In our culture the dog is the guard of the home. It is usually tied by the entrance of the house so that an intruder couldn’t freely enter. Usually the dog would bark to want to home owner. If the dog is not a barker then it would be kept in the backyard.
We also have dogs but they are all barkers. When someone would ring the door bell expect pandemonium in our living room. The cacophony of barks from the 3 dogs would be like a concert of cymbals and drums. At least we still have a guard dog, I mean guard dogs.
Do you see a guard dog in your neighborhood?
