How to make my dog pee inside our apartment

Question

One year ago we adopted a small female dog that we named Lola. At that time she was 1 and half years old, so now she is 2 and a half. Lola was abandoned with her puppies before being rescued. She lived for some time on a farm with other dogs and cats, probably with a lot of space to run freely.

She is a very afraid dog. She has fear of buses, people, leaves on the ground, plastic bags, brooms, thunders and so. She is a small mixed-breed dog.

By the time of the adoption, the previous owners told us that Lola was taught to not pee or poop inside the house. It's been one year now and we have tried some tricks, but with no success. We tried:

1. defining a place where she could do pee, first with journal papers, a "kind-of-a-diaper-sheet";
2. dropped a few drops of a special product that makes dog pee on paper;
3. collected her own pee and the pee of other dogs with those papers so she could understand that she can use that space to pee;
4. tried to teach command words while she was outside to make her pee or poop on demand (like a lot of videos on YouTube)

Nothing did work. Also on some days, she stays almost 10h alone at home, without peeing.

Do you guys have other ideas on how to succeed in this task?

EDIT

I am removing the "fear dog" part because I added it as a contextualization for the question, but it didn't work as expected. The main question remains: how to make my dog pee inside.

Answer 1

Some lessons are really difficult to unlearn. This is one of them. Rather then trying to unlearn don't go potty inside, teach a new lesson.

Work on the reverse of my answer at the question below. Teach your dog to use a potty pad outside. Once that lesson is learned, you then transition to the potty pad being indoors and being used.

Alternately there are a range of products that are 'indoor grass potties for dogs' these can be made or purchased. And might be a better solution.

Answer 2

My dog, a small mixed breed feared the outside when I got him. He was a rescue dog. It took time and understanding w/reassurance that it was ok. Just go to dogs level and rub both ears saying softly something soothing like its ok, youll be ok, that type of stuff. Its been 4 years and Patch is much better with less visanle fear. As for peeing in the house, try to walk her every day until she goes exclusively outside. You dont want your dog to go indoors...
