We investigate current fluctuations in a three-terminal quantum dot in the sequential tunneling regime. Dynamical spin-blockade can be induced when the spin-degeneracy of the dot states is lifted by a magnetic field. This results in super-Poissonian shot noise and positive zero-frequency cross-correlations. Our proposed setup can be realized with semiconductor quantum dots.
