Well, You may be wondering how people get such high kill streaks! Surely they know something you don’t! Not really, they just planned it very well and added a bit of skill with a tiny bit of luck!
In Call of Duty World at War there are bonuses for getting kill streaks up to 7. However it will record your max kill streak (without dying of course). This however is only for bragging rights! Most people easily get 15-20 kill streaks, simple. Get yourself to 7 and get dogs then get lucky and not die while they are killing everyone! Good job, however you will never pass 20 kills in a row relying on dogs!
