  We numerically generate, and then study the basic properties of dark
soliton-like excitations in a dipolar gas confined in a quasi one dimensional
trap. These excitations, although very similar to dark solitons in a gas with
contact interaction, interact with each other and can form bound states. During
collisions these dipolar solitons emit phonons, loosing energy, but
accelerating. Even after thousands of subsequent collisions they survive as
gray solitons and finally reach dynamical equilibrium with background
quasiparticles. Finally, in the frame of classical field approximation, we
verified, that these solitons appear spontaneously in thermal samples,
analogously to the type II excitations in a gas of atoms with contact
interaction.
