Patrick is first seen on a cattle drive with other horses. Rico chooses Patrick as his new replacement horse after riding Buck to the cattle drive. Rico claims Buck to be too "skittish," so he selects Patrick to assist him on his "mission" instead, much to Buck's grief. Sometime later, Buck finds Patrick guarding his post at Echo Mine. He manages to trick Patrick into leaving his post by warning him about Rico. He tells Patrick that Rico will break out the horse whip when he's finished with his task, and he wasn't shy about using it. Taking Buck's advice, Patrick runs away to avoid Rico. Buck then gloats and says, "He must be taking stupid lessons from that buffalo."
