The reigning world champion, Germany’s Isabell Werth, was one of three grand prix riders eliminated under blood rules at CHIO Aachen last week.

Isabell and her current top ride, the 12-year-old Qatarback stallion DSP Quantaz, were eliminated in the CDIO5* grand prix special after blood was spotted in the horse’s mouth partway through their test. The pair had just begun their line of two-tempi changes and were trending around the 74% mark, when the judge at C, Denmark’s Susanne Baarup rang the bell to call them to a halt. She wiped the stallion’s mouth with a tissue, which showed the presence of blood.
