In this talk, I will discuss recent experimental progress in cooling of atomic dipolar Bose gases and give an overview of their basic phenomenology. I will then discuss some recent work on the damping of low energy quasi-particles in a weakly interacting dipolar Bose condensates, at zero and finite temperature. In particular, I will show that damping processes which are typically active in Bose condensates with short-range interactions, are absent, or highly suppressed in the dipolar gas, owing to the peculiar nature of its low energy excitation spectrum. I will then discuss the far-from-equilibrium dynamics of dipolar Bose gases and show how quantum quenches can be used to probe the underlying excitation spectrum of a dipolar gas.
