Hypothyroidism affects up to 0.2% of dogs causing lethargy, weight gain, and skin problems. Daily medication effectively restores quality of life with minimal welfare costs.
Hypothyroidism welfare is a straightforward welfare improvement story - dogs with this condition suffer from chronic fatigue, weight gain, and poor coat condition that resolves rapidly with appropriate treatment. The challenge is recognition, as early signs are subtle. Regular thyroid screening in predisposed breeds enables early detection and treatment before welfare decline is severe.
