We show the results of numerical simulations of dwarf spheroidal galaxies (DSphs), which allow to understand their evolution in the framework of no internal virial equilibrium. Under this hypothesis, we reproduce with a low dark matter (DM) model the high values of the virial M/L ratio measured observationally for these objects. In this work, we present a model of the Sagittarius (Sgr) DSph, with all its observational features.
