Urinary Tract Stones/Crystals Made Up of Uric Acid in Dogs

Urolithiasis/Urate Stones In dogs

Urolithiasis, a medical condition characterized by the presence of stones or crystals in a dog’s urinary tract, can pose significant health concerns, particularly when the stones consist of uric acid, termed urate stones. These stones may manifest in the kidneys or the tubes connecting the kidneys to the bladder, known as ureters.

Although any dog breed can be affected by urolithiasis, certain breeds such as Dalmatians, English Bulldogs, and Yorkshire Terriers exhibit a higher susceptibility to the condition. Moreover, urolithiasis tends to occur more frequently in male dogs than in females, typically surfacing within the initial three to four years of life.

Treatment of urate stones is often necessary, but recurrence of the condition is common. Despite the likelihood of recurrence, the overall prognosis for affected animals remains positive with appropriate management and care.


Although many dogs may not display any signs of the disease, the most prevalent symptoms typically relate to urination problems. These may encompass irregular urine streams, challenges with urination (dysuria), presence of blood in the urine, cloudy urine, and ultimately the inability to urinate altogether (anuria).


Dogs with an abnormal connection of the primary blood vessel in the liver, known as a portosystemic shunt, are more prone to developing such stones in the urinary tract. Additionally, a diet rich in purine—present in beef, poultry, and fish—can contribute to this condition.


Ultrasounds are frequently conducted to ascertain the dimensions, configuration, and positioning of the stones. This aids the veterinarian in devising an appropriate treatment plan. Additionally, blood tests are conducted to identify any underlying medical conditions contributing to the formation of the stones.


When a dog experiences urinary blockage, surgery is typically necessary. If the dog has a portosystemic shunt—a previously mentioned abnormal connection of the main blood vessel in the liver—surgery may be conducted to redirect blood flow.

In some cases, medications are prescribed to dissolve the stones, a process that typically takes around four weeks to fully resolve the condition.

Living and Management

Regular monitoring for stone recurrence involves undergoing ultrasounds and X-rays every two to six months. Early detection often enables straightforward treatment of the stones without surgical intervention.


Adopting a low purine diet has demonstrated effectiveness in preventing the formation of these stones.
