Mendoza takes over the reins of Swiss young rider, Morgane Dassio. Horst Van de Mispelaere was bred by Joris and Mia Vermeulen, Belgium. Before Morgane Dassio competed the stallion it was Belgium's Koen Vereecke who jumped the horse to a silver medal at the Belgian Championships for 7-year-old horses.
Horst is the halfbrother of Bisquet Balou C and was earlier this year sold to Morgane Dassio. It is now Dassio's trainer, Mendoza who competed the stallion. In September Dassio and Horst won the junior Championships in Switzerland.
