She'll grow out of it :-)
Practice swapping items in the house, for something of higher value. So if she picks up a shoe, offer her a piece of cheese and say leave. Eventually (not now) she will leave anything even at a distance and run to you to see what better thing you have.
All of mine have done this, eating any disgusting thing they can find outside, for the most part I try to ignore it and only interfere if it looks like something dangerous. If I have to try and get something off a puppy who does not yet have a solid leave I try the excited running the opposite way, with a high pitched excitable voice and yummy treats.
