Renal disease was detected in 21 of 56 progeny from a specific line of inbred Norwegian Elkhound (NE) dogs. Results of hematologic and clinical chemistry examinations revealed that minor differences existed between affected and nonaffected NE dogs. Of 21 NE dogs with renal disease, 3 had persistent glucosuria without hyperglycemia. The 21 affected dogs had impaired ability to concentrate urine. According to renal function tests, glomerular filtration rate of normal NE dogs was less than that of normal mixed breed dogs. Although a few affected NE dogs excreted large amounts of amino acids in urine, statistically significant differences did not exist between normal and affected NE dogs with regard to alpha-amino acid nitrogen content of their plasma or urine. By paper chromatographic separation techniques, free amino acids of plasma, urine, and extracts of liver and kidney were not qualitatively different for mixed breed dogs, normal NE, and NE with renal disease. Statistically significant differences were not detected between serum calcium concentrations of normal and affected NE dogs. In NE dogs with renal disease, there was significant hypercalciuria, but a few normal dogs excreted more than did some dogs with disease. Blood pressure values of normal mixed breed dogs and affected NE dogs were similar. It was concluded that hematologic and blood chemical abnormalities, derangement of amino acid or calcium metabolism, and hypertension were not associated with renal disease in these NE dogs.
