Kidney Stones Symptoms in Dogs

Kidney stones, a condition that is also called nephrolithiasis or renal calculi, results from the enlargement of crystals formed in the kidneys. Depending on the size, location, number and movement of the stones, a dog may remain asymptomatic (show no symptoms) or display a variety of symptoms indicating illness.

  1. Recurring Infections

    • Repeated diagnoses of bladder infections can indicate additional canine health problems. The presence of kidney stones can result in bladder infections that are difficult to treat and often recur shortly after successful treatment.

    Urination Patterns

    • Changes in urination patterns can indicate the presence of kidney or bladder stones. A sudden decrease or increase in urination, pain, straining to urinate or blood in the urine can signify a kidney stone has moved or is trying to pass--tearing or blocking the ureter.

    Behavior

    • Normally house-trained dogs may suddenly urinate in the house in unusual locations, such as the bathroom, bathtub, tile or other cooler places. Dogs may also exhibit signs of agitation, discomfort or depression.

    Vomiting

    • Abdominal pain, colic and vomiting can result with the presence or passing of kidney stones. A dog's appetite may also decrease, and normal eating patterns may be disrupted.

    Asymptomatic

    • Symptoms of kidney stones in dogs may not be present and will only be seen when the stones attempt to pass into the bladder through the ureters.
