Ah... yes, that can be a problem. You might want to find some "puppy pee pads" and use them... and get after her if she starts tearing them up. (ok, by "get after", I mean "scold firmly, and distract with a toy to chew on instead")

They really *can't* "hold it" for long at her age, and it will prevent her from trying to "hide" it from you, because she clearly already knows she's not supposed to poop or pee on the floor!
