To be honest the posters situation is as most regulars advise a good age gap between the dogs,a nd also only one entire male, and the bitch is as yet a puppy so no reason fro conflict, which is unlikely with the other males being castrated.
When the bitch matures it is very likely that she will be noticeably the boss ;)
Things do change and evolve in a multi-dog household. I have found this with up to five generations of bitches living here with the occasional visiting dog or bitch too.
Generally age determines rank, but when a younger dog reaches full social maturity at around 4 and there is a vacant slot higher up if they are that kind of character they will take it.
I have twice noticed younger dogs gaining a higher place than their mothers who were not politically motivated. I have also had an alpha an a retired Alpha sort of share top spot.
At present the one who took precedence in the canines over her now dead grandmother seems to be power sharing with her own granddaughter. Both seem to keep slightly aloof from the other two which are the younger ones mother and daughter.
Of course when they all get along, are happy to share bones and toys and attention the signs can be pretty subtle, and not very noticeable.
