I wish I had some advice for you, but I haven't had any experience with doxies and any tendencies they have in particular. I know that Tasha used to cry when I put her in her crate and had to leave and it broke my heart but I just had to ignore it. She adjusted fairly quickly though and I got a play pen for her to be in when I was gone for long periods, which she did fine in, though she was extremely exuberant when I got home and jumping all over me, which we had to work on. To this day she has a tendency to jump when I first get home from somewhere, but she's a lot better now.

I do know that dachshunds have exceptional problem-solving abilities, which means they are very good at learning how to get their way. I'd imagine Gigi really needs to learn that her crying won't work in always getting what she wants, but it has to be difficult for you. I truly think just about any puppy left on its own has separation anxiety though. I think a lot of people here have given you good advice, and you might also search the internet about dachshunds. Look for any behavioral problems that they tend to have and how best to handle them.

One thing I would be careful of though is how much attention you give her before you are heading out. If you are cuddling and playing with her a lot just before you leave, it might not be giving her time enough to adjust to being alone. Also when you get home try not to lavish her with immediate attention and cuddles. It's hard because that is probably what you want to do, but it reinforces to her that when you are home everything is wonderful and when you are away everything is lonely.

Wish I could offer you more. Good luck!
