The satellite populations of Milky Way--mass systems have been extensively studied. However, the satellites of lower-mass dwarf galaxies remain largely unexplored, despite hierarchical structure formation predicting that dwarf galaxies should host their own satellites. In [Li et al. (2025a)](https://ui.adsabs.harvard.edu/abs/2025arXiv250408030L/abstract), we present the first results of the ELVES-Dwarf survey, which aims to statistically characterize the satellite populations of isolated dwarf galaxies in the Local Volume ($$4<D<10$$~Mpc). We identify satellite candidates in integrated light using the Legacy Surveys data and are complete down to $$M_g\approx -9$$ mag. We then confirm the association of satellite candidates with host galaxies using surface brightness fluctuation distances measured from the Hyper Suprime-Cam data. We surveyed 8 isolated dwarf galaxies with stellar masses ranging from sub-Small Magellanic Cloud to Large Magellanic Cloud scales ($$10^{7.8} < M_\star^{\rm host}<10^{9.5}\, M_\odot$$) and confirmed 6 satellites with stellar masses between $$10^{5.6}$ and $10^{8} \, M_\odot$$. Most confirmed satellites are star-forming, contrasting with the primarily quiescent satellites observed around Milky Way--mass hosts. By comparing observed satellite abundances and stellar mass functions with theoretical predictions, we find no evidence of a "missing satellite problem" in the dwarf galaxy regime.
