I have had Coco, my chihuahua for about 3 months now. She is about 11 months old. She usually does so good about going outside to potty. She has learned to even go over to the door and scratch when she wants out. But...for the past week, every night she will go into the living room, (she sleeps at the foot of my bed) poop in the floor, then start barking like a crazy dog. Once I get up, go into the living room, clean it up, she will run back to the bed and sleep. I don't hear her get up until she starts barking AFTER she poops.
My husband has thinks I'm crazy because I told him it's just like she does it, then barks to laugh at me lol. Any suggestions on how to fix this? It is really getting on my nerves!!!

This behavior has only started the past week. Nothing has changed that I'm aware of. I just don't know how to correct it.
