Xanthinuria is an uncommon metabolic disorder clinically manifested as uroiithiasis. There are two forms of the disease, Congenital and iatrogenic. The former was diagnosed in a four‐year‐old dachshund bitch. The patient was presented with signs of terminal chronic renal failure. Urine was bacteriologically sterile with massive amorphous crystaliuria. Bilateral nephroiithiasis was diagnosed at necropsy. The kidneys were shrunken with marked atrophy of the renal cortex and medulla. infrared spectrometry revealed that the stones comprised 100 per cent xanthine. Later, two of the patient's siblings were examined for urine xanthine content; both showed higher concentrations of xanthine than a control dog. The described case is compared with seven known published cases of Congenital xanthinuria.
