While working with Dr. J. E. Weinman, Lincoln, Nebraska, I was fortunate to observe a urinary calculus in a female Airedale. The patient was brought to the hospital with the history of constant attempts at urination and dripping of urine for over eighteen months. In bringing the animal from the car to the hospital it made frequent attempts to urinate with only a few drops as the result.
