Plain-English summary
A 6-year-old male Chihuahua was brought in because he was having trouble walking and was experiencing seizures. This followed a recent diagnosis of low sodium levels (hyponatremia) and treatment for adrenal gland issues (hypoadrenocorticism). The rapid correction of his sodium levels likely caused a condition called osmotic demyelination syndrome, leading to his neurological symptoms. After receiving anti-seizure medication and supplements, the dog improved significantly, with no seizures or walking problems after two weeks. He remained healthy and free of symptoms for 19 months after treatment.

Abstract
A 6-year-old castrated male Chihuahua dog was presented with hindlimb paresis and ataxia. The dog had hyponatremia and was diagnosed as hypoadrenocorticism 10 days before its visit, and the neurologic signs including generalized tonic seizures and hindlimb paresis occurred 3 days after correction of hyponatremia at a referral hospital. Based on history and clinical findings, osmotic demyelination syndrome (ODS) secondary to rapid correction of hyponatremia was highly suspected. After administration of anti-convulsant and supplements, seizures did not occur, and gait was normalized within 2 weeks. Phenobarbital was tapered and finally discontinued after 3 months, and seizure did not recur. The neurologic signs were completely resolved and the dog continued to be free of neurologic or additional clinical signs over the 19-month follow-up period. ODS should be included among the differential diagnoses in case of any acute neurological dysfunction that occurs with episodes of rapid correction of hyponatremia. To the author's knowledge, this is the rare case report of a dog with hypoadrenocorticism and presumed ODS after rapid correction of hyponatremia leading to neurologic signs including seizures and ataxia.
