Personally, I would wait until your current GSD is a bit older before bringing in a rescue. A rescue might be a lot of work itself, just like an 8 month old puppy is.
That said, whenever you do get a rescue, I would think about getting a male. But all in all, it really depends on the personalities of ALL of your current dogs. (You might also want to wait until your 8 month old is an adult to see if she still gets along with your female Pap.) Female on female aggression is about the worst kind there is!
