Electronic dog containment systems work without ever harming your pet. They´re designed to do nothing more than startle her when she triggers it.
Things to consider:
Get Enough Wire – Dog containment systems do not always include enough wire to cover the entire circumference of the area you plan to enclose. The wire does not always lay flat, and you will invariably need more than you think. You should buy more than enough, and you will save yourself a return trip to the online pet store.
No Harm –It is a common misconception that electric dog containment systems hurt the dog. This is a total fallacy. As long as the proper settings are used, it feels like nothing more than a static – just enough to scare or startle them without causing any harm. Don´t make the mistake of testing it on yourself. A dog´s neck and scruff are much thicker and hardier than ours, and their nerves are better protected.
Avoid the Shock – Most electric dog containment systems emit a beeping sound as a warning well before they have to give the dog a shock. If you train your dog to respond obediently to the sound of the beep, you can minimize and even prevent your dog from ever needing to be shocked.
