All horses may be affected by enterolithiasis but certain breeds are predisposed including Arabians, Morgans and Miniature horses. Females are more likely to develop enteroliths than males; this is hypothesised to be due to the presence of prostaglandins in the serum leading to alterations in gut motility. Thoroughbreds appear to be underrepresented. Middle aged horses are most affected with enterolithiasis in horses less than four years of age rarely reported. | All horses may be affected by enterolithiasis but certain breeds are predisposed including Arabians, Morgans and Miniature horses.
