Details
Hyperuricosuria (HUU) describes elevated levels of uric acid in the urine causing the formation of calculi (stones) in the urinary tract. These stones form in the bladders or sometimes kidneys, requiring surgical removal, and can be difficult to treat. HUU can occur in any breed but is most commonly associated with the Dalmatian, as Dalmatians are homozygous for HUU (HU/HU). Outcrossing programs have introduced ?low uric acid? dogs, derived from Dalmatian x Pointer backcrosses, into the purebred gene pool, providing a means for breeders to reduce incidence of the disease and maintain the breed characteristics. This mutation is not the sole cause of urate bladder stones in dogs, so may not account for other causes of stones, such as liver disease and diet.

Current best evidence, supported by peer-reviewed research in related breeds, indicates that the use of this test is likely to be relevant in the breed. Clinical cases, associated with affected genetic test results for this mutation have been described in more than one country. The test has been in use, with positive results, by breeder in the UK since 2010. Screening is part of UK testing practices in the UK since 2017.
