Preparing for first walk

Hi everyone!

I’ve got a female toy poodle who’s now fully vaccinated and ready to start exploring the world 🐶

She’s comfortable wearing her harness and doesn’t seem bothered by it at all, but as soon as I clip the lead on, she sits down and will not walk. I’ve tried practicing both inside the house and in the back garden with the same result.

Does anyone have tips for helping a puppy get used to the lead and preparing her for her first proper walk?

Any advice would be really appreciated. I’m a first time puppy owner and want to get this right 🐾
