While she was boarded in the Taiwan vet office, Miko worked with a volunteer who trained her to walk on leash. Robin, Miko's original fosterer, helped to get Miko more comfortable walking in a new environment.
The result was that Miko was fantastic on leash when we walked her for the first time, together with Boomer & Phoebe. Miko does a great heel, virtually never pulls, and follows whoever is holding the leash without hesitation. Even when she's scared of that person. It's almost like it's been ingrained in her that she must follow the leash-holder no matter what.
See all that pink she is swathed in? Since she's a fearful dog and a high flight risk (and I have already dealt with way too many dogs who have bolted when startled), Miko wears both a harness and a martingale collar, with a separate leash attached to each. I've heard too many stories of people saying, "They slipped out of their collar" or "They got out of their harness." One of those stories ended tragically with the dog being fatally hit by a car.
(That's not a happy face, that's a panting "I'm still anxious" face.)
During the walk, Miko had to walk past strangers and endure a radio blaring. She did not spook at all, though I think a part of that had to do with the fact that she was walking within a calm pack.
