What Gene Causes Stone Formation in Dalmatians?

Updated: Aug 16, 2023

Dalmatians are a unique breed of dog, known for their striking coat pattern and their susceptibility to developing bladder stones. In this blog, we will briefly discuss the gene that makes Dalmatians prone to stones and the factors that contribute to urate crystals.


The gene that makes Dalmatians prone to bladder stones is the SLC2A9 gene, which is responsible for the production of a protein called URAT1. URAT1 plays a crucial role in the excretion of uric acid, a waste product that is normally filtered out of the blood by the kidneys and eliminated from the body in the urine. In Dalmatians, a mutation in the SLC2A9 gene results in a deficiency of URAT1, which impairs the body's ability to excrete uric acid. This leads to the formation of urate crystals, which can accumulate in the bladder and form stones over time.



While the SLC2A9 gene mutation is a major factor in Dalmatians' susceptibility to bladder stones, it is not the only one. Other factors that contribute to this condition include diet, hydration, and exercise. Dalmatians require a diet that is low in purines, which are compounds found in some foods that can increase uric acid production. They also require adequate hydration to help flush out uric acid and prevent the formation of crystals. Exercise is also important for Dalmatians, as it can help promote healthy blood flow and prevent the accumulation of urate crystals.


There are several ways to manage bladder stones in Dalmatians, including dietary changes, increased hydration, and medications that help dissolve the stones. In severe cases, surgery may be necessary to remove the stones. It is important for Dalmatian owners to work closely with their veterinarian to monitor their dog's urinary health and take preventative measures to minimize the risk of bladder stones.



In conclusion, the SLC2A9 gene mutation is the primary factor that makes Dalmatians prone to bladder stones. While there is no cure for this condition, it can be managed through dietary changes, increased hydration, and medications. Dalmatian owners should work closely with their veterinarian to monitor their dog's urinary health and take proactive steps to prevent the formation of bladder stones. With proper care and management, Dalmatians can lead healthy and happy lives despite their susceptibility to this condition.
