Static Shock Remote Training Collars deter barking by emitting a safe static shock at the time of your choosing. Unlike automatic training collars, you as the owner are in control of 'when' and the level of shock. This style of manual training works very well if you are training out an issue that is not as repetitive (barking at certain things rather than everything) or to discourage rough play at the dog park, biting, fence jumping etc.
