The PetSafe Bark Control collar is a highly effective collar at stopping annoying barking. This lightweight collar uses a vibration sensor to detect your dog’s barking, and 6 levels of Static Correction to discourage the unwanted behavior.
It is easy to use, with no external controls to configure. The stimulation level will automatically increase if your pet continues barking. The association between the offending action and the correction is learned quickly, and the unwanted barking will stop.
