They are crossbred with lighter horses by breeders of heavy hunters in order to increase size and improve disposition.[1] Purebred Percherons are also ridden, and some have proven useful at show jumping.[2] Crossbred Percherons have been used successfully in dressage.[55] In both the Falkland Islands and northern Australia, Percherons have been crossed with local mares, primarily Criollos in the Falklands, to produce larger stock horses with greater stamina. These crossbred horses are used extensively in both the sub-Antarctic climate of the Falklands and the sub-tropical climate of Australia for working stock.
