Modern hydrodynamical simulations show that stellar feedback in dwarf galaxies can drive large quantities of metals out of the galaxies following episodes of star formation. And these metals may now be retained in the circumgalactic medium (CGM) or have lost to the vast intergalactic medium. In this talk, I'll show recent progress to consistently assess the retention rate of metals in the CGM of nearby dwarf galaxies. I will also discuss observational efforts to capture metals flowing out of dwarf galaxies in action and quantify the relation between outflows and stellar feedback strength at a low-mass regime.
