For goodness sake, hon, at 8 weeks your dog is merely an infant, should still be with her mother and littermates and with too under-developed a brain, bladder/urethra or bowel/anus to even retain much of anything due to her infant states, let alone retain much you teach her! And teaching a dog to go potty where you want them to is a very slow, deliberate process. Just like an infant child cannot be expected to know what using the toilet is all about, neither can you infant dog know when and where to go potty until she grows and develops the physical ability to do it AND, once she's got the physical ability, to have a mature enough brain and reasoning to come to learn from your patient months of housebreaking training how to do what you want. Only by confining her when you cannot watch her, putting her on a regular schedule of feeding, out to potty, in to play, exercise and cuddle and back in confinement will she gradually be encouraged to learn HOW to hold herself and given the time for her bladder and brain to learn how to work together to slowly, over time, with your patient guidance, teach her that it is better for her not to soil her inside environment where she lives, plays, eats and sleeps. Right now, her anal or urethral nerves and muscles have little physical ability to hold her waste, even if she knew to do it.
But my goodness, what you are expecting is the equivalent to a newborn infant being toilet trained within two weeks of his coming home from the hospital. You baby has a lot of growing and developing to do before you can expect her to even know what toilet training is - let alone have a good enough idea what you expect of her to know where or when to "go" potty.
Go to our Puppy Library and read how to deal with puppy biting, teething and how to Housetrain a puppy. Unless you train them as they grow and develop, puppies don't know what in the world you expect of them. It is a slow process, takes a good year to get a Yorkie totally clean in the house w/out accidents. The tips for housetraining are at least half-way down or so on the page at this link:
