There is no one I’d want to have him, more than you.
Alas, male Dobes are not fond of other male dogs, either.
You’re right
Big guard type males are territorial ....it’s just what they are
Females too sometimes don’t like each other ....
I’ve had male with female and if she’s fixed it’s easier....if not then twice a year it’s Moon River
I’ve seen a male Rott submit a female but never attack one
My female American bulldog would try to kill any female animal except human or livestock
