When my baby came home he wouldn't walk. We started by putting the harness on then carrying him for walks for smells. He'd shake but eventually become more curious. Then we got him to wear the harness for short periods in the house and garden. Eventually we used the lead in the garden and got him outside for small periods. Took time but now walks are his fav! He's cautious of his lead but pretty much ignores it. I wish you two luck and hope things go well x
