The XRay below is of a little dog.

This little dog had blood in its urine every few days. A sample of the urine did not show any sign of urinary tract infection. 
 

  Look at the XRay, and try to find what the problem is:
 
 

The dog has bladder stones.

At the arrow you can see a white area. These are stones inside the urinary bladder. 

The stones cause irritation by rubbing against the bladderís lining, resulting in the blood which was seen in the dogís urine.
