We consider a classical dipole gas in the grand canonical ensemble. We prove that in dimensions greater than or equal to three, and for all temperatures, the free energy and the charges-dipoles correlation functions have an expansion in powers of z, the fugacity of the system, which is asymptotic to all orders. We also give some information about the decay of correlations.
