Dream about catching dog draws attention to your anxiety about some real life competition that you are involved in. You need to be more alert and pay attention to what is going around you. Perhaps someone wants you to pursue a goal that you are not passionate about. This is a portent for the subconscious and the negative aspect of the Self. Some people are motivating you to do better.
Catching dog dream indicates aspects of yourself that you are hiding. You are only partially acknowledging your feelings. You are going on the wrong path. It is a hint for feelings of sensuality and tranquility. You are giving more than you are getting back.
If you dreamt about catching dog:
It will be hard for you to deal with the people around you. The mood dominating everyone will make them jumpy and sporadic. Work independently if you can. Otherwise, you may go crazy trying to work together with those who are not on your page.
