Pictured below is the x-ray from a dog who was having accidents in the house. The owner noticed blood in the urine as well. Look closely at the film and then answer the following questions: What is wrong with this dog? What are the dark black areas in the middle of the dog’s abdomen?
Diagnosis: Kidney & bladder stones, intestinal gas
See the bright white oval structure on the right side of the x-rays. That is many little stones in the dog’s urinary bladder. There are also a few small stones in the dog’s kidneys which are on the upper left side of the x-ray. The black areas in the middle of the x-ray is gas in the intestines and colon. On X-rays, minerals like calcium show up as white while gas or air is black. Soft tissues like muscle and internal organs are represented by shades of gray.
