The immediate cause of death

Benign hematoma or deadly cancer, what most commonly leads to death around the time of the operation in the 8 percent of dogs who die in the hospital is either bleeding in overdrive or clotting in overdrive. If there’s bleeding in overdrive, it’s not just in the spleen but also all over the body. The bleeding at the site of the spleen consumes the dog’s clotting factors in an all-out effort to staunch the flow of blood, so the dog now becomes prone to bleeding in other areas of the body. It’s called coagulopathy.
