Horseland S03 E01 The Secret

When a new boy, Chase, visits Sarah at Horseland, the other riders think that he's her boyfriend. They soon discover, though, that Chase is Sarah's cousin. He helps them prepare for an upcoming dressage show, but refuses to read direction. Chloe and Zoey think that he is illiterate, but it is revealed that he is, instead, dyslexic, as is Will.
