I recently read a story about a family that had an all too common problem with their dog—it wouldn’t stay in the yard. Rather than chain Fido to a tree, they opted for the modern high-tech solution and installed an invisible fence. A wire was buried in the yard and an electronic collar was placed around the dog’s neck. If the pooch got too close to the wire a warning tone went off. If he got way too close he received a light but effective shock.

The Shocking Reality

It didn’t take long for the dog to discover his limitations. Even with the promise of treats, he would not dare cross the line. He couldn’t see the barrier, but it was all too real for him. He had been trained to know exactly where he couldn’t go.
