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:
- defining a place where she could do pee, first with journal papers, a "kind-of-a-diaper-sheet";
- dropped a few drops of a special product that makes dog pee on paper;
- 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;
- 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.
