  According to the $\Lambda$ cold dark matter model of galaxy formation, the
hierarchical assembly process is scale-free and interactions between galaxies
in all mass ranges are expected. The effects of interactions between dwarf
galaxies on their evolution are not well understood. In this study, we aim to
understand the effect of low-mass galaxy interactions on their star formation
rate (SFR). We estimated the SFR of 22 interacting and 36 single gas-rich dwarf
galaxies in the Lynx-Cancer void region using their far-ultraviolet (FUV)
images from the GALEX mission. We find an enhancement in SFR by a factor of
3.4$\pm$1.2 for interacting systems compared to single dwarf galaxies in the
stellar mass range of 10$^{7}$ - 10$^{8}$ M$\odot$. Our results indicate that
dwarf - dwarf galaxy interactions can lead to an enhancement in their SFR.
These observations are similar to the predictions based on the simulations of
dwarf galaxies at lower redshifts. Future deeper and higher-spatial-resolution
UV studies will help us to understand the effect of dwarf galaxy interactions
on the spatial distribution of star forming clumps and to identify star
formation in tidal tails.
