We present here far-infrared photometry of galaxies in a sample that isrelatively unexplored at these wavelengths: low-metallicity dwarf galaxies withmoderate star formation rates. Four dwarf irregular galaxies from the$\mathrm{L{\small{ITTLE}}}$ $\mathrm{T{\small{HINGS}}}$ survey are considered,with deep $\textit{Herschel}$ PACS and SPIRE observations at 100 $\mu$m, 160$\mu$m, 250 $\mu$m, 350 $\mu$m, and 500 $\mu$m. Results from modified-blackbodyfits indicate that these galaxies have low dust masses and cooler dusttemperatures than more actively star-forming dwarfs, occupying the lowest$L_\mathrm{TIR}$ and $M_\mathrm{dust}$ regimes seen among these samples.Dust-to-gas mass ratios of $\sim$10$^{-5}$ are lower, overall, than in moremassive and active galaxies, but are roughly consistent with the broken powerlaw relation between the dust-to-gas ratio and metallicity found for otherlow-metallicity systems. Chemical evolution modeling suggests that these dwarfgalaxies are likely forming very little dust via stars or grain growth, andhave very high dust destruction rates.
