Understanding Urinary and Kidney Health in Dalmatians

Quick answer

Dalmatians have a unique metabolism that makes them prone to specific urinary tract issues, most notably the formation of urate stones and high levels of uric acid in their urine. They are also susceptible to certain types of chronic kidney disease. Because these conditions can progress quickly, keeping a close watch on your dog's urination patterns and overall energy levels is the best way to catch problems before they become emergencies.

Hyperuricosuria

All Dalmatians naturally excrete high levels of uric acid in their urine. This is a well-recognised tendency in the breed. While this is a physiological trait of the breed, it can lead to significant health challenges, particularly in males. The primary concern is that the high concentration of uric acid creates an environment where crystals can form easily. Owners might notice their dog straining to urinate or producing only small amounts of urine at a time. Your vet will typically use a urinalysis to check for the presence of crystals and measure the concentration of uric acid. It is vital not to ignore changes in your dog's bathroom habits, as these crystals can lead to blockages that require immediate intervention.

Urolithiasis

Due to a specific mutation known as SLC2A9, Dalmatians are predisposed to developing urate uroliths, which are stones that form within the urinary tract. This is a well-recognised tendency in the breed, with male dogs being at a higher risk of experiencing clinical disease. These stones can cause significant pain and obstruction. You might notice your dog licking their genital area frequently, showing discomfort while trying to urinate, or seeing blood in their urine. A vet will use imaging techniques like ultrasound or X-rays to locate these stones. If your dog is unable to pass urine, this is a critical situation that requires emergency care to prevent bladder rupture or kidney damage.

Chronic Kidney Disease

Dalmatians are also associated with primary glomerulopathies, which can lead to chronic kidney disease. This is a recognised tendency rather than a proven one, and how this passes down is not settled. Unlike stone formation, which often presents with sudden symptoms, kidney disease can be more subtle. You may notice your dog drinking more water than usual, urinating more frequently, or experiencing a decrease in appetite and weight loss. Your vet will use blood work to check kidney values and urine protein levels to assess how well the kidneys are filtering waste. Regular check-ups are the best way to detect early changes in kidney function.
