HIPOTIREOIDISMO EM CÃES: relato de caso

Abstract

Hypothyroidism is an endocrine disease of great importance in small animal clinics, being more

common in dogs and rare in cats. Hypothyroidism is a deficiency in some part of the hypothalamic- pituitary-thyroid axis that leads to low concentrations of T3 and T4 hormones in the body. It affects

middle-aged and mostly purebred dogs. Its clinical signs are varied and non-pathognomonic, with dermatopathies and metabolic disorders being more common. Diagnosis is made by of the set information obtained from the anamnesis, history and clinical examination associated with laboratory tests of hormone dosage. Treatment is done with optimal hormone replacement in the right dosage to obtain a good clinical result. The prognosis varies depending on the response to treatment. The objective of this work is to gather a literature on hypothyroidism in dogs in order to bring information about this pathology, which is so common in small animal clinics, but so often neglected or misdiagnosed, and to report a case seen in a veterinary clinic, showing all the procedures performed and the conduct taken upon the diagnosis of hypothyroidism.
