- "Fetch me their souls!"
- — The Demonic Announcer at the beginning of a Hellhound round.
The Hellhounds are an aggressive and murderous type of zombies first introduced in the Zombies map Shi No Numa. These variant of zombies are encountered on their own special round in Shi No Numa, Der Riese and Kino der Toten, and make additional appearances in Dead Ops Arcade, Moon and Green Run.
They are essentially zombie-dogs that are the mutated version of Samantha's pet, Fluffy, when it was put in a Der Riese mainframe teleporter, turned into a deadly Hellhound and later had puppies. They randomly spawn throughout the map (a ball of lightning will usually indicate whenever they spawn) in packs of two to four (depending on the amount of players) every four to seven rounds and their sole objective is to kill the player by streaking towards them and either attacking with tooth and claw or by exploding. The ground shakes whenever they spawn and there will be a heavy fog covering the map. There are two variants of the Hellhound: the flaming Hellhound, which on top of being perpetually on fire explodes on death, and the normal Hellhound, that simply fall to the ground and not explode when killed. When the last Hellhound of their special rounds is killed, it will always drop a Max Ammo power-up. One exception to this is Shi No Numa, where the Max Ammo may not be dropped by the Hellhound, but the next zombie the player kills. The electric bolts that appear during a Hellhound round are supposedly linked towards the teleporter incident that occurred at the Der Riese facility.
In Green Run, through a Custom Games lobby, the host has the ability to turn on/off a Hellhound round if the host has selected a Survival or a Grief game mode map. The only maps that are available for Hellhound rounds are Town, Bus Depot and Farm.
In Der Riese, there are a series of radios that depicts the Hellhound's creation. Dr. Maxis and his assistant, Edward Richtofen, were doing tests at the Der Riese facility. One of the tests involved Samantha's dog, Fluffy. When teleported, Fluffy vanished and later reappeared as a demonic variant of Samantha's dog; Fluffy became a Hellhound. When this occurred, Richtofen followed through with his plot to get rid of the Maxis' by locking them in the teleportation laboratory with the possessed Fluffy and sending them through to the Aether. Dr. Maxis was teleported to an unknown location, while Samantha was sent to Griffin Station. Samantha seems to now control the Hellhounds as she attempts to kill Richtofen. One of the radio messages hints that Fluffy was pregnant, explaining why there are multiple Hellhounds.
- If one uses Insta-Kill to kill the last dog of a round, they will not drop a Max Ammo.
- The Hellhounds have several different appearances just like the zombies. Some are large and intimidating while others look frail and badly burned.
- The Hellhounds appear every five to seven rounds. The first wave of each party is in rounds 5, 6 or 7, and the others wave are every four or five rounds
- Hellhounds will attack certain players and do not switch between targets until the one they are after is downed.
- In Der Riese, there is a door with a warning sign and a Hellhound head nailed to it. On the floor inside of the door, there is a lot of blood.
- In Der Riese, if a teleporter is near by during a Hellhound round, many Hellhounds will spawn out of the teleporter.
- Also, on Call of Duty: Black Ops (Nintendo DS), there is no specific Hellhound round. Hellhounds can appear from round five and have increasing likelihood of appearing each round. These Hellhounds only spawn coming from barricades like zombies, and will knock down the barricades by jumping on them.
- In Der Riese, Dead Ops Arcade and Moon, they can appear alongside the zombie horde.
- Hellhounds were originally going to appear in "Five", since there are character response quotes for them in the game's files. This can be seen here.
- In the game files there is a scrapped audio file with the name
mx_dog_wave_b, suggesting there was to be a song played during the Hellhound round. The song can be heard here.
- The Temple is the only Call of Duty: Black Ops (Nintendo DS) map that does not feature Hellhounds.
- A part of "Beauty of Annihilation" plays at the end of a Hellhound round on Der Riese, the Call of Duty: Black Ops version of Shi No Numa and Der Riese, Kino der Toten and Green Run.
- In Call of Duty: Black Ops II, their eyes remain yellow-orange, rather than blue like the zombies Richtofen controls. This hints that Samantha may still possibly control them.
- Dempsey snickers "Devil Dogs" at times upon a Hellhound round, a reference to the nickname (supposedly given by the German military) of the U.S. Marine unit he was a part of during the Battle of Belleau Wood, according to his letter.
- Using PC mods on Call of Duty: Black Ops, it is possible to obtain the weapon dogs use to attack. When used by a player it appears to be a floating TNT plunger and a pink box in the right hand.  It is referred to as dog_bite_zm. The map will crash if the weapon is dropped.
