dog aggression towards dogs

I have a dog that recently started to show signs of aggression towards other dogs.?
I need to know how to correct this before it's too late!
Some breeds are naturally predisposed to dog aggression so if he's in this group(usually working or herding breeds), then it'll require very careful consistent socialization early on. I have an Australian Cattle Dog so I understand your dilemma.
