What horse breeds have been influenced by the Andalusian?
There is hardly a horse breed out there without some influence of Iberian blood. The popular Warmblood breeds were largely influenced by an infusion of Spanish blood to transform ordinary coach horses into sport horses. Welsh, Connemara ponies, and Irish Draught horses all have a strong Iberian background. Iberian blood was used to improve early European race horses that were the foundation for the thoroughbred of today. The original horses brought to the Americas by the Conquistadors were Iberians. They were the basis of our American stock from which all American breeds were in some part derived. This means that Iberian blood had a strong influence on Quarter Horses, Mustangs, Morgans, Rocky Mountain Horses, and all of the gaited breeds.
