Description
Rebecca Saunders and Lipi Buch published a veterinary case report in 2025 about a seriously ill spaniel. The six-year-old dog had suffered collapsing episodes for two months. It also ate poorly, tired easily, and looked lethargic. Scans showed a severely enlarged, weak heart.
Blood work pointed to an underactive thyroid gland. A heart monitor recorded the dog during a collapse at discharge. The dog stopped breathing, and resuscitation restored it quickly. The monitor showed a steady rhythm, ruling out a rhythm cause. Treatment combined heart medicines with thyroid hormone replacement. Doses were tuned at later rechecks. The case shows thyroid crisis can mimic primary heart disease, yet prove reversible.
