I think your dog has matured a lot since seven months old. Lots of dogs are butt-heads when they are teenagers. But with training and exposure, they learn to put their faith in you, and they also learn that everything isn't so scary. I think you need to catch up to her. I think she has gotten over herself a bit. There is nothing wrong with being cautious, you should be, practice keeping a safe distance between your dogs and others (human and canine), but also practice confidence. Because if you are nervous about what your dog will do, that is transmitting right down the line.
Think of it this way. If you boss tells you to do ABC, you go and do ABC. If your boss hesitantly tells you to do ABC, then it makes you a little hesitant too. Should I do this? What might go wrong? Why is he so worried about this? Dogs pick up on stuff, pharomones make a breath smell funny. They tell you to pop a peppermint in your mouth at the dog show, to mask the fear smell. Because WE can throw our dogs off.
