Companion Dog Hypothyroidism Management

Management of hypothyroidism in dogs, a common endocrine disorder causing obesity and lethargy.

Key Facts

Hypothyroidism results from reduced thyroid hormone production in middle-aged dogs
Signs include weight gain, lethargy, cold intolerance, and skin and coat changes
Levothyroxine replacement therapy is effective and affordable for most dogs
Regular monitoring of thyroid hormone levels guides dose adjustment
Breeds including Golden Retrievers and Dobermanns have elevated genetic risk

Welfare Considerations

Untreated hypothyroidism causes progressive welfare decline through metabolic changes, while appropriate levothyroxine treatment restores normal function and quality of life.

What You Can Do

Have dogs with unexplained weight gain or lethargy tested for hypothyroidism
Administer levothyroxine at the same time each day for consistent hormone levels
Schedule regular thyroid monitoring appointments with your veterinarian
