The Dogtrace d-mute small anti-bark collar, thanks to its very small receiver and truly small correction impulses, which can be set in five modes and one test, is suitable only for small dog breeds (6–15 kg). The D-mute small anti-bark collar prevents barking using an audible warning, a correction impulse, or a combination of both. Function modes are changed simply by applying a magnet. The collar is activated only by vocal cord vibrations and triggers automatically when barking, howling or growling. Sensitivity can be set in three levels and is adjusted inside the collar. Dogtrace d-mute small is supplied with a fully waterproof and submersible receiver, making it suitable for both home and outdoor use. You can use it in rain or snow and the dog can submerge in water with it. It runs on a replaceable 3V lithium battery labelled CR2 and lasts in operation for around 6–12 months.

Bark detection
Dogtrace d-mute small light responds to vocal cord vibrations, so the collar cannot be triggered by another dog moving nearby. The collar activates when the dog barks, howls or growls.
Correction type
The device uses an audible warning and an electrostatic impulse as correction.
Collar settings
D-Mute small light allows you to set 5 different modes for bark correction. Set tone only, impulse at levels 1–3, or choose the option with a gradually increasing impulse. Dogtrace d-mute light also features bark sensitivity detection and is therefore suitable for correcting howling as well. You control all functions very easily by applying the supplied magnet.
