d-mute electronic bark collars are a safe and effective way to help eliminate excessive or unreasonable barking from your dog. An 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, disturbing those around them.

There are four models available to suit different dog sizes. The d-mute and d-mute light models are designed for medium and large dog breeds, while the d-mute small and d-mute small light models are suitable for medium and small dog breeds.

The collar is activated only by the vibrations of the vocal cords of the dog wearing the collar, this system prevents the risk of false triggering caused by the barking of another dog. The sensitivity of the collar's response to vibrations and the stimulation mode can be easily adjusted. The collar has a total of five selectable modes for barking 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 receiver and 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 tight enough so that it cannot move on the dog's neck, but it must not strangle the dog. It is activated automatically when the 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 pulse, 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 and waterproof, so it is suitable for any situation. Thanks to its ergonomic design and low weight, it can also be used for small dog breeds.

Operating principle:

In standby mode, the device waits for the dog to make a sound. At the first barking, 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 . This sound signal or sound signal with a correction pulse will be emitted by the collar 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 barking will be accompanied by a sound signal or a sound signal with a correction pulse.

Overview of modes (individual modes are changed by simply holding the magnet near the collar):

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