Loose leash walking achieved after 4 months - what clicked

For months I struggled with loose leash walking. Tried everything. What finally worked was a combination I havent seen anyone recommend together:

1. Silky leash (the material matters - those thin nylon ones made me tense up which made my dog tense)
2. Treats held at my side, not in front of their face
3. Literally just stopping dead when she pulled. Every. Single. Time. No yanking, no correcting, just stop.
4. Walking at HER pace, not mine

The stopping thing took forever at first. Our 20 min walk took an hour. But after about 2 weeks she figured out that pulling = we stop = boring. Now she checks in with me constantly and walks beautifully.
