Objective: To carry out an update on equines hypothyroidism. Material and Methods: Available literature from the last 50 years included in the BBCS-LILACS, Fuente Académica, IB-PsycINFO, IB-SSCI, IB-SciELO, Scopus and Scirus, data base as well as historical articles, texts and references cited in work published to date were analyzed. Results: Important information related to the objectives proposed in the present review were found and analyzed. It was then divided in seven sections as follows: etiology, clinical signs, diagnosis, factors which alter the diagnostic tests, no thyroid disease syndrome, prevention and treatment. Conclusion: Hypothyroidism is one of the most common alterations in equines; clinical signs are very characteristic including lethargy, failure to thrive, debility and lack of coordination problems. The most exact diagnostic method is serum measurement of T4L concentration per dialysis. Levothyroxine sodium continues to be the ideal treatment for equine hypothyroidism.
