A 3 yr old, spayed, female miniature mchnauzer was presented for rhythmic, spontaneous contractions of the abdominal wall and across the costal arches. The rate of contractions coincided with the heart rate and increased during exercise. The dog was diagnosed with primary hypoparathyroidism based on low plasma ionized calcium and serum parathyroid hormone (PTH) concentrations. Fluoroscopic exam confirmed the diagnosis of a synchronous diaphragmatic flutter. Treatment of the hypocalcemia led to resolution of the diaphragmatic flutter.
