Concurrent central diabetes insipidus and panhypopituitarism in a German shepherd dog.

This report describes a German shepherd dog that was presented with proportionate dwarfism and coat changes typical of hypopituitarism but that was also profoundly polydipsic and polyuric. Investigations established a diagnosis of concurrent central diabetes insipidus. Treatment with desmopressin was successful in managing the polyuria and polydipsia.
