Don't confuse aggression and assertiveness. Have rules, and stick to them. I can scream and yell at my dog all day long because he pulls on the leash, but I'll just be angry and the dog will continue to pull on the leash. If I'm calm, kind, but firm, I find it's usually quite a bit more effective. I'm not getting angry, but if my dog wants to keep walking, he's got to calm down first. I'm willing to wait.
