Welcome to YorkieTalk. I agree, no collars. Use a short nylon leash, no flexi or retractable leashes. This will help you in gaining control of the walk.
If you haven't already, I would try a basic doggy obedience class with Miko. Work with her inside your home on basic commands like sit, stay, and "watch me." Then move outside and work on these commands. The training will help focus Miko on you. Use a really yummy treat or special squeaky toy that you reserve for walks only.
Try extending the length of your walk. Miko may relax sooner if she knows that her walk won't be brief and the fun won't be fleeting.
My boys are sometimes really excited when they first get out the door and it takes some work to relax them. If they start pulling hard, I stop and make them sit and tell them "settle down." When they relax, we start moving again. Sometimes it takes many stops before they settle into a nice rhythm.
