The length of the risk of a dog getting stuck after eating a fish bone depends on the location of the fish bone and whether there is internal bleeding. If it gets stuck in the throat or other parts of the body, it is generally not life-threatening. The same is true if it gets stuck in an organ. However, if it gets stuck in the trachea, it will cause severe respiratory symptoms. The most dangerous thing is that the fish bone enters the chest, which may cause puncture wounds and infection. The most serious thing is to puncture the heart, which can cause internal bleeding and other conditions. X-ray examination is required to determine whether it is dangerous.
