They sang “Happy Birthday” to JD the horse, but never imagined what happened next! JD is a grandson of the greatest racehorse of all time, Secretariat, the Triple Crown Winner, with one key difference – JD is quite slow! Good thing he has other great qualities. The cake is a horsey “Birthneigh” cake (and no, JD didn’t eat the candles, but loved every bite!). Share this on Facebook if you’ve ever sang Happy Birthday to a horse!
