It looks like that growth has ulcerated, meaning the skin has become too thin and weak because of growth of the mass and is starting to break in places. It needs to be removed surgically at this point. When it's removed, it can also be sampled to determine what sort of mass it is and if further treatment is needed. It could definitely be a fatty tumor still. It's also possible to get incorrect results from a fine need aspirate, so it could be something else. Regardless, Kyo definitely needs some help with it now. Good luck and thanks for using Pet Coach.
