The dog in the dream wants to treat you as a master and a slave. Of course, it means that you have to be a noble person recently (the closer the dream is to dawn, the shorter the time is) to help solve the problem.
In addition, according to the six divisions in The Wheel of Karma Life Law, there are four kinds of relationships with people: injustice (revenge), affection (gratitude), debt (repayment) and master (debt collection). A man looking for "Lord" will soon appear in your life, and you will get unexpected property.
"Dog" is a symbol of loyalty. If you have a loyal person to help you, you must be the "master" for him and consider his interests!
