A police officer in Mississippi was making a routine safety check at a rest area , when he was attacked by three unknown men with boxcutter knives, for no apparent reason. The men slashed the officer with the knives and were dragging him off into the woods to finish killing him , when he was able to remotely release the K-9 police Dog from his car.
The dog then became the attacker, biting the three men, and allowing the officer to escape and radio for help in arresting the attackers.
These brave dogs are amazing, and well worth the time and effort that the trainers put into working with their K-9 helpers.
The dog was reported to be covered in blood after the incident; so probably he was also being slashed with the knives as he valiantly saved his partners life !
