anyone have experience dealing with dog aggression?

I have had my share of dogs Doberman,Husky, Duke,english bulldog, standard poodle, and now 2yorkies for my son, the english bulldog would pick on the standard poodle I used to separate them and train them to get along during the time I was home It took alot of watching and a careful eye to their action before the aggression starts is the trick do not let her even begin your the boss and stop her before she even begins look at her where she looks and stop immediately, yes my dogs got into fights but not that bad and now they cant be apart and love each other
