Is there a possibility of utilizng doggie daycare or even hiring a dog walker while you're not home? I would not feel comfortable at all letting her urinate inside of the house. That can totally confuse her and lead to a lot of problems down the road, plus it's just not healthy for any people living in the house. If she goes on the carpet, that can soak through to the carpet pad and cause mold and other bacteria, which can only be resolved by replacing the carpet entirely. I definitely would not want her to go inside. I would thoroughly research other options, such as the doggie daycare or a dog walker.
