It wont last long, but as others have said it's basically the same as having a baby. Count your lucky stars that she's well behaved and waking you when needing to go. I had a dog once that, even at nearly 4 yrs old, would still mess inside. Our new little guy is just over 12 months old and has been a blessing. After the settling in he hasn't had one accident inside. In the first two weeks I was up every few hours taking him outside to make sure he would get the idea, now we can be gone all day and come home to a clean laundry (this is where they stay when we aren't home). It's all about sticking with it, even if you have to have an afternoon nap to catch up on sleep. Putting pup in her crate for an hour while you nap will help keep you sane.
