Can Guard Dogs Help Keep You Safe From An Intruder?

When the masked man walked to Nancy Guthrie's doorway, apparently no one heard anything. A guard dog may have changed that. In a demonstration done for Inside Edition, Everest the dog went bananas when a man played an intruder. Everest is Jane Dorian's dog. She lives in Beverly Hills and says her German shepherd makes her feel safe. Mike Israeli owns Delta K-9 Academy and trains Everest. There has also been a surge in the purchase of home security cameras.
