Attack Dogs (killstreak)

"Pooch doesn't look too friendly."

- Captain MacMillan in "All Ghillied Up".

In the Call of Duty Series, Dogs are featured in four games:
 * Call of Duty 4: Modern Warfare
 * Call of Duty: World at War
 * Call of Duty: Modern Warfare 2
 * Call of Duty: Black Ops

Hellhounds, a variant of the dog, appear in Zombie Mode.

Single Player
In Call of Duty 4: Modern Warfare, Modern Warfare 2, and Call of Duty: Black Ops dogs jump on the player and knock them down. In Call of Duty: World at War, they jump and bite at the player and can also knock the player down. Like a Banzai charger, the player can kill them before they kill the player by pressing the melee button to break their neck at the right time. They're easy to hear and spot by their growling. If the player breaks the dog's neck at the right time and survives the attack on the Xbox 360 version of Call of Duty 4: Modern Warfare, they will get the "Down Boy" achievement. Dogs in single player mode will only appear as German Shepherds.

Call of Duty: World at War
In Call of Duty: World at War multiplayer, dogs can be called in by a player as a 7-killstreak. The dogs spawn and attack enemy players on the map for 60 seconds. Friendly dogs appear as German Shepherds and enemy dogs are Black Belgian Malinois.

The dogs can be killed, but will continue to respawn until the 60 second cycle has ended. By default, dogs have 100 health. Dogs attack by lunging and biting at enemy players. In core modes, players with more than 90 health points can survive up to 2 dog lunges before dying in Regular modes, but in Hardcore players die instantly even with Juggernaut. Killing a dog will give a player 3 XP depending on the game mode, but will not count as a kill or an assist. However, in Team Deathmatch and Free-for-All players score 3 and 2 points respectively, making it possible to actually win the game with fewer kills than would otherwise be necessary. For this reason, it can actually be detrimental to call in Dogs in these gametypes. Dogs rarely go into water and cannot climb ladders. Dogs also cannot attack players in tanks. Some consider this killstreak to be superior to the helicopter in Call of Duty 4 due to the fact that it can attack anywhere (with the exception of water).

Call of Duty: Black Ops
The attack dogs make a return in Call of Duty: Black Ops, and have been upgraded to an 11-killstreak reward in Multiplayer. German Shepherds (friendly) or Belgian Shepherds (enemy) will spawn for a set period of time after activation. The initial spawn will be four dogs, with four reserve dogs. As the first four are killed, they are replaced from the reserves, giving a maximum of eight dogs over the time the kill streak is active (one minute). The dogs can now kill in one bite, due to the challenging task of acquiring 11 kills. Dogs are also attracted to gunfire, so a good thing to keep in mind would be to try and leave things quiet for a while. Ghost Pro does not make the player invisible to them, nor does any other perk. The only effective ways to counter dogs are to camp in an area with long range sight-lines and preferably with a wall behind the player in order to be able to gun them down, there is another way to counter dogs is with attack helicopter as it will open fire on enemy dogs if there is no enemy in preferable range. Always be careful near low walls or gates at the edge of the map, as this is where the dogs enter the map. Dogs are often favored over the gunship as they cannot be shot down, can seek out enemies (even ghost pro users) and kill in one bite

Call of Duty 4: Modern Warfare
It is not automatic, but many, many dogs will attack the player. They will constantly attack the player, following him through the school and to the hotel. Even if the player survives the attacks, Captain MacMillan will most likely be killed. It is possible for the player and Captain Macmillan to survive, though this is very difficult. You can do this by running with your sidearm through the school and running to the next checkpoint, it seems that they cannot go past a certain stage. You have to wait for Macmillan to catch up.
 * In the level, "The Coup", dogs are seen attacking civilians in the city. As most of the other dogs, they are German shepherds. Some are tamed and at their owners' sides, but others are individual and running amok, attacking people. One is seen chasing a man down an alleyway and over a fence.
 * In the level, "Hunted", some dogs are ordered to attack the SAS, after saving Nikolai. One of the squad-mates points out it is very quiet, and then hostiles fire upon them, sending two dogs.
 * In the level, "Safehouse", dogs are often seen alongside their owners. As the humans snipe the SAS, the dogs just charge, easily allowing the team to pick them off.
 * In the level, "All Ghillied Up", dogs are first seen if the player misses the first two contacts. Some hostiles will attack the player, and around five dogs will come through the tall grass. If the player successfully takes them out, however, a dog can be seen sleeping on the couch in the house near where they were standing. Alerting the soldiers in the house or the one by the car, will cause the dog to wake up and attack. This one will awaken if anyone is alerted before reaching the church.There another dog seen where you are out of the junkyard when you are crawling uner the trucks during the convention,at the left,you will see a dog sleeping with its owner. A rabid dog is seen, tearing apart a Russian soldier. The player is supposed to sneak around it. Doing this will only make the dog growl and maybe bark. However, shooting - whether or not the player kills it - will result in failure. After shooting it, a long, mournful howl erupts from the dog's throat. Then a pack of dogs rushes towards the player, overrunning him and then killing him.
 * In part 2 of Captain Price's flash-back, "One Shot, One Kill", several dogs are seen and fought. At the beginning, some are sitting still as Imran Zakhaev unloads the fuel rods, and is sniped by Lieutenant Price. Afterwards, Price and MacMillan must evade wave after wave after wave of enemies, some dogs are seen in the groups. More are seen in pens, as the sniper-team moves through apartments. As the player moves forwards to the extraction point, dogs will randomly pop out, depending on earlier actions. Carry MacMillan up a wall of debris to the second floor of an apartment building. He'll tell the player to set him down. Do so, and clear out the floor. Three dogs will be up here, but are easy to pick off. When the player makes it to the pool building, there are some dogs feasting on a few dead bodies in the emptied deep end of the pool. Sometimes, the dogs will just jump out and flee, killing the two guards, but if left alone they will attack the Ultranationalists that attack the player when he's defending MacMillan at the Ferris wheel. Finally, in the final fight, while trying to defend MacMillan while the helicopter is inbound, some dogs will also attack the player.
 * In the level, "The Sins of the Father", dogs attack Soap MacTavish and Griggs as they pursue Viktor Zakhaev. They are very few and very easy.
 * In the level, "Ultimatum", some dogs will attack if their owners are killed. Also, a dog's head can be seen painted onto some signs in Russian and are posted to chain-link fences.

Call of Duty: World at War

 * Dogs appear in one level, Vendetta. Some Germans are seen walking them at the beginning, and one must be killed, while sniping for Reznov. In order to earn the trophy/achievement "The Professional", by killing the two soldiers by the stairs in one shot, then the two in the middle with one, the two crouched near each other on the left with two (or one - does not matter), then knifing the dog, and finally killing the last man that runs up with the dog (or killing the last soldier and the dog with one bullet, although this can be very tricky) - without reloading.


 * Dogs do not appear in the level Vendetta in the Wii version of World at War, though they are present in multiplayer.

Call of Duty: Modern Warfare 2

 * In the level, "Takedown", a dog leaps at Roach from inside of the chain-linked soccer field. He can be knifed, shot, or left to run outside and attack the player. A few yards ahead, a civilian leans out his window and warns the player of dogs and more soldiers ahead. He is shot, then, and the Militia order dogs to attack Roach, as they fire upon him. At the end, a very faint bark can be heard, as "Soap" tackles Rojas onto the car. After this, dogs are not seen again until "Contingency".
 * In "Contingency", Price says, "Dogs, I hate dogs. These Russian Dogs are pussycats compared to the ones in "Prypiat", remembering his times with MacMillan. Price and Roach have to shoot some dogs as they move towards the town.
 * In "The Enemy Of My Enemy", dogs are seen once again, attacking both Soap and the Shadow Company soldiers. They are rarely seen, and the player can sometimes hear them but not see them.
 * In "Just Like Old Times", at the beginning. Soap and Price have to pick them off, along with two groups of Shadow Company soldiers, before rappelling down towards General Shepherd's cave network.

Call of Duty: Black Ops

 * Dogs appear in the level, WMD, where they are used by Russian troops in the beginning to back-up and find team Kilo-1. However, Team Kilo-1 was able to snipe the dogs out with crossbows, along with their Russian owners. They can also be found along the odd Russian personnel.

Defense against Dogs

 * Tanks are impervious to Dogs and can kill them easily.
 * The Reconnaissance perk allows the player to see the locations of the dogs.
 * Staying in an area where the dogs can only come from one direction makes them easier to deal with.
 * Dogs cannot climb ladders. So finding an area only reachable by ladder is very useful.
 * A common tactic in multiplayer is for players to use bayonets. This will conserve ammo and will instantly kill the dog, and has more range than the knife. Be careful, as many players have died from a missed stab.
 * Dogs will use staircases. Also, in the map "Courtyard", if the player uses the trick to get up above the ground on the two center platforms, dogs can also jump up there. However they cannot get on top of the archway connecting the two. The same goes for all other archways.
 * Bouncing Betties will kill Dogs instantly.
 * Dogs hate water in multiplayer, this makes Makin a good battlefield for avoiding dogs.
 * Be careful about using an unsuppressed weapon when defending against dogs as it will give away the player's position.
 * Dogs cannot reach the player if they stand on a table or other raised surface. They will only look and growl. However, this is not the case in Black Ops, as if the player stands on a raised surface, such as a table, the dog can lunge and kill the player but sometimes you can get away with it.
 * If the player lies down in a corner dogs will not be able to lunge on top of the player and will only be able to bite at the player from one angle making them much easier to deal with.
 * There is a glitch on Outskirts where if the player goes to the top of the church tower and lie down on the floor facing the stairs, the dogs will stand at the floor below him, look up, and bark.
 * On Radiation, a Black Ops map, it is possible to lure the dogs to the conveyor belt where the dogs will become stuck and die.
 * Decoy grenades in Black Ops prove excellent against dogs as they attract and can kill enemy dogs.
 * A great tactic to escape dogs is to go to a higher elevation only accessible via a tall ladder, that way the dogs cannot jump up and kill the player. (A good example is the big comms tower on Array or the little elevated room near point C on Radiation).
 * If the player is proficient with knifing a good strategy is to use the ballistic knife for its increased knife speed.
 * While you are sitting on the bunk bed in the house on Nuketown dogs cannot kill you, but they will run near the bed and jump.

Strategies with Dogs

 * Following dogs is an easy way of locating enemies. But beware, the enemy might see the player first so using a longer ranged weapon, such as a rifle, will allow them to attack distant enemies while they are distracted by the dogs.
 * As noted above, if a player is trying to defend himself from dogs and does not have either a flash hider or suppressor equipped, he will show up on the minimap as a red dot giving away his position. Use this to the player's advantage.
 * Using Attack Dogs with your Chopper Gunner is a good way to protect yourself from being shot down. In large matches like Ground War this is especially helpful. It is extremely difficult to have the time to lock onto an enemy Chopper Gunner while staring up in the air and not to be killed by the dogs. This strategy is especially helpful in locking down the entire enemy team in objective based games like CTF or Demolition in order to score easy round victories.
 * A good way to counter this would be to find a high spot (it does not matter if dogs can reach it), and, with Valkyrie Rockets, jump off and shoot the rockets, allowing you stay safely floating in the air while you shoot down your opponents Chopper Gunner.

Trivia

 * Although realistically dogs cannot climb ladders, they have been known to leap 6-foot high to get on top of objects, such as the grassy-jungle-like walls on "Courtyard" and can even jump the entire ladder on the balcony in "Dome."
 * Dogs can hit and kill the player that called them in, but the player would have to be standing in the way of an enemy, which is extremely unlikely.
 * In Call of Duty 4: Modern Warfare, when dogs jump on NPCs (such as MacMillan), the NPCs will not attempt to break the dogs' necks, but rather shoot them in the side of the head with a pistol.
 * When using the god cheat on the PC version of Modern Warfare, if the player is killed by a dog, their body will dissolve into a pool of blood but they will still be able to move around as a "ghost". Enemies will still shoot at the "ghost".
 * In the Modern Warfare 2 mission "Contingency," Price says "Dogs. I hate dogs." This saying is a reference to Indiana Jones where he says "Snakes. I hate snakes", and also a reference to the many dogs the player encountered in the original Modern Warfare. It could also be a tongue-in-cheek reference to the movie Dog Soldiers, which Kevin McKidd, the voice actor of Soap, starred in.
 * In Modern Warfare 2, it is actually possible to permanently cripple a dog if the player shoots it in a specific part of its leg. This can be done in SHUItContingency where in the beginning the player sees a patrol with a dog and its master in front. Even with its speed reduced to about 10%, it will relentlessly chase after the player, in which case he can either outrun it or put it out of its misery - a direct hit with a thrown stun grenade should finish it off.
 * In Modern Warfare 2, if the player is playing Special Ops, when a dog jumps on him, the player's friend can kill the dog while it is on him, before or after the player fails to grab the dog.
 * In World at War, if the server settings are to have life set to 2x, dogs are relatively ineffective as they take two hits on the enemy to kill them. Considering this is outside the dogs natural programming (it should only take one strike to kill) it will stand there for a few seconds before dealing the deadly strike giving the player time to kill the dog. It should be noted, however, that the dogs themselves have double the life meaning they are harder to take down.
 * Because of the incredible feats dogs sometimes pull off in order to kill an enemy in World at War, some have jokingly compared them to "Underdog." This generally comes after the dog appears to fly through the air over a barrier.
 * In Call of Duty: World at War multiplayer, chains and collars can be heard jingling while dogs are running around even though the dogs have no collars.
 * The dogs in all of the Call of Duty series (with the exception of Call of Duty: World at War) seem to be of only one breed, German Shepherds.
 * Sometimes when a dog is killed a glitch will occur causing the dog's corpse to float motionless in mid-air. Other times a dog may die and remain frozen in a standing position as if it were still alive. This can confuse some players, causing them to shoot at the corpse not realizing it is dead, and thus giving away their position to the enemy.
 * Normally, dogs are not counted towards killstreak rewards. However, on the Wii version of World at War, there is a glitch that will cause them to count. It is more likely to happen if the player dies immediately after calling in dogs, and then the dogs get multiple kills and then when you get a kill, if the dogs passed the killstreak kills needed, each kill will award you with the killstreak.
 * Dogs are affected by Tabun Gas. Proof of this can easily be seen in the Kill Cam if a player gets killed by a dog hit by such a grenade. The dog's vision will be distorted in much the same way that a human player's would be.
 * Dogs are much more likely to fall victim to traps like Bouncing Betties and Martyrdom grenades, as they are not programmed to avoid them. Defending players may find it irritating to lose their Betties to dogs, when they could have killed enemy players instead.
 * It is odd that World at War has dogs as a killstreak, considering they appear in the least amount of missions out of the three games. The same goes for Black Ops.
 * In World at War's multiplayer, all friendly dogs are seen as German Shepherds. All enemy dogs are Black Belgian Malinois.
 * In World at War, the killstreak for Dogs is just "Dogs," while in Black Ops, they are now known as "Attack Dogs."
 * In Nuketown, If you call in dogs and then call in chopper gunner, you can see the dogs leaving (climbing the fence, etc.,.) and going into some boulders.
 * In Call of Duty: Black Ops multiplayer, it is possible to be killed by your own attack dog, if it misses its target and hits you instead.
 * In "Call of Duty: Black Ops," on the multiplayer level Berlin Wall, dogs can travel through the red zone without being shot by the guard towers.
 * In Modern Warfare 2, it's possible for the dogs to tackle the player and they will only see the dog's stomach. In this case, it will impossible to kill them and the player will always die. Note that when this does happen, the dogs appear to have shriveled stomachs, implying that they are underfed.
 * In The Enemy Of My Enemy, some dogs will not tackle the player and instead will just stand their barking at them, as if they do not know if they are friendly or not.
 * Only on the Wii version can Ghost Pro protect the player from attack dogs
