Semi-success report!
I started feeding Gia tiny bites of pineapple, and she's eating it! I also bought these delicious looking doggie cookies (they look like REAL cookies!) and when she does her poo on the pad, I call her over and give her a piece of the cookie. This is more time consuming for her to eat, so she takes it to her "rug" area to crunch it, giving me time to clean up her poo!
So far so good! I'll post again in a week and update!
Thank you everyone!
