Dog has Started Pooping in the House?

I have two dogs and my Poodle, who never potties in the house, has started pooping in the house. I let them out and take them on walks and she still does it. Sometimes right after we have been out for a while. Her daddy just started working and I am wondering if that is the reason. He was in college and was home with her before. I have always worked, but now I am at home. What can I do to fix this problem? She is very head strong and I am wondering if she is doing this out of spite. What should I do to get her to stop?
