The SportDOG Bark Control collar is lightweight, but highly effective. The adjustable collar is the easiest to use bark collar on the market. When a dog barks wearing the bark collar, a vibration sensor detects the bark and emits a warning tone followed by the lowest level of correction. If the dog is not deterred by the first level of correction and starts barking again within 30 seconds, the bark collar will emit another warning tone followed by the second level of correction. This correction will continue until the dog stops barking. This bark collar has a safety feature built-in which will automatically shut-off for a period of 3 minutes if dog barks more than 15 times in a minute.
