Dream about the same dog is a metaphor for some instability and lack of control in your life. You are going nowhere in your work, relationship or other situation. You are experiencing a void in your life. It refers to a loss of faith, opportunity and trust. You are not being realistic.
The same dog dream is a signal for a growing problem or issue. You may be dealt with a lot of hard blows in your life. It is time to go back to a period where you can be more carefree. It is sadly a lost sense of spirituality. There is something in your life that you are not aware of or that has not yet surfaced.
If you dreamt about the same dog:
You pick up information quickly. Someone only needs to explain something to you once for you to grasp the concept. Your questions are concise. No one can accuse you of not paying attention to his or her words or actions. At the same time, you may be too sensitive to the information around you. An overload of stimuli could eventually overwhelm you.
