I recommend you put some folded gauze on the lesion to stop the bleeding and tape that on. You should have this examined by your veterinarian, as there are various conditions that can cause this: 1) a coagulation disorder, 2) cutaneous hemangiosarcoma) 3) a severe bruise 4) other trauma. Depending on the size of the blood vessel that is bleeding, or the cause this may be dangerous.
