overall, and McDonald was dubbed "First Lady of American Dressage." Brentina was named the 2005 Farnam/Platform USEF Horse of the Year. After the 2008 Olympics, where the mare had an uncharacteristically poor performance, she was retired to the Thomas' farm. While McDonald went on to compete with other horses, Brentina developed an impaction in early 2009 and underwent colic surgery to remove a fecalith from her small colon. She has since recovered and attended a retirement ceremony at the 2009 FEI World Cup Dressage Finals in Las Vegas. On January 22, 2010 McDonald was named the U.S. Equestrian Federation's Developing Dressage Coach, a role designed to identify and cultivate future US Dressage stars.
