Lusitanos names follow a naming scheme. The first letter of the horse name correlates to the year of birth. Letters not used are K, W and Y.

Breeders must honor this naming convention when naming their Lusitanos. If this is not done, APSL will insert the current year's letter followed by a hyphen at the beginning of the name of the horse, thus becoming part of the horse's official name.
