It is known that cold dark matter candidates lead to the structuring of matter on scales much smaller than typical galaxies. This clustering translates into a very large population of subhalos in galaxies, which must impact predictions for indirect searches of annihilating dark matter. I present a model (arXiv:1610:02233) consistently describing the subhalo population in a dynamically constrained Galaxy. I will show application of this model to indirect searches of dark matter via antiprotons cosmic-rays using the latest data from AMS-02.
