  In this paper we obtain the bispectrum of dark matter density perturbations
in the frame of covariant cubic Galileon theories. This result is obtained by
means of a semi-analytic approach to second-order perturbations in Galileon
cosmologies, assuming Gaussian initial conditions. In particular, we show that,
even in the presence of large deviations of the linear growth-rate w.r.t. the
{\Lambda}CDM one, at the bispectrum level such deviations are reduced to a few
percent.
