I just recommend learning to look at why did my mind bring that up. There is a message, the two dogs could well have been two people who are working together to take you in the wrong direction for you.
I find much more power in accepting the images and looking for the message. Sometimes the message needs to be given in a way that you will notice it. Trying to say, no I don't want images like this I refuse to see them will only create worse until you notice that the mind is receiving a message. How else can we possibly receive information?
