Riley (Ghosts)

Riley is a playable dog character in Call of Duty: Ghosts. He is a member of the Ghosts squadron; Riley is part of the player's team and works as a friendly character who will help and support the player by "sniffing out explosives and assisting the player against hostiles". He is also able to take down helicopters by jumping up when they fly close and biting the pilot and then landing them shortly after taking out the pilot. He incurred a non-lethal bullet wound to his left thigh in Sin City, and survived by Logan loading him into a helicopter at the end of the mission. Although healed, Riley is last seen in the prologue of All or Nothing.
