How do your dogs react to others when out on a walk ?
They may be fine with each other due to being mother and daughter but may not tolerate another . Your pup has yet to come into season too which can cause quite a bit of friction between two bitches .
I would personally advise to wait quite a bit until your pup is older .You will then get to assess her nature better as she is still a baby yet . I have a Staffy pup aged 6 months old as well ,who is brilliant with ALL dogs he meets but I wouldnt get another until he is older.
I would say wait and see - especialy with the breeds you are considering
