Canine Hypothyroidism: The Great Mimicker

Dr. Rosemary Stolzer-Bolton, DVM, DVMCaninePre-RACE approval · 0.5–3 CE creditsFree Preview

Hypothyroidism is the most common endocrine disease in dogs and the most frequently misattributed to 'normal aging.' This course follows Moose, an 8-year-old Golden Retriever, through the complete diagnostic workup — including the thyroid testing minefield, sick euthyroid syndrome, and drug confounders — through levothyroxine dosing, monitoring protocols, and the complications that emerge when the diagnosis is missed. Integrative adjuncts including selenium, omega-3s, and acupuncture are evaluated with honest evidence levels.

Learning Objectives

  • 1Identify the classic clinical presentation of canine hypothyroidism including the dermatologic, metabolic, cardiac, and neurologic manifestations that distinguish it from normal aging
  • 2Interpret a complete thyroid panel (total T4, free T4 by equilibrium dialysis, TSH, TgAA) and recognize the limitations of each individual test including sick euthyroid syndrome and drug-induced T4 suppression
  • 3Calculate and prescribe levothyroxine at the correct starting dose, specify the appropriate blood draw timing for monitoring, and adjust the dose using a structured 25-50% increment protocol
  • 4Recognize and manage hypothyroid complications including myxedema coma, hypothyroid peripheral neuropathy, and drug-induced hypothyroidism from sulfonamides and phenobarbital
  • 5Evaluate the evidence for integrative adjuncts — selenium, zinc, omega-3 fatty acids, probiotics, and acupuncture — and counsel clients accurately on their role as adjuncts to levothyroxine therapy
