Duck Hunt Dog

Dog, also known as the Laughing Dog, is a character from the NES video game, Duck Hunt. As his name suggests, he is a dog. In Super Smash Bros. for Nintendo 3DS/Wii U, he becomes a playable character in the game who tags along with a duck from Duck Hunt.

He is an infamous character. The dog has become a sort of icon of the game due to him laughing at the player whenever they fail to shoot a duck, and his popularity has even got him mentioned on TV.

Why He's Not "Man's Best Friend"

 * 1) Because of him infamously laughing at the player for every miss they make for shooting a duck, it has been carried to the point that he's considered to be one of the most annoying video game characters alongside Navi the Fairy, Thief Pig, Omochao, and the list goes on.
 * 2) He is a widely hated videogame character because of his role in Duck Hunt as a sidekick who was meant to be the player's hunting companion who drives the ducks out of their hiding spots and collects the dead ones for you. Normally, you expect the dog to be disappointed or sad since its efforts were all for naught (and thus make you feel guilty). But instead, it laughs at you for missing, and given that each round has the ducks fly faster and more sporadic, you will experience this moment eventually.
 * 3) He is well known for having an annoying laugh that is played every time the player fails to shoot the ducks. While the sound itself isn't that bad to hear the first time, this becomes rather annoying to hear the same sound clip on repeat.
 * 4) * This led many players wanting to shoot the dog for being a poor sport, and some even believe the dog was never on your side, instead of conspiring with the ducks to make your life miserable. This is carried to the point that you even want to shoot him when you see him laughing.
 * 5) * Some die-hard Nintendo fans found his laugh terrifying when they were young.
 * 6) Due to him not speaking, he does not have a clear personality.
 * 7) If you don't shoot any ducks with your 3 bullets, he will laugh at your failure, proving he loves mocking pretty much anyone.
 * 8) Him laughing at you every time you can't shoot a duck shows that he practically bullies you when playing Duck Hunt.
 * 9) He hardly gets any comeuppance/karma for his actions, making him a Karma Houdini.
 * 10) Where he did appear in the Smash games, for some reason, he became friends with Duck. Which seems odd since he was always enemies to them.
 * 11) * Also, his friendship with Duck in the Smash games was rather vague and unexplained, this is better shown when they hardly even interact with each other.
 * 12) While in-game he looks appealing, he has had instances of having an ugly character design, like this one for example.
 * 13) * His extremely uncanny 3d design in the infamous "You Cannot Beat Us" Nintendo Entertainment System commercial in 1986 (View the image at your own risk). He also had a very disturbing  voice as well to match the creepiness of this version of Dog's design.

Redeeming Qualities

 * 1) Minor nitpicks aside, he has significantly improved as a character in the Smash games.
 * 2) He can be also quite fun to play as him in the Smash series, depending on your view.
 * 3) * His snicker was done decently (and in a way anyone can enjoy listening to), which sounds better than his laugh on the NES.
 * 4) He has a good character design.
 * 5) Since you are able to shoot him in VS. arcade version of Duck Hunt, this means the player can get back at Dog for laughing at you remorselessly. Sure, you're penalized for shooting him by getting an earful from him and being taken out of the bonus stage, but nonetheless, it still feels satisfying.
 * 6) * This pointer aside, he actually has been given comeuppance by Banjo himself for his infamous laughing that was played for comedy in the reveal trailer for Banjo Kazooie, where Dog is rather funny & entertaining to watch. His comeuppance is hilarious to see coming from Nintendo themselves.

Reception

 * Dog has received a mixed reception from people, despite getting more negative reception than positive reception.

Trivia

 * He is a Labrador Retriever. Bred for marking, retrieving, and delivering waterfowl directly to your hands.
 * He got his own page on Wikipedia because of how infamous he is.
 * Despite the fact that you can shoot the dog in the VS. arcade version of Duck Hunt, unofficial titles have been released on the internet where the dog can be shot. These are typically more graphical and often result in the dog dying rather than just a face full of gunpowder like in the Vs. Series version.
 * The dog laughing at you has been mocked and parodied time and again all over the internet. It is infamous and became an ascended meme when the trailer for Banjo & Kazooie being added to Super Smash Bros. Ultimate dropped, with the duo being impersonated at first by Duck Hunt, who proceed to heckle the cast of Donkey Kong Country (and the video's audience) with vast quantities of their laughter.
 * Before and after he became an added character to the Smash series, he has made guest appearances in other video games like World Class Track Meet, Barker Bill's Trick Shooting, WarioWare, Inc.: Mega Microgame$!, WarioWare, Inc.: Mega Party Game$, Tetris DS, WarioWare D.I.Y. Showcase, Super Mario Maker, and WarioWare Gold.
 * The snicker he was given in Smash Ultimate/U was never credited.
