Does she not walk at all, or does she pull? If she pulls, practice “be a tree.” The instant she puts tension on the lead, stop. Don’t move until she relaxes the lead herself. She’ll learn that if she pulls, she doesn’t get where she wants to go. You can train this by putting something she really wants on a chair- a treat or a favorite toy. Start about 20 feet away and walk toward the chair. If she pulls, go back to the start line and start again! The first few attempts will take a while, but then she will catch on. The important thing is to be consistent- if she pulls, she doesn’t get what she wants.
