Security Dogs

Security Dogs are enemies in Call of Duty: Advanced Warfare in Exo Zombies.

Description
As suggested by their name, as well as being mentioned by Decker, they are likely dogs that were used by the security and were zombified.

Security Dogs, like Hellhounds, appear during special rounds (the announcer will say it in the beginning of the round). The dogs will come out windows and attack the players. When the last one is killed, it will drop a Full Reload power-up.

Dogs can spawn either as regular ones, or as special ones that behave like EMZs and whose attacks will disable the player's exo. There is also a type of dogs that explode when close to a player, similar to a type of zombie on the map.

While rather weak opponents, they deal the same damage per attack as regular zombies and are faster, which can make them sometimes dangerous, especially the EMZ ones.
