Dwarf spheroidal galaxies (dSphs) are nearby laboratories to study galactic interactions and the dark matter content of individual galaxies. We present an MCMC based method to study the dynamical evolution of the dwarf galaxies in the presence of galactic tides, that will help breaking the mass-orbit degeneracy of the dwarfs. A sub-set of the results for the Carina dSph is presented as a case study, where we investigate its total mass and the effect of using different dark matter halo profiles to model the dSph.
