It's a bit too soon to begin her training. You need to let her settle in and bond with you first. Give her a couple of weeks. Start with putting a large light weight rubber band on her neck to let her get the feel of something around her neck. When you put the lead on her let her drag it around the house with you keeping a close eye on her. Then pick it up and let her lead you around before making her do what you want her to do.
