The dog house is a symbol of isolation and punishment. It is the place where you are put when you do something wrong and it is the place that you are left in when you have done something wrong. Take some time to self reflect on what you did wrong.
This symbolism of the dog house can be seen in many different ways, such as being punished for your actions or being put into a situation where you feel like nobody can help you. Your friends and family are separated from you, and you only have yourself to depend on.
The dog house represents how things are not going well for the person who has the dream. In this case, it may be because of a break up that has left them feeling angry and upset.
