Just like humans, dogs can experience a number of issues that require medical attention. One such issue is an intestinal obstruction. An intestinal blockage in a canine is very serious and can be fatal if the dog is not treated promptly by a veterinarian. Thus, if your dog has an intestinal obstruction, it is essential to take it to an animal hospital right away. In the event that your dog has consumed something that is too large to be passed during a bowel movement, surgery will likely be needed.
