While electric fences can deliver a significant shock, they are generally not considered harmful to animals. The electric current used in these fences is typically low-amperage and high-voltage, causing a brief, uncomfortable sensation rather than causing any lasting damage.
Livestock can quickly learn to respect an electric fence and will usually avoid contact once they have experienced the initial shock. Proper installation and regular maintenance of electric fences can minimize the likelihood of injury and ensure the well-being of animals.
