  We consider the resummation of large electroweak Sudakov logarithms for the
annihilation of neutralino DM with $\mathcal{O}$(TeV) mass to high-energy
photons in the minimal supersymmetric standard model, extending previous work
on the minimal wino and Higgsino models. We find that NLL resummation reduces
the yield of photons by about $20\%$ for Higgsino-dominated DM at masses around
1~TeV, and up to $45\%$ for neutralinos with larger wino admixture at heavier
masses near 3~TeV. This sizable effect is relevant when observations or
exclusion limits are translated into MSSM parameter-space constraints.
