Our strategy consists of two complementary approaches: i) the direct search for stellar substructures around dwarf galaxies through deep wide-field imaging, and ii) the characterization of the chemical properties in these systems up to large galacto-centric distances. We show our results for two star-forming dwarf galaxies, the starburst irregular NGC 4449, and the extremely metal-poor dwarf DDO 68.STAMPAenConference paper10.1017/S17439213160090172-s2.0-85016461651000456234800071https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/accretion-phenomena-in-nearby-starforming-dwarf-galaxies/6E135E0F76071804ECB3EFF3C21948EB2017IAUS..321..211AFIS/05 - ASTRONOMIA E ASTROFISICA
