Breed: German Sport Horse (DPS/RPSI)
Missing Color or Outcross Information: Outcross / British Sport Horse
Any other info: I checked this site and there is 'Sport Horse Breeding of Great Britain (SHBGB)' listed as member of WBFSH
This is represented by the British Warmblood on Equus. British Sporthorses on Equus are only required to be 1/4th Warmblood and do not qualify for WBFSH breeding.
