The success rate of intestinal blockage surgery in dogs is generally quite high, especially for simple cases. For surgeries involving a single incision into the intestines, for example, the success rate is over 94%. The success rate may vary depending on factors such as the location and size of the blockage, the dog’s overall health, as well as how soon the surgery is done after the blockage is identified.
If the surgery is more complicated,  involving multiple incisions or removing parts of the intestines, the risk of complications rises. Timely diagnosis and treatment are critical for good outcomes.
