Abstract: Hypothyroidism affecting the metabolism of all organs does not present a pathognomonic symptom that defines and diagnoses the pathology, with confusion or inconsistencies in establishing a definitive diagnosis being common. The aim of this study was to describe a case of hypothyroidism in a mixed-breed dog that was initially misdiagnosed as a fungal disease. A 9-year-old, male, mixed-breed dog with a history of weight gain, lethargy, alopecia (rat tail and hairy fur) and cold intolerance, who at the age of 7 underwent fungicide treatment due to alopecia, developing liver cirrhosis, arrived at the veterinary clinic X with a provisional diagnosis of hypothyroidism. Clinical examination revealed normal body temperature, mucous membrane and heartbeat, rough and brittle coat, irregular alopecia predominantly in the tail region. The hemogram showed an increase in plasma protein (11 g / dL) and biochemical elevation in alkaline phosphatase (165 IU / L) and cholesterol values (275.3 mg / dL). The laboratory diagnosis showed an altered thyroid profile with an increase in the value of Thyroid Stimulating Hormone (TSH - 0.93mg/Ml) and a reduction in free thyroxine (LT4 - 0.3) and total thyroxine (TT4 - 0.4 mg/mL). Based on laboratory diagnosis and clinical symptoms, the case was diagnosed as hypothyroidism. He was treated with Levothyroxine (24 μg / kg body weight) orally. The owner returned for consultation after 57 days of treatments, an improvement was noted after treatment with oral T4 (levothyroxine sodium).
