Magnetic anisotropies in quantum dots (QDs) doped with magnetic ions are
discussed in terms of two frameworks: anisotropic $g$-factors and
magnetocrystalline anisotropy energy. It is shown that even a simple model of
zinc-blende p-doped QDs displays a rich diagram of magnetic anisotropies in the
QD parameter space. Tuning the confinement allows to control magnetic easy axes
in QDs in ways not available for the better-studied bulk.
