The dentition of 170 Arab horses of known ages was examined and compar
ed with the dental characteristics of trotter horses and Belgian draft
horses of the same ages. The results indicated that inaccuracies in t
he determination of the age of horses by their dentition may result, a
t least partly, from differences between the breeds of horse involved
because there were some major differences between the three breeds exa
mined. These differences increased as the horses' true age increased,
In general, the rate of dental wear was slower in the Arab horses than
in trotter horses and Belgian draft horses.
