Hypothyroidism is one of the most common hormonal disorders in dogs, causing a wide range of symptoms that can significantly impact quality of life if unrecognised.
Hypothyroid dogs often suffer for months or years before diagnosis because their symptoms are subtle and owners and sometimes vets attribute them to ageing. Dogs with uncontrolled hypothyroidism experience chronic fatigue, discomfort from skin conditions, and the misery of poorly regulated body temperature. The condition is completely manageable with inexpensive daily medication once diagnosed, making delayed diagnosis a preventable welfare failure. Dogs on appropriate treatment typically transform dramatically in activity, coat quality and apparent happiness.
