Plain-English summary
A 6-month-old miniature Schnauzer was brought to the vet because it was vomiting, had diarrhea, wasn't eating, and seemed very tired. The dog also wasn't drinking water on its own, which led to high sodium levels in its blood (hypernatremia). The vet treated the dog with fluids, which helped resolve the symptoms. Further tests ruled out other conditions, and it was determined that the dog had a congenital brain malformation affecting its ability to sense thirst.

Abstract
A 6-month-old miniature Schnauzer presented with hypernatremia and clinical signs of vomiting, diarrhea, inappetence, and lethargy. The dog did not consume water on its own. Hypernatremia and the related clinical signs were resolved by fluid administration. Endocrinological investigations and urinalysis excluded the possibility of diabetes insipidus and hyperaldosteronism. Therefore, the dog was diagnosed with hypodipsic hypernatremia. Magnetic resonance imaging revealed dysgenesis of the corpus callosum and other forebrain structures. On the basis of these findings, congenital brain malformation associated with failure of the osmoreceptor system was suspected.
