A single report of skin disease associated with a functional thyroid carcinoma in a dog

: A 12-year-old neutered male Siberian husky dog was evaluated for alopecia, pyoderma, and diarrhoea suspected to be associated with a functional thyroid carcinoma. Treatment which included a thyroidectomy and subsequent thyroid supplementation led to the resolution of all associated clinical signs. There has been no recurrence of alopecia, pyoderma, or gastrointestinal abnormalities after one year of thyroid supplementation and post thyroidectomy. To the best of the authors’ knowledge, this is the first report of a functional thyroid tumour in a dog associated with hair coat, skin, and gastrointestinal abnormalities.
