Just because humans are uncomfortable with the subject of nudity, doesn't mean we're the only species to [[BarbieDollAnatomy get our nudity censored]] in fiction -- it is just as common for regular everyday animals to get this treatment as well.

This is usually a [[LawOfConservationOfDetail concession of realism for the sake of the artist]], as most artists would prefer to avoid drawing an animal's genitals or anus themselves, taboo or no taboo. It can also be a product of stylization, to which animals are especially prone, and which tends to remove unappealing or unimportant features, oftentimes to make them cuter (for example, stylized dogs tend to lack claws and lips). Othertimes (by which we mean most of the time), whether or not Fido has gonads is way beside the point so it's simpler to leave them out unless you mean to draw attention for a narrative purpose or a cheap gag.

This is technically TruthInTelevision for animals such as birds, reptiles, amphibians, fish, and invertebrates, whose genitalia are typically visible only as a small underside 'vent' between the rear limbs (and easy to miss even without feathers or scales to obscure them). That's not a form of censorship, it's just LawOfConservationOfDetail (remember: NobodyPoops).

On the other hand, when depicting mammals (save for platypuses[[note]][[PerplexingPlurals Platypi? Platypeese?]][[/note]] and echidnas), there's a common assumption that an animal's natural fur will adequately preserve the creature's modesty. However, observation of most real mammals will show that their fur is actually thinner in those places (so it doesn't get soiled when nature calls, and is easier to clean if it does). Also, many species' coats of fur are just too short to adequately conceal the features of their genital or anal area in the first place. Anyone who has seen a male pig or non-neutered male dog, for example, will have no doubt noticed the prominent pair of features between its rear legs. However, fur mostly consealing the animals genitalia is actually the case in some animals as a rule of thumb, mammals that live further North will have thicker and longer fur and are more likely to justify this as the longer fur protects their naughty bits from the cold.

The sole exception to this censorship is the four teats of the female cow (and also quite often the [[AnimalGenderBender male cow]]), which are always present, thanks to the iconic image of the country milkmaid. The only time cow udders were ever censored was in the early 1930s, when MoralGuardians became offended by the showing of Clarabelle Cow's bare udders in the [[ClassicDisneyShorts 1930 Disney short]] "The Shindig." Other female mammals, even goats, are almost never shown with explicit mammaries, even in scenes where her offspring are shown nursing from her.

For the purposes of defining examples, only animals who are mostly or "completely" normal in physical appearance (e.g. not visibly [[SlidingScaleOfAnthropomorphism anthropomorphized]]) and animal mannerisms should be considered. For cases where a creature is sufficiently anthropomorphized that the UncannyValley effect might occur (such as with {{Funny Animal}}s in a few cases and ''especially'' with PettingZooPeople), see NonhumansLackAttributes instead.

!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* In the ''GingaDensetsuWeed'' anime, every dog is drawn this way, despite the fact one character is known for [[GroinAttack biting the testicles off]] of his enemies. This is sometimes averted in the manga though, as some panels clearly show genitals and anuses.
* Averted in many anime appearances of {{Tanuki}}, raccoon-like creatures that are often depicted as having [[GagPenis gigantic testicles]] as a symbol of luck.
* In ''Manga/{{Naruto}}'', at least with a certain giant armadillo.
* ZigZagged in ''What's Michael'' and ''Jarinko Chie'': testicles (but nothing else) are shown.
* Totally averted in ''{{Gon}}''.
* Mostly played straight, but the anus part of this trope is sometimes averted with Chi from ''Manga/ChisSweetHome''
** Also averted a lot wiith Kuroi in the manga, he is shown with a scrotum when seen from behind.
* Played straight in ''Manga/CatParadise'', despite the rather frequent panels with the cats' butts in full view.
* Averted in ''{{My Neighbor Totoro}}'' with the Catbus- when HE jumps down from something, the testicles are definitely there.
* In the anime version of ''Literature/UchoutenKazoku'', tanuki in their animal form are distinctly lacking the attributes that define them in other depictions.
* Also ZigZagged in ''Webcomic/AxisPowersHetalia''. Animals are usually drawn with anuses, but male animals lack testicles.

[[/folder]]

[[folder: Comic Books ]]

* Averted in ''{{Bone}}'' with Roque Ja the mountain lion, who when seen from behind has a very prominent scrotum.
* The anus part of this trope is averted with the comic book version of ''ComicBook/TheSmurfs'' cat, Azrael.

[[/folder]]

[[folder: Animated Film ]]

* {{Averted|Trope}} by volumes in ''PomPoko'', where the testicles of the tanuki are very prominent, both art- and plotwise -- though this is more due to the fact that tanuki having a very large scrotum is an aspect of Japanese folklore than any bizarre decision on part of the director.
* Averted in the movie versions of ''ThePlagueDogs'' The dogs as well as most other animals are drawn anatomically correct.
* ZigZagged in 'WatershipDown''. Although the dogs are anatomically correct, the bucks are generally not drawn with anything showing no matter how close the camera comes. With dogs, on the other hand, it's quite obvious.
** TruthInTelevision, male rabbits are very hard to distinguish from female rabbits, the differences in the two sexes' external genitalia are very subtle.
* ''Extremely'' applicable for the rats from ''WesternAnimation/{{Ratatouille}}'', as male rats normally have testicles as big as their snouts. When Remy walks upright, his scrotum really ought to have been dragging on the ground.
* Played painfully straight in ''Disney/{{Dumbo}}'' where all of the circus animals even have to rely entirely on [[DeliveryStork Delivery Storks]] in order for them to have offspring.
* Poor Bruce from ''WesternAnimation/FindingNemo'' was originally animated with prominent claspers, as would be appropriate for a shark his size. Obviously they didn't make it to the final version.
* ZigZagged in ''WesternAnimation/SpiritStallionOfTheCimarron'', where the titular horse, as well as the Colonel's horse and the cowboys' mounts, sport a visible sheath in many shots. However, Spirit in particular lacks the necessary features to qualify as a stallion, despite the fact he is always referred to as one. And this isn't due to discretion shots either. Whilst the domestic male horses could realistically be geldings, Spirit doesn't have this possibility, making it particularly jarring for anyone familiar with equine anatomy. What's more, as a foal he seems to even lack a sheath, and again, this is not due to the camera angle being discreet.
* Averted in ''WesternAnimation/TheTripletsOfBelleville''. Bruno is anatomically correct.
* Shows up in ''WesternAnimation/PussInBoots'' and the rest of the ''WesternAnimation/{{Shrek}}'' franchise where the cats, donkeys, pigs, mice, and other animals don't have the excuse of being rendered in a cartoony style.
* Also shows up with Snowy the dog in the 2012, CGI ''Film/TheAdventuresOfTinTin'' movie as he doesn't have the excuse to be rendered in a cartoony style.
* Talking Dog urinates on the metallic hand of a giant gorilla in ''ThePowerpuffGirls Movie'' but otherwise we see nothing on him we shouldn't.
* [[Disney/TheLionKing Pumbaa]] doesn't even have an anus. [[ToiletHumor He can fart]] nonetheless.

[[/folder]]

[[folder: Live Action Film ]]

* In the 1933, 1938, and 1976 versions of ''Film/KingKong'', Kong had no nipples.
* Franchise/{{Lassie}} is a female dog (note the root of the name is '''Lass''' not '''Lad''') played by males with their belly hair coiffed very carefully to cover up the naughty bits.
* ''HarryAndTheHendersons'' played this one straight. Harry's fur is a bit thicker in that area, but such doesn't really conceal genitalia in hominids.
* In ''Film/CatsAndDogs'', Lou is played by a couple of different beagles. Any scene in which he rolls on his back (particularly if someone is scratching his belly) will be played by a female, who naturally has less in that department. Despite this, Butch's comment on his immaturity is "He's still got his you-know-whats, for cryin' out loud!"
* Shows up in the ''Film/ScoobyDoo'', ''Film/AlvinAndTheChipmunks'', ''Film/{{Garfield}}'', and ''WesternAnimation/YogiBear'' live-action films, where they don't have the excuse of being cartoon animals.
** A deleted scene from ''Film/JayAndSilentBobStrikeBack'' involving the Scooby Gang averts this.
* A particularly curious example is in ''SonOfTheMask'' where Otis the dog is partly played by a real dog and partly by horrifying animation. When the dog is real, it obviously has the equipment you would expect but as soon as it puts on the mask and becomes animated the downstairs department is noticeably lacking. This could have been {{Hand Wave}}d as being an effect of the mask itself, had it not been for the fact that the whole premise of the movie is that a human male impregnates his wife whilst wearing the mask.
* [[Film/AliceInWonderland The 2010 version]] of ''Literature/AliceInWonderland'' has the family of bloodhounds. The mother of the puppies has no discernible mammaries, and the father has nothing between his legs with which to create said puppies, even when he flops down on his side in front of the White Queen with his crotch pointed right at the camera.
* In ''Film/RiseOfThePlanetOfTheApes'' none of the apes have any genitalia. Chimpanzees have gigantic testicles, it's impossible to censor their parts without it being obvious.
* Averted with the tiger, Richard Parker in ''Literature/LifeOfPi'' as he is rendered with testicles.

[[/folder]]

[[folder: Live Action TV ]]

* In ''Series/{{Helix}},'' this is {{Justified| Trope}} in-universe. ResearchInc Arctic Biosystems has lab rats that have been [[DesignerBabies genetically engineered]] to have no sex organs, which perplexes veterinary pathologist Doreen when she examines one and can't tell if it's male or female.

[[/folder]]

[[folder: Literature ]]

* This trope is invoked in-character in ''Discworld/ThiefOfTime'', when Susan takes a paper tube away from Jason and informs the boy that, no, the cardboard animal which the class is constructing is a ''polite'' horse.
** Possibly a reference to a 19th century joke campaign to clothe animals: "A nude horse is a rude horse." was their slogan.
** Also from Literature/{{Discworld}}, the illustrations in ''Discworld/TheWorldOfPoo'' include rear views of Widdler the dog and of a rabbit. Both avert this trope by including a visible dot for an anus, which is only to be expected in a book all about [[NobodyPoops what comes]] [[AvertedTrope out of one]].
* Very explicitly averted in ''Literature/{{Neuropath}}'' when Tom's dog rolls over and exposes his genitals. Agent Gerard find it hilarious and says it's so big it should get its own website. Then makes up some domain names. ("www.dog-got-a-bone.com")

[[/folder]]

[[folder: Myths & Religion ]]

* Japanese statues of the [[http://en.wikipedia.org/wiki/Tanuki tanuki]] feature the animal with large testicles but a very small or completely lacking penis.

[[/folder]]

[[folder: Newspaper Comics ]]

* ZigZagged in ''FootrotFlats''. The trope applies to most of the animal characters, except for Cecil the sheep, who has [[TruthInTelevision very prominent testicles]]. Jess the dog and Dolores the sow also have mammaries when nursing.

[[/folder]]

[[folder: Other ]]

* The mammary side of this trope is interestingly averted with the animatronic goats on the ''PiratesOfTheCaribbean'' ride at [[DisneyThemeParks Disneyland Park at the Disneyland Resort]]; this is a very rare case of goats being designed with udders.
* Most toy animals, especially if they're aimed at younger children, lack gender specific anatomy. This is particularly true of toy horses such as the I Love Ponies range.
** However, models/toys aimed at older children/collectors often subvert this trope. Whilst model horse brands such as Breyer, Bullyland and Schleich played this trope fairly straight in the past, often depriving their stallion models of appropriate anatomy, most newer models, especially since the start of the 21st century, use sculpture models that are completely intact, even adding teats for the mares in the case of Schleich.
* Small pet rodents in films or television are virtually always played by females, even if the animal is male in-story. This is because male hamsters, rats, and mice have ''very'' large testes that would be virtually impossible to hide.
* In heraldry, male mammals are [[AvertedTrope normally depicted with a penis]] if their legs aren't in the way. If the penis is intentionally omitted, the animal is described as "''éviré''".
* For some reason, this trope is commonly averted on ''Website/{{Deviantart}},'' though the attributes are not necessarily in their [[http://tvtropes.org/pmwiki/pmwiki.php/Main/NonMammalMammaries proper places]].

[[/folder]]

[[folder: Pinball ]]

* ''Pinball/PoliceForce'', set in a WorldOfFunnyAnimals, plays this straight for the most part, as even the animals without pants have no attributes visible.
** Subverted with a tortoise around the bumpers, whose clenched anus can ben seen beneath his shell. It's not normally visible from the player's position at the end of the table, however.

[[/folder]]

[[folder: Video Games ]]

* Some dog lover found the Dog's lack of attributes so annoying in ''VideoGame/DragonAgeOrigins'' that he made a mod that put a modest sheath between his legs... and was promptly accused of interest for bestiality by the community members. This trope is ''strong'' in people's minds.
* The fact that Franchise/{{Pokemon}} lack visible attributes (with exception for Miltank's cow udders, of course) is likely a culmination of its simple visual art style and kid-friendly target audience (and GRatedSex). The actual {{Mons}} can probably be assumed to still possess their attributes...after all, that Berry fertilizer (made in part from their "[[NobodyPoops well, you know...]]") has to come from ''somewhere''....
** Various Pokémon draw their designs from things other than animals, so whether their attributes could even be identifiable as such varies as much as the Mons themselves. How exactly does one tell the difference between, say, a male and female Grimer -- ''living blobs of toxic goo?'' Eh, [[BellisariosMaxim forget we even asked]].
*** '''Can''' one tell between male and female "living blobs of toxic goo"?
*** [[FridgeBrilliance From the sexual chromosomes in their DNA, maybe?]]
** Bidoof might be an aversion. The male has [[GettingCrapPastTheRadar two extra bumps]] on the underside of his tail.
* Partial aversion in ''VideoGame/FinalFantasyXII''--no monster has genitalia (or anything we would recognize as it), but a few do seem to have anuses--especially the wolf monsters.
** The wolves in FFXII actually do have female genitalia. Interestingly enough, the giant wolves have a different texture from the regular, and they're noticeably in heat.
* ''VideoGame/KnightsOfTheRound'' has the Mad Tiger enemy, which when knocked into the air is revealed to have a sizeable pair of balls.
* Mostly played straight: The other animals in the realistically rendered video game, ''VideoGame/RedDeadRedemption'' don't have any genitals or other "attributes," but the cattle, sheep, and horses do (if you look very closely in the sheeps' and horses' case). Also, the cows are shown with udders.
* Partial aversion in Tales of Vesperia. Repede has a visible sheath, but no testes, and other dogs, as well as the monsters, are noticabley lacking in the downstairs attributes.
* None of the animals in ''VideoGame/AnimalCrossing'' have genitals, despite [[HalfDressedCartoonAnimal most being pantless]].
* Zig-zagged in ''A Dog's Life''. Jake has a noticeable sheath in the intro animation but in the game itself he's bare.
* Amaterasu, the main character of {{Okami}}, has a spot under her tail that appears to be an anus, averting this trope. However, it gets zigzagged, as she doesn't have any sort of indicator of gender (no vagina or nipples).
* Mr. Tibbs, a cat with a minor role in ''TheLostCrown'', walks with his tail held high in a few scenes where his lack of an anus is apparent.
* Animals in ''ZooTycoon 2'' poop regularly, and some even squat or lift their tails to do so. Most (except for hippos) have no sign of an orifice for them to poop with, however.
** In the "Extinct Animals" expansion pack, aurochs cows have visible udders, but no teats.
* In ''VideoGame/GrandTheftAutoV'': Averted with the dogs as they show a penis sheath and the cows because they have udders. The cattle and dogs have an anus. The other animals don't show any genitalia, anuses, other attributes.

[[/folder]]

[[folder: Western Animation ]]

* Pretty much any time you see an animated animal belonging to a species that would have external genitalia in RealLife, even [[NearlyNormalAnimal when]] [[SpeechImpairedAnimal they're]] [[TalkingAnimal not]] [[PartiallyCivilizedAnimal anthropomorphized]].
* In ''WesternAnimation/CodeLyoko'', Odd's dog Kiwi is ''most definitely'' an aversion, as evidenced by the two lumps between his hind legs.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' (Also included in Non-Humans Lack Attributes due to civilisation of ponies) attention is constantly inadvertently drawn to their lack of attributes by perpetually raised tails and frequent use of from-behind perspectives.
** The episode "The Best Night Ever" played with this trope. When Spike wants to be let into Rarity's boutique while the ponies are getting ready for the Grand Galloping Gala, she objects by stating they're "getting dressed", to which Applejack immediately points out that they normally don't wear clothes anyway.
** In the episode "The Super Speedy Cider Squeezy 6000", Rainbow Dash wakes up Fluttershy early so that they aren't too late to get cider. Rainbow Dash pulls down the covers she's holding up over her, causing her to blush and cover her chest with her forelegs, even though she has no visible genitals or mammaries (which would all be at the other end of her torso) (and they're all almost always nude anyway).
* While generally played straight in ''SamuraiJack'', one scene in the final episode required Jack to find milk for a lost baby boy, leading to a few depictions of female animals with visible udders, although his attempts to milk the wild animals were not entirely successful.
* ZigZagged with the miniature horses in one episode of ''WesternAnimation/TheOblongs''. The horses lack genitals, but they have anuses that look like the letter "x".
** Averted with the dog Scottie, who has both a visible anus and sheath. No testicles are shown, but since he's a dog, he could just be neutered.
* The genital side of this trope is averted with the horses in ''WesternAnimation/KingOfTheHill''.
* Averted with ''WesternAnimation/AlmostNakedAnimals.'' The ''duck'' (among others) has nipples.
