[header] How to care for an arabian horse [title] Provide a large pasture. [step] Because of their high intelligence, arabian horses require a large pasture to roam and forage in. Use metal or wooden fencing that is at least 5 feet (1.5 m) tall to keep your horse in the pasture. 
Avoid using barbwire or any other high tensile wire fencing. These can cause serious injury to your horse if they get their legs caught.
