The length of the danger period for a dog stuck with a fish spike depends on the location of the stuck area and whether there is internal bleeding associated with it. If it gets stuck in the throat, etc., it is usually not life-threatening, as is getting stuck in an organ, but getting it stuck in the trachea can cause severe respiratory symptoms. The most dangerous is the entry of a fish spike into the chest cavity, which may cause a puncture wound and result in infection. The most serious is the puncture of the heart, which can cause internal bleeding and requires an X-ray to determine the risk.
