Answer: Internal bleeding refers to bleeding into internal organs or into the chest or abdominal cavities. It usually follows crushing or a severe impact injury such as a fall or kick or from involvement in a road accident. The fact that haemorrhage is occurring may not be evident until signs of shock appear; this is usually become blood cannot reach the exterior. However, at times blood may be seen. Frothy blood appearing at the mouth or nostrils suggests bleeding from the lungs or air passage. Vomited blood usually comes from the stomach and appears dark brown because of the action of stomach acid. Extensive bleeding from deep within the ear canal strongly suggests an injury inside the skull. Sometimes blood may be apparent in the urine or motion after an accident.
Regrettably, it is not possible to stop an internal haemorrhage with first aid treatment. The best that can be done is to treat the animal for shock, wipe any frothy blood from the mouth and nose to keep the airway clear and to obtain the assistance of veterinarian as soon as possible.
