What Breed Is My Dog?

We adopted this cutie a month ago from a shelter. The people at the shelter said they thought she was some kind of terrier mix. When I look at her, I see a lot of Dachshund, except for the curly tail, and her ears, now that they've started sticking up. We think she might have some Pug also. The first image was taken the day we got her. The last four were taken today. Anyone have any ideas?
