Primary hypoparathyroidism is an uncommon endocrinopathy in dogs, resulting from absolute or relative deficiency in the secretion of parathormone (PTH). The dog presented signs of hypocalcemia, including muscular spasms, tetany and cramps, evolving to tonic-clonic seizures and fever. Emergency therapy for hypocalcemia included glucose physiological solution at 0.45% and calcium gluconate administered intravenously. Diagnosis was confirmed by the presence of hypocalcemia, hyperphosphatemia and a decrease in parathormone (PTH).
