Andy is Hidetoshi's new hunting dog and the nephew of John. He appeared in GDW:O and in TLW.

In GDW:O, Andy first appears when Rigel and Kotetsu stumble into Hidetoshi's garage, where he is in his kennel. At first, Andy is suspicious of the two but lets them go. Rigel and Kotetsu stay with Daisuke for a while, travelling up to the mountains with Andy. When Gin and the others are released, Gin sees John inside the pup and thanks him for helping his son. Andy retreats from Gin at first, but soon travels up to the mountains in search of the Ouu army. He finds Rigel after stealing a bird from him and is welcomed into the Ouu army. Whilst travelling, Andy runs into Masamune and gives him a warning to leave the mountain, but the evil dog gives him the deaf ear and attacks him. Andy manages to escape after a close call. Later on, Andy and the other puppies find Masamune climbing the cliff to reach the Ouu army by surprise. Andy leaps down to attack him, but is thrown off. Rocket jumps down and manages to catch him, but the two dogs fall into the river below. However, because of Rocket followers, he survives and is safely carried to shore.

In TLW, When Sasuke arrives at the Akame Mountains to meet Orion and his brothers, a young adult Andy greets them along with Bon and Yamabiko.
