  The dynamical net-charge fluctuations (${\nu}_{dyn}$) in different particle
ratios $K/{\pi}$, $K/p$, and $p/{\pi}$ are calculated from the hadron resonance
gas (HRG) model and compared with STAR central Au+Au collisions at
$\sqrt{s_{NN}}=7.7-200~$GeV and NA49 central Pb+Pb collisions at
$\sqrt{s_{NN}}=6.3-17.3~$GeV. The three charged-particle ratios ($K/{\pi}$,
$K/p$, and $p/{\pi}$) are determined as total and average of opposite and
average of same charges. We find an excellent agreement between the HRG
calculations and the experimental measurements, especially from STAR beam
energy scan (BES) program, while the strange particles in the NA49 experiment
at lower Super Proton Synchrotron (SPS) energies are not reproduced by the HRG
approach. We conclude that the utilized HRG version seems to take into
consideration various types of correlations including strong interactions
through the heavy resonances and their decays especially at BES energies.
