That's funny
. Lots of animals are that way ... they don't want to "go", but they will lead the way when it's time to head back home. Perhaps you can fool her by carrying her the distance out, but having her walk back? Eventually she'll want to do both legs of the walk, once she gets used to the smells and stuff.
BTW, what's she walking on? If she's spent her whole life on carpet and grass, concrete may feel alien to her. And watch her little feet when summer comes and the concrete gets hot ... she'll burn her tootsies.
