  The Alternative Left-Right Model is an attractive variation of the usual
Left-Right Symmetric Model because it avoids flavour-changing neutral currents,
thus allowing the additional Higgs bosons in the model to be light. We show
here that the model predicts several dark matter candidates naturally, through
introduction of an $R$-parity similar to the one in supersymmetry, under which
some of the new particles are odd, while all the SM particles are even. Dark
matter candidates can be fermionic or bosonic. We present a comprehensive
investigation of all possibilities. We analyze and restrict the parameter space
where relic density, direct and indirect detection bounds are satisfied, and
investigate the possibility of observing fermionic and bosonic dark matter
signals at the LHC. Both the bosonic and fermionic candidates provide promising
signals, the first in LHC at 300 fb$^{-1}$, the second at higher luminosity,
3000 fb$^{-1}$. Signals from bosonic candidates are indicative of the presence
of exotic $d^\prime$ quarks, while fermionic candidates imply the existence of
charged Higgs bosons, all with masses in the TeV region.
