Kidney Stone Symptoms in Dogs and Cats
Many pets with kidney stones exhibit no clinical symptoms at all, with the stones being diagnosed when your pet has an X-ray for another health reason or complaint. In other cases, symptoms of urinary tract infection may occur with urgency and/or blood in the urine. Kidney stones may cause sudden colic (abdominal pain). This may be due to the small stones leaving the kidneys and plugging the ureters, the tubes that come out of the bladder.
The most important test for diagnosing kidney stones is an abdominal X-ray that includes the kidneys. While urine analysis may identify crystals, removal of the kidney and stone analysis is often the only way to definitively diagnosis stone type.
