How to do the best for your (mental sanity) family and your dog? 1. At the beginning, setting three training methods at the same time may make the dog overwhelmed and cause panic, so please set the beep mode only. 2. Set on a level 1 (least sensitive) within the house, dog is still able to let out a little woof and grumble without the collar going off; when outside, up it to a level 2 increase the sensitivity. 3.When the time comes you use power tools or the leaf blower, you can probably have to set it to a 5. 4.Once you know your dog has been retrained, you can put it back to the beep/vibrate mode.
