Poor Bella! This looks like a hotspot. Hot spots occur when an animal scratches or chews at an area until damage is done to the skin. They can often progress very quickly and become quite severe if not treated. If the area is continuing to enlarge or if Bella seems uncomfortable I would recommend that you have her seen by your veterinarian. Your veterinarian may clip and clean the area and prescribe medications to help it heal. In the meantime I would recommend that you try to prevent Bella from scratching at the area.
