If you dreamed about slaughtering a dog: The changes you will make can help you increase your self-confidence, then you can devote time to less important matters. Seeing a dog slaughter in a dream, although the slaughter is painful and not suitable for our faith, dog slaughter is a good sign. Since there is a dog around you who hides his true intentions and face, massacres are interpreted as disasters that will happen to these people. Even if you regret this situation, it will be for your benefit.
