We generalize existing constraints on primordial black holes to dark objects with extended sizes using the aLIGO design sensitivity. We show that LIGO is sensitive to dark objects with radius $O(10\ensuremath{-}{10}^{3}\text{ }\text{ }\mathrm{km})$ if they make up more than $\ensuremath{\sim}O({10}^{\ensuremath{-}2}\ensuremath{-}{10}^{\ensuremath{-}3})$ of dark matter.
