Amber,
Charlie got used to the leash pretty quickly, but he doesn't actually walk on it the way a dog does. Maybe he will still learn to, as we have only been using it since the warm weather started. Sometimes he walks in the hall a little, but as soon as we get outside I pick him up to walk down the street, otherwise it would take a lifetime to get around the corner!
I like to take him with me if I have to run around the corner to the 24 hour market late in the evening. That way, he gets really tired from the adventure and I am sure to get a tranquil night's sleep!
