Urolithiasis (Urinary Stones) in Dogs and Cats

Understanding Urinary Stones in Pets

Urolithiasis, commonly known as urinary stones, is a frequent and potentially serious condition in both dogs and cats. These stones most often form in the bladder but can appear anywhere in the urinary tract, including the kidneys, ureters, bladder, or urethra. They develop when microscopic crystals bind together and form larger mineralized stones. Factors that contribute to stone formation include diet, genetics, underlying disease, and urinary tract infections.

Signs & Symptoms of Urinary Stones

Pets with urinary stones may show a variety of symptoms, including:

  • Frequent urination
  • Straining or discomfort while urinating
  • Blood-tinged urine
  • Urinating in unusual places
  • Crying or vocalizing during urination

Because these signs can also indicate a urinary tract infection, prompt veterinary evaluation is essential to ensure accurate diagnosis and timely treatment.

How Urinary Stones Are Diagnosed

Your veterinarian will begin with a detailed history and a full physical exam. Diagnostics typically include:

  • Urinalysis – checks for infection, crystals, blood, and inflammation
  • Imaging (ultrasound and/or X-rays) – identifies the type, size, and location of stones

Urinalysis and imaging are commonly performed together, as infections and stones often occur at the same time and may influence treatment decisions.

Treatment Options for Urinary Stones

Treatment depends on the type, size, and location of the stones:

  • Surgical removal – recommended for stones that are too large to pass, causing obstruction, or not dissolvable
  • Prescription urinary diet – can dissolve certain types of stones over time

To reduce the risk of recurrence, most pets benefit from long-term dietary management, consistent hydration, and routine veterinary monitoring.
