If you dream of a dog barking at something, it usually means a warning. The dog barks because it sees something that is threatening. The dog is able to sense extraordinary input from different wavelengths of sight and hearing. The barking dog is a sign of something that needs attention to be focused on.
There is an English idiom that says, “barking up the wrong tree”. It means attention is given to the wrong area, while the right area is being ignored. This idiom comes from a common occurrence where a dog can loose the scent it was tracking. The scent suddenly disappears and the confused dog barks up the wrong tree, because it thinks that is the location of the prey.
