Guilder is one of the hunting dogs owned by Ninomiya. He lives together with Joe, Bomb, Jack and Kōshirō. One day in the forest, Guilder meets Joe's brother Weed along with the rest of his pack mates. Together they scare of a bear threatening to kill them. Later, Guilder and his pack mates are out to find a bear that has attacked a human. As they climb a rocky ledge of a mountain, they are bombarded with rocks. The bear (Hybrid Grizzly Bear) is waiting on top of a cliff, pushing rocks down at them. His leader, Joe, is seriously wounded by the bear. See more pictures in Guilder (Photo Gallery).
