New research highlights dog breeds at most risk of hypothyroidism

A new study from the Royal Veterinary College explores the frequency and risk factors for hypothyroidism in dogs in the UK, promoting greater awareness with earlier detection and treatment. New research the Royal Veterinary College (RVC) has shed light on the dog breeds most predisposed to hypothyroidism, a life-long hormonal disorder caused by a deficiency of thyroid hormones. The findings reveal that breeds, including Standard Doberman Pinschers, Tibetan Terriers and Boxers are highly predisposed to the condition, while some other breeds such as French Bulldogs, Pugs and Yorkshire Terriers are among the breeds least likely to experience hypothyroidism. Hypothyroidism, a commonly diagnosed hormonal disorder in dogs, usually occurs due to a deficiency in thyroid hormones. The condition can reduce quality of life with affected dogs often showing weight gain, lethargy, hair loss, intolerance to the cold and a tragic facial expression. Previous research has identified several potential risk factors for hypothyroidism such as breed, neutering and aging. However, much of this earlier work is now dated, meaning risk factors need to be checked again for relevance to the current UK dog population.
