We have an 11 week pup and still about the same place you are. He will go on command, "go potty", "go poop" and seems to know the difference.
Yesterday evening he is in the kitchen with my wife. He comes running into the living room, sits in front of me and cries. I jump up at take him outside, he pee'd and pooped (we have different places for each) and I never stepped off the deck. As far as I'm concerned he DID just win the Nobel prize.
He still doesn't seem to know the concept of outside only. I "think" we are making progress.... I think..... Our last Shepherd was done at two weeks with only a couple of accidents after. So it's either a male vs female thing or simply all dogs are different.
