This is the latest version dog training shock collar!

The product is voice-activated. At the 1st bark the product applies a short warning tone. If a 2nd bark occurs within 30 seconds a more intense tone is sounded along with a short mild shock. If your dog barks a 3rd time, both the tone and shock become more intense. This pattern is repeated through 6 correction levels. If your dog continues to bark through all 6 levels, the most intense sound and shock are applied after each bark until your dog stops for 30 seconds or more. After 30 seconds of quiet, the product automatically resets to the 1st tone only level of correction. When your dog forgets and bark again, the warning tone reminds your dog without immediately applying painful stimulus

You can adjust the sensitivity of the item, high or low if you want, in order to find the voice of your pet wuth the exact scope,thus will not punish your dog for the other voices of restless
