call of duty: world at war

i've been playing it online on my ps3. it's very addictive...
when someone gets a killing streak, they can call out the dogs to attack the opponents (homing) and omg.. i hate those dogs!! they are just imba!
people shout over the speaker: "fuck! damn those dogs!"
it's really irritating when u've like 3-4 of them coming to you in different directions.
