Mr. Muffykins would do), a guard dog (who merely has to look imposing, like a Mastiff) and an attack dog (who has to be athletic and very trainable). Your stereotypical Angry Guard Dog, on the other hand, is all three. It looks intimidating, and if you enter its territory it will bark, but only on the way to mauling you. This dog's bite is every bit as bad as its bark. Ironically, few Angry Guard Dogs are pitbulls. This has less to do with emulating realism and dodging current stereotypes than with indicating the old age of this trope. Bull terriers were highly regarded during the World War II era, and considering current media trends, no one wants to really highlight them in an opinionated way. And strangely enough, while bulldogs tend to be used in media for this trope, they tend to be one of the worst suited breeds for guard dogs in real life, due to their amiable disposition and poor athletic ability. A pack of these (usually three or more, and usually Dobermans) is standard issue for any scrapyard or vehicle impound lot, while any Big Fancy House worth its salt will have them chained up and ready for the master to snarl "release the hounds". Nowadays, the trope is mostly found in cartoons. They occasionally subvert it, showing the dog is a big softie and/or coward if confronted, with the Aesop that a bully's bark is always worse than his bite. See also Right-Hand Attack Dog, and Hellhound (if a Hellhound is also an Angry Guard Dog... be very, very afraid.) Contrast Big, Friendly Dog (although this Trope can overlap when their friend is the one they're guarding), They Have the Scent!. Neutralized by Scare the Dog. Sometimes named Fluffy.

Specifically, he’s a hero who dresses in a white dog suit and often acts as a dog… Complete with ‘‘slaughtering any monster stupid enough to appear in the city he has declared his territory’’.

Films — Live-Action
- The Sandlot has a subversion in "The Beast," a Mastiff that is shown to have a collection of balls that kids have knocked into its domain and given up for lost. A good chunk of the movie revolves around the kids various efforts to get back a ball signed by Babe Ruth that went into its yard.

They're big dogs however (Rottweilers), and in the second instance the Joker has probably made them more vicious than they already were (feeding them human meat, among other things).
- In the 1980s Henry Winkler movie Night Shift, the rather nebbishy and timid main character is shown to be frequently tormented by a neighbor's dog who relentlessly pursues him through the apartment complex where he lives, barking furiously.

- One appears in Stand by Me (and the original Stephen King novella The Body), though it turns out his fearsome reputation is somewhat overblown.

- Older Than Feudalism: In Classical Mythology:
- Cerberus is the three-headed guard dog of the Underworld, assigned to prevent the dead from leaving, as well as making sure living people don't try to slip into the Underworld to visit, or worse yet, rescue dead loved ones or dead prophets. It's always a big deal when someone like Orpheus, Hercules or Aeneus finds a way to get around him.
- Orthus, Cerberus' lesser known two-headed brother. He's best known for being the guard and herd dog of the fabulous red cattle of the triple-bodied monster Geryon, and is, according to the poet Hesiod, the father of his siblings, by his mother Echidna, the Chimera, the Sphinx, the Hydra, and strangely, the Nemean Lion.

- Watership Down:
- Richard Adams' Watership Down plays the trope straight and desperate. The hero rabbits consider calling dogs much like humans might consider using an atomic bomb in a war: it destroys their enemies, but at a heavy price. In this case, they are alerting the dog and the owning farmer that there is a rabbit warren near the farm. Considering the Efrafans are fighting to massacre the Watership Down warren, that was considered the lesser of two evils.
- In another instance of this trope in the book, the Lapine tale "Rowsby Woof and the Fairy Wogdog" presents the titular Rowsby Woof as an obstacle between El-Ahrairah and the cabbages in a human's garden.
- Watership Down certainly plays up the fear factor from a big angry guard dog. You think they're bad? Try them when you're just a little rabbit and you're a fraction of the size.
- Harry Potter:
- Carcharoth from The Silmarillion is an angry guard wolf. In this case, though, it's not so much the getting in as the going out that turns out problematic.
- The Andromeda Strain mentioned a rather creepy version in passing: vicious guard dogs who had undergone laryngectomies, so they couldn't make any bark. You'd never hear them coming until they were already tearing your throat out.
- In the Discworld novel Going Postal, when Moist von Lipwig is undergoing initiation into a secret society of postmen, part of the training is to get past some of these (a natural enemy of postmen everywhere). Concluding that they are Lipwigzers, a very popular guarding breed hailing from his hometown, he briefly dominates them by giving them commands in a stern voice. Played for Laughs after the dogs are led out, and Moist finds out they were NOT the breed he thought they were...

- Guard dogs (implied to be Dobermans or Rottweilers) appear at the prologue of Warrior Cats: A Dangerous Path, brought to a compound by humans to find the pyromaniacs who set the forest on fire in Rising Storm. They prey on pigeons and later cats, killing off several important cats and deforming Brightpaw. This makes the cats especially unsettled as they're usually the top predators in the forest.
- In The Savannah Reid Mysteries, a dog named Beowulf. He only grudgingly allows Savannah to pass after she gives him some meat. When she tries this with Hitler, Satan, and Killer in Death by Chocolate, on the other hand, the three little dogs become Savannah's best friends.

- In Andre Norton's Ice Crown, the dire hounds. Since their keeper is Imfray's friend, he, Roane, and Imfray's rescuers are hidden in a shed behind their pen.
- For Survivor Dogs, this is bound to happen in a series starring dogs. The main example is the Fierce Dogs pack, a pack consisting of Dobermans led by the bloodthirsty Blade. They're a group of ex-guard dogs who banded together after their owners fled during an earthquake. Even the White Sheep Storm, who escaped the pack as a puppy, is more aggressive and fight happy than the other dogs in the Wild Pack.
- In Margin Play by Eric Plume, Amber encounters a Doberman that fits this trope at Thom Cullen's house. When it rushes her, she wallops it with a rolled up Wall Street Journal.
- Nick Velvet: In "The Theft of the Overdue Library Book", Nick has to work out how Sandra Paris abducted someone from a men's room that had an angry guard dog outside its only exit.
Live Action TV
- One scene in Sons of Anarchy involves Juice and Tig trying to steal a truck from a locked compound. In order to subdue the Dobermann guarding the area, Juice is advised to drug the animal, which he does so using crystal meth. Leading to a very cranky guard dog indeed.
- The A-Team: In the episode "There's Always a Catch", the team encounters a ferociously barking Dobermann called Cutter while trying to buy replacement parts for the clients' boat. It's unknown whether he would have done anything more vicious because he's tied up, although the owner threatens to set him on them.
- Dog the Bounty Hunter had a dog at the home of a bail jumper's family who dragged a truck tire it was chained to when trying to get at the team and had to be maced to make it back down.

- Ditto Pit Bulls and Parolees, where even the pit breeds trained to fight dogs are very people-friendly.
- Magnum, P.I.: Robin Masters' estate, 'Robin's Nest', is occupied by two Doberman guard dogs, Zeus and Apollo. Interestingly, although Magnum is in charge of security for the estate, the dogs both belong to and answer to Higgins, not Magnum. They don't really like Magnum much.
- In It's Me or the Dog, Victory considers overly protective dogs to be counterproductive to home safety (as they're just as likely to menace harmless strangers, causing problems for the owners), so she re-trains these types of dogs to associate guests arriving with something good happening (i.e. delicious treats).
- Person of Interest: A neo-Nazi tries to use one to intimidate Reese. Reese explains that the dog only appears angry because it does not respect its current owner who does not know how to handle such a well trained animal properly. Reese, on the other hand worked with this type of guard dog before and knows the Dutch commands it was trained to obey. A few Dutch phrases later Reese has a new dog.
- Though the dog only obeys commands in Dutch, he certainly understands certain words in English, like "walk", "leash", and "treats".
- Al Mundy deals with them occasionally on It Takes a Thief (1968).
- In the made for TV movie Trapped (1973), James Brolin plays a deadbeat dad attacked in a departments store and left unconscious. He is not discovered and the store is closed and is patrolled by unattended attack dogs.

- Murdoch is attacked by one while investigating the ratting barn in the Murdoch Mysteries episode "Let Loose the Dogs".
- The protagonist of the short-lived series Lucan (who was raised by wolves) is forced to kill an attacking Doberman. The experience reduces him to tears.

- Motive: In "Creeping Tom", when the police arrive at the scene of the crime, they find the Body of the Week is guaraded by an angry guard dog that barks at anyone who tries to approach the body. Later Angie realises that that while the dog barked at all the police, it did not bark when the intruder was in the house, meaning it was someone the dog knew and trusted.
- Voyagers!: Bogg encounters a loudly barking German Shepherd while trying to get the gas for Lindbergh's flight.
- Garfield features, makes fun of, and deconstructs this trope to no end.
- Inverted in Peanuts where Snoopy was terrorized by "World War II", the cat next door. Occasionally Snoopy himself would be put in this role. Performance ranged from lackluster (falling asleep while guarding Peppermint Patty) to metaphysical ('You try to warn them the world's gone mad ... ') to, and I'm not kidding, More Dakka (how many guard dogs have ever mounted a machinegun to their house?!).
- The Angriest Dog in the World by David Lynch: "The dog who is so angry he cannot move. He cannot eat. He cannot sleep. He can just barely growl. Bound so tightly with tension and anger, he approaches the state of rigor mortis."
- 'Irish' Murphy's dogs in Footrot Flats: Tiger, Wolf and Creampuff.
- Played with but generally averted in Mutts. The guard dog, while surly, rarely gets angry enough to threaten anyone. He's just as likely to elicit sympathy from being tied up all the time.
- In the Amazing Stories episode "Family Dog", after the dog twice fails to protect the house from burglars (he was ill the first time, got locked out by the burglars the second (, the father takes him to guard dog school. The father is unimpressed when he returns for him and the dog is as happy-go-lucky as ever. . . until the instructor snaps her fingers and the dog instantly turns into a snarling, barking beast. It pays off when the burglars return again, but works too well when he attacks the father (trying to get in after accidentally locking himself out).
- Subverted with the "Kennel from Hell" match during WWE's Unforgiven 1999. The idea was a steel cage match inside Hell in a Cell, where the inner cage was surrounded by vicious dogs. Turns out the dogs weren't so vicious, as they spent more time peeing and crapping on the floor and mating with each other than actually intimidating the wrestlers. The wrestlers were more in danger of slipping on the dogs' mess than being torn apart by them.
- Paranoia has doberbots, whose combat programming typically consists of "Attack someone until he dies. Attack someone else until he dies. Attack someone else until he dies..."
- The Yu-Gi-Oh! game has Guard Dog, a mean-looking Beast. (Whose name, according to its doghouse, is "Beth".)
- Several Deus Ex missions, starting with the first Hell's Kitchen mission, feature Dobermans - they are always trained attack dogs on patrol.
- Mario & Luigi: Bowser's Inside Story has Broggy, the dog of the shopkeeper Broque Monsieur. Initially annoyed enough that it was willing to take on Bowser in a Boss Battle, you actually get to walk this dog after collecting all the Blitties... translated as a new Special Attack for the rest of the game involving him and fifteen kittens swarming the enemies/bosses. It looks hilarious. note
- The Elder Scrolls IV: Oblivion: Oddly used and subverted. Occasionally bandits will have guard dogs who sit around barking to themselves, even if you are covered in blood from their owner. They only seem to turn hostile when their owner does.
- An alien variant appears in The Dig, being revived to prevent anyone entering the tomb of the Inventor. The way to get rid of it is somewhat counter-intuitive.
- Another one shows up right near the end once you open the Eye. In this case, the way to deal with it is rather obvious.
- The first level of Earthworm Jim, set in a garbage dump, has spinning balls of fury next to doghouses which are these.
- Toe Jam And Earl in Panic on Funkotron: The game features an old lady and her poodles as enemies. The poodles start as dangerous, but if you capture the lady before them they turn into whirling balls of destruction.
- The Castle of the Crown in King's Quest VI (and The Silver Lining]]) is guarded by a regiment of bipedal, talking dogs. They take any threat to the royal family very seriously. However, Captain of the Guards Saladin is a Reasonable Authority Figure.
- Runner from Septerra Core. He's a robot dog built by Grubb, and joins your party when Grubb does. Other dogs bare their teeth; Runner bares a beam cannon.
- World of Warcraft: take a wild guess what Houndmaster Loksey of the Scarlet Crusade does in his spare time. Other Crusaders sometimes have dogs accompanying them; they seem to have picked up the Knight Templar disposition of their owners.
- In Command & Conquer: Red Alert 2, both the Allied and the Soviets have attack dogs (German Shepherds and Russian Huskies, respectively) and both are excellent scouts and able to maul most infantry to death. Some mods also give the Yuri faction its own attack dog; these are usually mutated and have poisonous bites on top of their bad temper.
- In Command & Conquer: Red Alert 3, the Allied scout unit is the Attack Dog, a German Shepherd capable of killing infantry with its bite or paralyzing them with its bark. Not to be outdone, the Soviets deploy Angry Guard Bears.
- In Dragon Age II, Aggressive!Hawke can turn his/her Mabari into one of these. During Act III, a burglar will sneak into the Hawke estate and is cornered in a wardrobe by Dog. Aggressive!Hawke can order Dog to devour the burglar. Fade to Black over the burglar's bloodcurdling screams as he's torn apart.
- Mass Effect 2 features FENRIS mechs, essentially dog-shaped Mecha-Mooks.

- The Mental Series has one of these as an obstacle. Greg must take it out with his slingshot before you can move on.
- Available in WarWind for the Marines after building a kennel. As you could suppose, it is not very useful on a planet inhabited by all kinds of monsters and alien races using heavy weaponry.
- A very strange alien being that functions as a guard dog appears in the horror adventure game Dark Seed, in the game's Dark World. It guards a bridge and has to be lured away by throwing a stick for it to fetch.
- Big Dog from Nuclear Throne, a three-headed hellhound that lies at the end of the Scrapyard area.
- Played with in Bayonetta 2 with the Lethal Joke Item, the Chain Chomp.

- In Metal Gear Solid 3: Snake Eater There are guard dogs around the Russian base that Naked Snake can kill.
- TinkerQuarry: Invoked with Staya. He's a mechanical toy dog with clock parts, and he wants to keep everyone from leaving the Dollhouse. Considering his clock parts, you could say he's a literal watchdog.
- Aibo, from Unintentionally Pretentious, Mia's robotic guide dog. Also her Angry Guard Dog with a manual Berserk Button.
- In Sinfest, Tangerine and Lil' E discover that Cerberus can be this. (It's lucky that Satan still has a soft spot for Li'l E.)

- In Batman Beyond, Bruce Wayne has a Great Dane named Ace (not the Bat-Hound, but undoubtedly a Mythology Gag) who was actually raised for dogfighting and rescued by Bruce.
- The Doberman at the dog pound in Chip 'n Dale Rescue Rangers, episode "To the Rescue" part 4.
- Doug had an episode involving the "classic" version, a bulldog who was preventing Doug and Skeeter from getting a (borrowed and presumably expensive) frisbee out of a yard.
- Taken to absurd lengths in Eek! The Cat, where the neighbors' yard is guarded by Sharky the Sharkdog, who is a literal shark/dog hybrid. Sharky would often go out of his way to terrorize the well-intentioned Eek!, regardless of where they were. Leading to the classic episode involving Annabel's pool in the backyard, a submarine full of ocean-exploring waterfowl parodying Jacques Cousteau, and the "Shark" part of things suddenly being much more literal.
- In The Fairly OddParents!, Timmy's ploy of getting friends Chester and A.J. to rescue him from "vicious guard dogs" backfires when Cosmo and Wanda are too distracted to play the part, and the junkyard's actual vicious guard dogs go after Timmy instead.
- Remy Buxaplenty's family owned some vicious guard dogs themselves (among them Pit Bulls).
- Garfield and Friends had Garfield citing the Angry Guard Dog as an especially annoying trope, since he never understood why a dog would automatically defend a mouse or immediately attack a cat for no reason. (Garfield thinks that dogs are ruled by their stupid instincts. Garfield himself does run afoul of dogs occasionally, but it's usually after baiting them.)
- The Looney Tunes "Sam the Sheepdog" cartoons subverted this; Sam protects the sheep but has no personal animosity toward the wolf, as a Punch Clock Hero — in one, we see them both punching out mid-fight, having lunch, and getting back into position afterwards.
- Foghorn Leghorn's nemesis Barnyard Dawgis one, but that's only because Foggy makes him angry all the time.
- The earliest example might be in Oswald the Lucky Rabbit, episode "Weary Willies" (1929), with hobos Oswald and Pete trying to get a roasted turkey off of a suburban windowsill. Blocking the way is a fierce bulldog who, after several typical blackout gags, is ultimately sent chasing after the cop who'd been pursuing Oswald and Pete for vagrancy earlier.
- The Ren & Stimpy Show played with this in "A Yard Too Far". After Ren realizes that attempts by him and Stimpy to steal food from a windowsill are too similar to a golden-age cartoon plot for his comfort, he immediately sends Stimpy (a cat) to scout and flush out the obligatory guard dog. Stimpy returns and assures him there is no dog. Ren goes into the yard, and is promptly mauled by a guard baboon.
- Earl the bulldog from Rocko's Modern Life.
- Bronx from Gargoyles is both this and a Big, Friendly Dog, depending on situation or who is around.
- The Pickles live next door to one such dog on Rugrats, often mentioned but only seen twice — three times if you count the Whole Episode Flashback before it became the ferocious "monster dog" the babies had come to know.
- SpongeBob SquarePants once had to get past a vicious junkyard guard worm, giant worms being the "underwater" equivalent of dogs.
- Arnold the security dog from Tiny Toon Adventures.
- Tom and Jerry: The most famous example is probably Spike the Bulldog from these cartoon shorts. When Spike's popularity caused a softening of the character, the writers merely gave him other reasons to attack Tom (a misunderstanding, trying to set an example to his son about how dogs act, a Papa Wolf attitude toward those messing with said son, etc.)
- A 1963 Daffy Duck cartoon involved Daffy trying to contact a millionare, and having to make it past the man's pet bulldog first. Daffy faced a similar situation in the 1948 cartoon "Daffy Dilly", but in "Dilly" the obstacle was the millionare's anthropomorphic dog butler.
- A 1998 short of Life with Loopy had Seymore, who confiscated anything going into his yard, including humans.

- In The Simpsons, Mr. Burns has a pack of these at the ready whenever his guests have overstayed their welcome. Or if he needs a good chuckle.

"That hippie didn't think that was too grooooovy
- Although they do get old and tired, leading Burns to reminisce about one dog's attack on his first hippie:
- On one Sylvester the Cat and Tweety Bird cartoon, Granny seems to have hundreds of guard dogs in her backyard, all of which Sylvester has to get through to catch Tweety.
- Shows up near the end of The Amazing World of Gumball episode "The DVD", during the scene where Gumball and Darwin are chased through the neighborhood by their mother. Gumball and Darwin run away from it. Nicole starts riding it like a horse. The dog in question looks like Domo, but quadrupedal with a tail and ears. This is used as a generic "dog" model throughout the show, including one time Gumball had to cartwheel through a yard full of them and another where he chains one up in his yard to make his house look bad.
- Cerberus comes to visit Ponyville in an episode of My Little Pony: Friendship Is Magic. It's placated by Fluttershy.

- In the second act of the episode "Museum Madness", Bogus finds himself getting chased by a security guard's Doberman throughout the museum.
- An Angry Guard Dog rottweiler served as The Dragon to Ratty in the first act of the episode "Totally Bogus Video". Too bad that he only showed up in the first act.

- Oggy and the Cockroaches: Bob. In a few episodes, he actually IS a guard.
- In the animated "Family Dog" episode of Amazing Stories, the dog fails to stop two burglars in two consecutive occasions, so he's taken to an obedience school where he's trained to become, in the words of the owner, "a quivering, snarling, white-hot ball of canine terror." When the burglars return, not only does the dog viciously attack them, he even follows them home. There they end up adopting him and using him to commit crimes, until there's a falling out and the dog attacks them again before returning home.
- In the We Bare Bears episode "The Demon", the titular "demon" is the dog of Chloe's neighbor, a crazed monster that rips to shreds anything it gets a hold of. It also turns out to be a tiny French Bulldog, albeit a savage, hyperactive one. She and Ice Bear sneak in when the dog gets her hoodie. In the end, they discover that wearing the hoodie calms it down, so they let him have it, much to the delight of the neighbor.
- The Pink Panther has come across a few such dogs in a fenced yard, such as in "The Pink Package Plot" (a terrorist was forcing the Panther to deliver a package containing a Time Bomb to an estate) and "Spark Plug Pink" (where a spark plug the Panther needs to get his lawn mower going accidentally lands in the dog's yard amongst his bones).
- Although most watch dogs are not true guard dogs, but are rather intended to alert the owner of any trespassers, this aggressive variant is not that rare with many a well-protected compound (whether civilian or military) or private home, especially gated properties.
- There have also been an amount of even more aggressive examples of dogs being trained for outright attacking on a battlefield (an ancestor breed to modern-day Mastiffs, Molossus have been said to have been used for the purpose by the ancient Greeks and Romans), though the examples of them serving as a remotely noteworthy portion of one side of a battlefield's punch are very uncommon compared to cavalry, and are dwarfed by attack dogs used for sentry duty or sniff out hiding enemies...not to mention the dietary requirements of a large number of dogs was probably beyond most invading armies' logistical capabilities. Their use to attack on the battlefield likely more relied on the negative psychological effect of being hounded (no pun intended) by a large pack of vicious, snarling dogs given that a trained, shielded ancient warrior (let alone a modern one with a gun and bayonet) shouldn't have too much trouble fighting off a dog.
- From the book The Truth About Self-Defense written by law enforcement training instructor Massad F. Ayoob:
- WATCHDOGS ...A mobile, four-footed burglar alarm. [They] bark insistently and steadily when an entry is attempted, and ... [go] to the entry point to pinpoint it for you.
- PROTECTION DOGS are animals with advanced obedience training. On your command, they will bark and lunge at an aggressor, snapping at him without actually biting him. Also upon your command, they will immediately sit or lie and fall silent. Their training is oriented strictly toward a deterrent show of force; if your attacker persists, the animal will have to fall back on its natural protective instinct and bite him. A properly trained protection dog will also perform all the functions of a watchdog.
- ATTACK DOGS have been trained to sink their teeth into people on their master's command, or when they observe their master under assault. Once resistance from the suspect ceases, a true attack dog will let go of him. It will do the same on command, no matter how excitement-charged the atmosphere, if it has been properly trained and selected. Normally, the dog will only bite if given the proper command, or if the animal sees its owner or a family member under attack. The attack dog is at the maximum level of obedience training. After the master has ordered it to put a suspect on point, the dog can be called back, and even ordered to "make friends." It feels no personal animosity toward the person it is ordered to attack; it is a canine technician, doing a job on the orders of its human boss.
- GUARD DOGS represent the deadliest level of canine training. These animals either walk with a sentry, or patrol alone in an enclosed space. Their function is to apprehend and neutralize any human intruder. They do not stop biting when the suspect stops resisting; they stop only when the human stops MOVING. They are likely to be trained to go for the throat or genitals. Guard dogs are trained to kill and maim. The only legitimate use of a guard dog is in wartime, or when guarding an area so sensitive that human intrusion could result in awesome public danger, such as a nuclear weapons facility.
