OP, this has been going on too long, with too many excuses.
For those who may have missed the initial thread:

Your dog is incontinent, or has the implications that come along with being incontinent, meaning she is urinating in the house. There may be medications that will assist with her having a little better ability to hold it.
That being said, out of eight times a day, I suspect you could take her out for at least 5- first thing in morning, lunch, after work, mid evening, before bed.
In my mind, inconvenience doesn't trump hygiene. If you're not ready to let her go, then you need to find a solution that works for everyone in the home, without destroying your house in the process.
