The behaviour of the topological susceptibility χ in QCD with two colours and 8 flavours of stag- gered quarks is studied at nonzero temperature on the lattice across the finite density transition. It is shown that the signal of χ drops abruptly at the (pseudo-)critical chemical potential µ c , much as it happens at the finite temperature and zero density transition. The Polyakov loop and the chiral condensate undergo their transitions at the same potential µ c . At a value µs of the chemical potential, which satisfies µs > µc , Pauli blocking supervenes and the theory becomes quenched.
