yeah she just needs more practice so she understands that the way she played with her littermates isn't how she is supposed to great others. Take her EVERYWHERE, so she isn't afraid of anything if there is something that startles her dont comfort her just confront the fear, for example when mine was a pup lawn mowers scared him, so everytime i'd see or hear one he'd run behind me and i'd pick him up and nudge him forward, with the help of several neighbors and ppl in the neighborhood, he got over it now he doesn't even notice when we pass one by. If she's being akward with other pups the only way to fix it is by letting her play with more dogs, check to see if there's a puppy play group at your local shelter, mine offers them weekly for pups and dogs of different sizes
good luck.
