Personally, I don't carry dogs. Mine walk on their own 4 good feet.

It very much sounds as if you have a timid pup which means you will need to be clever in how you deal with her. Instead of trying to urge her on, which can make her balk even more, why not try something like this.

Give her a taste of some cheese from a wrapped slice. Heck, give her a couple of bites. Then leaving her sitting in the door way or where she can see you, go outside and sit down just out of reach (not hanging on to the leash at all or putting physical pressure) and start fiddling with the cheese, eating some yourself and maybe having a happy conversation or singing a song to yourself (without looking at her except for perhaps a very brief glance). The chances are, she will become intrigued enough to venture out to join the party you are having. Again, no pressure as that builds anxiety in the timid dog. When she finally comes out, offer her a bit of cheese and a happy hello, and continue to snack on it yourself. Turn and go back in the house. Keep repeating this until you've traveled a bit further from the door each time.

Something of this sort should work. You will need to be creative and always keep in mind that forcing builds resistance.
