Yes, Spanish cattle thrived remarkably well in parts of North America where bears, wolves, and other large predators were heavily present. Descendants of these early arrivals—such as the Texas Longhorn and Florida Cracker cattle—grew into massive, feral or semi-feral populations across the open range.

How Spanish Cattle Survived Predators
Natural Selection: Harsh environments and constant pressure from wolves, coyotes, and bears weeded out weak animals quickly.
Defensive Horns: Unlike modern beef breeds, Spanish cattle developed exceptionally sharp horns. Both cows and bulls used these horns aggressively to protect vulnerable calves.
Herd Behavior: Cows learned to bunch together and aggressively mob or charge predators rather than flee in a disorganized panic.
Hardiness: They possessed high stamina, could travel long distances without water, and foraged effectively on rough brush.

Regional Success Despite Predators
Texas and the Southwest: Brought north by Spanish missions and explorers, thousands of head roamed freely. Despite dense populations of wolves and bears, they multiplied exponentially into the millions by the 19th century.

Florida: Released by early conquistadors, Andalusian stock adapted to swamps and scrubland filled with panthers, bears, and wolves, establishing a permanent wild and domestic cattle culture.
