How old is Sadie now?
I was the same way, when all of a sudden I thought about it and Bella had not had an accident for a while. She only pooped in the house one time as a puppy (she was angry because I had scolded her). That one time, she pooped on my rug. I put her outside, but when I brought her back in, she had held the remainder of her business and proceeded to finish the poop. She was really angry with me!!
Now, the peeing was a lot worse. She was peeing in one side of her crate. I used a divider to make it smaller, but it continued. I finally began feeding her in her crate, and it didn't take any time before she finally quit messing where she ate!
