What is wrong with my dog?

She’s a German Shepherd between 9 – 11 years of age (not sure how old she was when she was given to us.) She is the most well behaved dog in the universe. Lately though she has refused to go outside when we ask her to, and a few minutes later she’ll pee a lake on the kitchen floor.
This morning she refused to go outside. About 10 minutes later Rick says, “What’s Dakota doing in the bathroom?” It was just an odd place for her to be.
I said, “She probably WANTS to go to the bathroom…” and sure enough, she’d peed in the bathroom.
She just started doing this about 2 weeks ago. The only thing I can think of that might be relevant is I was on the back deck when I saw her come back in through a hole she’d punched in the wooden fence. I got up and went back through the house to the sliding glass door to go out and find something to block the hole. Well, when I opened the door Dakota tried to come in. I told her she needed to stay out side….but she forced her way in. I was flabbergasted. She has never disobeyed me before. I tried and tried to get her to go back outside and she just refused.
Looking back, I’m wondering if something had scared her and that was why she so desperately wanted to come back in. Ever since then, she has refused to go outside unless Rick comes down and forces her to.

Now, when she’s outside, she doesn’t chase the squirrels or anything. She just goes under the deck and lays down.

She hasn’t pooped in the house, though.
