  We explore the possible signatures of dark matter (DM) pair annihilations in
the nearby dwarf spheroidal galaxy Draco. After investigating the mass models
for Draco in the light of available observational data, we carefully model the
DM density profile, taking advantage of numerical simulations of hierarchical
structure formation. We then analyze the gamma-ray and electron/positron yield
expected for weakly interacting DM particle (WIMP) models, including an
accurate treatment of the propagation of the charged particle species. We show
that unlike in larger DM structures - such as galaxy clusters - spatial
diffusion plays here an important role. While Draco would appear as a
point-like gamma-ray source, synchrotron emission from electrons and positrons
produced by WIMP annihilations features a spatially extended structure.
Depending upon the cosmic ray propagation setup and the size of the magnetic
fields, the search for a diffuse radio emission from Draco can be a more
sensitive indirect DM search probe than gamma rays. Finally, we show that
available data are consistent with the presence of a black hole at the center
of Draco: if this is indeed the case, very significant enhancements of the
rates for gamma rays and other emissions related to DM annihilations are
expected.
