Hi ! It is difficult to tell 100% from the pictures as you only can only gather some information. It does look like the black scab is necrotic (dead ) tissue, possibly due to lying on a hard surface for prolonged periods of time. The necrotic tissue has partially come off exposing some live and bleeding tissue. This is my impression ! I would recommend to have Riabow checked over so that she can receive some treatment, this wound will cause lots of discomfort !
