Most dogs alert you whenever a person arrives at your doorstep, but it takes a special type of dog to spot the difference between a harmless visitor and an intruder. Moreover, certain breeds of dog are more capable of thwarting or disabling an intruder than other breeds. These dogs are generally larger in stature and stronger than other breeds. Therefore, they must be highly trained and socialized to harness those attributes while keeping them under control.
