EDIT: I will copy and paste my response to you here from the other thread as well
I would start your own thread so you will get more responses but if your boy is showing dominance then your going to have a problem if you don't nip it in the butt now with a good trainer. If you have an intact bitch in the home you are asking for trouble and as he matures if you have no plans neutering him then he could really start showing more aggression especially when he starts smelling a bitch in heat in the home. Why is your bitch not spayed? Do you plan on spaying her? Pyometra isn't anything to chance because the older they get the more chance of them contracting the infection. I hope one dog or both are getting fixed eventually or you could also have an accidental litter which the world doesn't need as well

Not saying you aren't responsible but accidents do happen. Also if your male is showing HA or PA as you say then most people would agree that he should be PTS especially where he is a young pup. I've owned an HA dog in the past he was a cattle dog but he loved his family and never showed any aggression towards us. If he did I wouldn't have thought twice about putting him to sleep. To much of a risk/responsibility when you own a HA dog but even more of a risk if they want to bite the hands that feed them. Aslo, with two bulldogs in the home I hope you plan on crating and rotating if he is also showing DA. I would never leave them unattended and crate both of them when no one is home. Even having the opposites of sex in a two dog home is no guarantee that they will always get along.
