Puppy doesn’t want to go outside, now what?

It is very cold and snowy in Wisconsin and the puppy doesn’t like freeze. Understandable but it makes potty training hard. She’ll often hold it for too long just to avoid outside. When she’s really got to go, I still have to carry her out, and then she’ll often go.

I have sweaters and booties which she hates but help her stay out beyond five seconds. But here’s the question, how do I teach her to ask to go outside when it’s the last thing she wants?!! I have a bell, and I have gotten her to ring it but then I open the door and she runs 😂 poor baby.

How long did it take before your puppy understood that potty goes outside, versus just getting lucky she went while you took her out? Once she understands I think this problem gets easier to manage.
