Gladiola is a generous, miniature, pink poodle. He ran away from his home before the events of The Lightning Thief but was later found and returned to his owner by Grover Underwood.

Percy Jackson and the OlympiansEdit

The Lightning ThiefEdit

At first, Percy refused to say hello to the dog, but eventually agreed as Gladiola was their ticket West. When Grover found him and talked to him, he told him about the $200 reward if he was found and returned, and agreed to be returned so Percy's group could use the reward to buy train tickets to go West. The dog is considered generous because he didn't like his home and ran away, but was willing to go back to help Grover, Percy, and Annabeth.
