As a two-year-old, Dance Smartly won three of five races, including the Natalma Stakes, and finished third in the Breeders' Cup Juvenile Fillies. She won the Sovereign Award for Canadian champion two-year-old filly. At age three, she developed into one of the top Thoroughbreds in North America, going undefeated in the 1991 racing season. In her first two starts of the year, she was ridden by Brian Swatuk to easy victories in the Star Shoot and Selene Stakes. In the remainder of her three-year-old campaign, she was ridden by American Hall of Fame jockey Pat Day. Her victory in the Canadian Oaks, Canada's most important race for three-year-old fillies, was so dominant that her owner decided to race her next against the colts. Dance Smartly became the second filly to capture the Canadian Triple Crown by winning the Queen's Plate, the Prince of Wales Stakes, and the Breeders' Stakes by a combined eighteen lengths. She next won the Molson Export Million, earning her first graded stakes victory as her previous races had been restricted to Canadian-bred horses. Preparing for the Breeders' Cup Distaff at Churchill Downs, Dance Smartly started favouring her front hoof and missed several weeks of training. Despite coming into the race with only one workout in six weeks, she won easily, defeating champion older mare Queena and Versailles Treaty. Track announcer Tom Durkin called her "undefeated this year, and the undisputed queen of racing on this continent." For her 1991 performances, Dance Smartly was voted the Eclipse Award as North America's best three-year-old filly plus two Sovereign Awards as Canada's best three-year-old filly and the Horse of the Year. Despite being hampered by an injury to the suspensory ligament of her right foreleg, Dance Smartly raced four more times at age four, winning once against colts in the Canadian Maturity Stakes. She also finished second by a nose in the King Edward Cup Handicap and third in the Grade I Beverly D. She then retired as the number one money-winning filly in the world, having won on both turf and dirt, and at distances of up to miles.
Stud record
As a broodmare at Sam-Son Farm, Dance Smartly produced a number of top horses, including the back-to-back Queen's Plate winners Scatter the Gold and Dancethruthedawn, both by Mr. Prospector. She was named the 2001 Canadian Broodmare of the Year. Dance Smartly was euthanized in August 2007 after suffering an irreparable injury related to an arthritic stifle in her paddock at Sam-Son Farm. She was 19 years old and not in foal at the time. "Dance Smartly was a once in a lifetime horse," said Tammy Samuel-Balaz, the daughter of Dance Smartly's owner. "She was magic and gave us incredible thrills as both a racehorse and a broodmare. While we were fortunate enough to have bred and owned her, she was truly Canada's horse."
Dance Smartly was by Danzig, the leading sire in North America from 1991 to 1993. Her dam was Classy 'n Smart, who won the Canadian Oaks and was named the Canadian champion three-year-old in 1984. Classy 'n Smart produced several other stakes winners including Smart Strike, a grade I winner and two-time leading sire in North America. Dance Smartly's second dam No Class was the foundation mare of Sam-Son Farms, producing six stakes winners and four champions including Sky Classic. No Class, Classy 'n Smart and Dance Smartly were each named Canadian Broodmare of the Year.
