MGISW Mind Your Biscuits (Posse) has died at the age of 13 in Japan at Shadai Farm.According to a Tuesday report by Japanese media site ZBAT, the horse “had been behaving normally and in good health, but his condition suddenly worsened after breeding in the afternoon of that day, and he passed away.”“I'm shocked that he suddenly passed away,” Yoshida Teruya, the representative of Shadai Farm, told ZBAT. “He was only 13-years-old and still young, and he was producing good offspring, so it's truly regrettable.”Bred in New York by Jumping Jack Racing LLC, Mind Your Biscuits raced from the ages of two until five, earning more than $4,279,000 across 25 starts. His major wins include the GI Malibu Stakes and not one but two victories in the G1 Dubai Golden Shaheen in 2017 and 2018.Upon his retirement from racing in 2018, he was sold to Shadai Farm where he has stood ever since, producing the likes of 2023 GI Breeders' Cup Classic runner up Derma Sotogake. He was named Japan's leading freshman sire in 2022.The post MGISW Mind Your Biscuits Dies In Japan At 13 appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
