I don't know how many actual ribs they have, but they have 10 pairs of false ribs.
a horse has 18 pairs of ribs where as an arab has 17 pairs
they have 18 ribs, while the Arab has 17 ribs
18, Arabs usually have 17
It might range from 13 to14 but if you look at the skeleton on Google images that can give you an accurate count ^^ wrong in general horses have 18 ribs but Arabian horses have 17 :)
18 pair - according to Cyclopedia Anatomicae by Gyorgy Feher published 1996
