Patrick is soft-spoken and serious-minded, similar to Rico. He is also very obedient and does whatever he is told. However, he can be quite gullible when told otherwise, especially by another horse.
Patrick is first seen on a cattle drive with other horses. After riding Buck to the cattle drive, Rico selects Patrick as his replacement horse to assist him on his "mission" because from the way he saw Buck's exchange with the cows, he interpreted it as Buck being "skittish around cows," leaving Buck distraught. Sometime later, after Buck had escaped some ranchers who tried to return the stallion, he 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."
