We identify dynamical quantum phase transitions between different topological sectors that appear after sufficiently strong quenches of the $\\theta$-parameter. Moreover, we establish a general dynamical topological order parameter, which can be accessed through fermion two-point correlators and, importantly, which can be applied for interacting theories.
