A control of a golden retriever with renal dysplasia.

A six-month-old male Golden Retriever with a three-month history of polyuria and polydipsia was examined. Hematological examinations revealed nonregenerative anemia, azotemia, high serum creatinine level, hypercalcemia, hyperphosphatemia, hypercholesterolemia, hyperamylasemia, and low level of total serum protein. Urinalysis indicated mild proteinuria, and low specific gravity. Radiographic and ultrasonographic examinations revealed bilateral small sized kidneys. Histological examination by renal biopsy confirmed the diagnosis of renal dysplasia. Treatment with a dietary protein restriction, oral adsorbents, and dried aluminum hydroxide gel have been performed in this dog, and then, azotemia, high serum creatinine level, hypercalcemia, and hyperphosphatemia were improved. During 10 months after the initiation of treatments, no significant clinical change except polydipsia and polyuria has been observed.
