Oxalate nephropathy in a Tibetan spaniel litter. A probable case of primary hyperoxaluria.

ABSTRACT

Severe oxalate nephropathy with end-stage kidney lesions was found in two pups of a litter of three Tibetan Spaniels. This histopathological finding strongly suggests a primary hyperoxaluria since there was no exposure to agents capable of producing secondary hyperoxaluria. Primary hyperoxaluria has not been reported as a spontaneous disease in the dog, although it is a well-known, but rare, inherited metabolic disease of man.
