Guard Dog

Guard Dog is a pointstreak available in Call of Duty: Ghosts. When activated, Riley will teleport onto the map, and follow the player similarly to the AH-6 Overwatch. He has slightly more health than a regular player. When Riley is near enemies, he will growl or bark, notifying the player. Riley will also attack enemy players if they get too close to him.

Trivia

 * When player calls in the Guard Dog, instead pressing a button on a small touchscreen, player will perform a whistling animation.
