Adalmation presents with difficulty urinating. bladder stones are confirmed with the ultrasound and a cystotomy is performed. which crystal is commonly observed in the dalmatian and not expected to be seen in other dog breeds?

ammonium urate stones

Explanation:

There are many Dalmatians that have a genetic disease called Hyperuricosuria (Huu). Due to a faulty gene in the DNA of the Dalmatian the uric acid in the body is not broken down by the liver.

The excess amount of uric acid in the blood causes the formation of ammonium urate stones.

Dalmatians affected by Hyperuricosuria have 400-600 mg/24 hours of uric acid in their bodies compared to 10-20 mg/24 hours in other dogs.
