The SportDOG SBC6 bark control collar has 6 levels of automatic correction with a warning tone. When your dog is barking while wearing the barking collar, a vibration sensor detects the barking and emits a warning tone followed by the lowest level of static correction. If your dog does not stop barking after the first level of correction and starts barking again within 30 seconds, the barking collar will emit another warning tone followed by the second level of static correction. Each successive bark will increase the correction level if the bark is within 30 seconds of the previous bark in an attempt to stop persistent barking. If your dog stops barking for at least 30 seconds, the SportDOG SBC6 anti bark collar will reset back to the lowest level and the process starts all over again.
This anti bark collar also has a built in safety feature which will automatically shut off the anti bark collar for a period of 3 minutes if your dog barks 15 times or more in a 50 second period.
