Attack Dogs

The Attack Dogs killstreak reward is unlocked by spending 6000 COD points.
If you have selected to use the Attack Dogs killstreak reward then you will gain it when you have killed 11 enemies without dying.
When you have selected to use the Attack Dogs killstreak reward the Attack Dogs will automatically be released and start hunting down your enemies.
The Attack Dogs killstreak rewards will last for around 30 seconds. The Attack Dogs only need to bite the enemy once and the enemy will be dead so they are rightly so one of the best killstreak rewards in the game and well worth using if you can get the 11 kills in a row without dying.
