You can start training to walk to heel in your garden without the lead on. That way she
can't pull, and learns to watch you - and equally you learn to concentrate on her as well, turning and calling her to you when she gets too far from you so that she has to catch up again; the time when some people would pull on the lead to get the puppy back to the right position. If you make following you offlead a game, it'll be much easier for her to do the same on lead.
They all hate wearng a lead to begin with, often flapping about like a fish on a line. But the horror soon wears off if they're not pressurised to walk at first.
