I have read a little about using melatonin in bulldogs to help with aggresion. Any thoughts on that?? My family has always done well at maintaining Alpha status with our dogs and so the aggression has never been targeted at us. Her problem seems to be with him only and is triggered anytime things escalate and get chaotic, like when someone comes in the door and they all get excited.. she always targets him.. she goes completley submisive for my boxer and will submit to us but not listen when in a fight with my male bulldog.
