Sasha is ADORABLE! Yeah, I think the leash trailing and then the 'letting her walk you' aspect is one of the best ideas. It really IS a scary world out there. Keep up the praise when she does well. Soon, she'll be pulling you along with her. (Of course, we don't really want THAT, but she'll get used to the big old world as time goes by.)

If she's up to date on her shots, start taking her lots of places and make them positive experiences. Give her time to look around and see what's what. She'll be much calmer after a while and a much more confident dog in the long run.

Do be aware, though, that a "scare period" is coming up. At about 4 months, they go through this period when if something scares them, they tend to remember it as scary. Try to stay as positive as possible and patient with her. Think it sounds like you're on the right track with that darling girl.
