Breeders’ attitudes toward horses with the congenital throat malady that leads to partial paralysis of the larynx have changed markedly since the 19th century.
In 1889, the Duke of Westminster, the owner and breeder of Ormonde, the greatest English racehorse of the 19th century, sold his champion to Argentina after only two seasons at stud because the horse was “a roarer and a descendant of roarers,” and he did not want to contaminate the English Thoroughbred.
