After starting his career with Germany’s Helen Langehanenberg, Suppenkasper, a.k.a. Mopsie, joined U.S. dressage athlete Steffen Peters’s stable in 2018 and has been one of the country’s top dressage horses ever since. The pair started strong, winning every Grand Prix, Grand Prix Special, and Grand Prix Freestyle across four weeks of the West Coast Dressage Festival in the winter of 2018 before traveling to Europe for the summer. Among the highlights of that tour were wins in the Leudelange CDI4* Grand Prix and Grand Prix Special in Luxembourg and top-five finishes in the CDI4* at CHIO Aachen. The pair were then named to The Dutta Corp. U.S. Dressage Team for the FEI World Equestrian Games™ Tryon 2018 and helped earn team silver.

Mopsie and Peters were back to their winning ways in 2019, taking first place in the Grand Prix and Grand Prix Special at the Adequan® West Coast Dressage Festival I CDI3* and again in the Grand Prix at AWCDF III CDI3*. They were part of the bronze medal-winning team that summer at the FEI Dressage Nations Cup Germany CDIO5* at Aachen.

In 2020, they were undefeated through the Adequan® Global Dressage Festival in Wellington, Fla., and the CDI3* at Desert Dressage in Thermal, Calif.

The pair kicked off 2021 in the same fashion, winning every class they entered at AGDF, including the Grand Prix and Grand Prix Special CDI4* during AGDF 3 and the Grand Prix and  FEI Grand Prix Special CDI5* during AGDF 7.

Mopsie and Peters were part of the silver medal-winning U.S. Dressage Team at the Tokyo 2020 Olympic Games, where they also placed in the top 10 in the Grand Prix Special and Grand Prix Freestyle to Music. Their lively freestyle to a medley of electronic dance music brought them a new level of fame to mainstream audiences, with Mopsie earning the moniker “Rave Horse” after being featured in a viral TikTok.

In 2022, Mopsie and Peters represented the U.S. at the FEI Dressage Nations Cup Germany CDIO5* at CHIO Aachen, then went on to win the Kronberg CDI4* Grand Prix and Grand Prix Freestyle in July. Mopsie and Peters again represented the U.S. at the ECCO FEI World Championships in Herning, Denmark.
