PetSafe Anti-bark collar for dogs Moy & GD

With six progressive levels, the PetSafe® stimulation collar teaches dogs to control unwanted barking. The dual-sensing system is triggered only when the sound of barking is combined with vocal cord vibration, ensuring optimum safety for the animal. The collar starts with the lowest stimulation level, then increases in intensity to the next higher level for every 30 seconds that the dog continues to bark, up to level 6. If the dog stops barking for at least 30 seconds, the collar resets and restarts at the lowest level. Each stimulation is accompanied by a warning tone. As a safety measure, the collar deactivates for 3 minutes if the dog barks 15 times or more within a 50-second period. For dogs over 3.6 kgAdjustable collar.
