Rainbow Dog

The Rainbow Dog is a Field Order reward created by RisingSun2013.

Call of Duty Online 2
The Rainbow Dog appears in Call of Duty Online 2 as a special Field Order-exclusive reward. It is somewhat a mix of a Guard Dog and attack dogs, since it is only one dog but goes off on its own to attack other players. It has more health than either of the similar streaks mentioned, and get fly across the map to other areas, leaving behind a rainbow for a limited amount of time. In maps without enough space for him to fly, it will be able to run faster instead.

Trivia

 * It is a reference to the t-shirt in the Call of Duty: Modern Warfare 3 map Boardwalk that says "get a 40 killstreak, get a rainbow dog".
