity, correction method and time response can be easily set.Correction is understood as a sound signal or a correction impulse, or a combination of the two.

The electronic system of the collar uses modern technology based on a single-chip microprocessor. The collar is very easy to use, compact andwaterproof, therefore suitable for any situation.Thanks to its ergonomic design and low weight, it can also be used for small breeds of dogs.

Operating principle

In standby mode, the device waits for the dog to make a sound.At the first bark, it will emit a sound signal or a sound signal with a correction pulse, the intensity of which depends on the selected mode. If the dog continues to bark, the device will emit a sound signal or a sound signal with a correction pulse again.The collar will emit this sound signal or sound signal with a correction pulse a maximum of 5 times and then this process will stop automatically. After a longer pause from the dog (10-15 seconds), the system will switch back to standby mode, i.e. the next bark will be accompanied by a sound signal or a sound signal with a correction pulse.

Modes overview

1. only sound correction
2. sound + low level correction pulse
3. sound + medium level correction pulse
4. sound + high level correction pulse
5. sound + correction impulse in five increasing levels
6. function test
