We present HST WFPC2 images in four filters (F336W, F439W, F555W, F814W) of Seyfert's Sextet. These images reveal on the order of one hundred extended sources in total, some of which appear to be associated with the four interacting galaxies. We determine the colors and surface brightness profiles for the sample and subsequently weed out background sources based on the available data. In this poster, we present these extended sources and compare their properties with those of dwarf galaxies in other similar systems, such as Stephan's Quintet and also with the properties of Local Group dwarfs. The broadband colors of the dwarf galaxies are compared with expectations from stellar population models as well as to the population of globular cluster candidates in the system in order to study the star formation history of the group.
