We present preliminary results of a search for candidate dwarf galaxies in the NGC 3665 galaxy group. A $0.1 \times 0.1$ Mpc$^2$ field around the dominant early-type galaxy NGC 3665 was investigated using BRI images from the 2.5m INT WFC archive. A search with the SExtractor yielded 148 dwarf galaxy candidates in the range $-12 > M_B > -16$. The resulting luminosity function for the group can be described by a standard Schechter function.
