I was in a village in Costa Rica and was allowed to pet a mix dog that was said to be vicious well both dogs. I was able to walk the mix dog and was pretty aggressive to other dogs. However, the German shepherd was not able to pet say hi or anything. You see both dogs are used as tools only to protect property. Anyways as I was sitting down petting the mix dog the GS was quiet relaxed sitting down. Then got up and starting barking even lunged. I swear the dog was saying "Watch out you idiot look behind you or your going to die!" I was like what are you barking at and even tried to break free. Then got quiet. I turned around and a jeep nearly hit me like 5 inches from hitting me in the back. I was so lucky. I thought to myself I think this Geman shepherd that has a bad name by everybody in the village tried to save my life.
