Waters I live with and train dominant dogs by choice. I like dominant dogs. Dominance is not necessarily a bad trait. It is a trait that can cause trouble if it is allowed to get out of control. Dominance is not aggression.
Dominance is a desire to run things.
Aggression is the desire or intent to cause harm. The aggressive dog intends to hurt or damage another living being. Sometimes a dog may exhibit both dominance and aggression. Some may only show one of these attitudes. With any dog that has shown aggression be careful.
