Pigs are a domesticated animal that appear on a minor scale in the How to Train Your Dragon Franchise.
The Domestic Pig (Sus domesticus) is descended from the Wild Boar. It is a mammal with often sparse wiry hair and two weight-bearing or cloven toes. It is popularly characterized by its snout, which extends somewhat out from its face and ends on a flat pad where the two nostrils are located. The snout is somewhat flexible, and vaguely mimics an extremely short elephant's trunk.
The pig's main function in both the Franchise and otherwise is for meat production. As a meat animal, it can be assumed that Dragons eat pigs as well, though it has not been explicitly stated in the Franchise.
In actuality, pigs have also been raised as pets (Example: Pot-Bellied Pigs). There is limited harvest of pig's milk as well. Pigs are sometimes used to sniff out items, most notably the Truffle fungus.
In this collection of short videos, ham appears as the highest medal a Viking could win. It was awarded to Snotlout, just before a Monstrous Nightmare (presumably Hookfang) snags the ham and Snotlout with it and flies away.
In the episode "Alvin and the Outcasts", Mulch has to go search for Bucket when he disappears while leading the villagers to a cave. Mulch is annoyed at always having to search for Bucket, and calls him a "half wit pig".
In the episode "Turn and Burn", Stoick calls Spitelout "pig-headed" twice; fist when talking to Snotlout after arriving at the Edge, and again when Hiccup is trying to talk Stoick into going back to Storehouse Island to help fight off the Singetails.
Live pigs are not seen in the Movie Short, Dawn of the Dragon Racers, but several incidences of large legs of ham are shown in the background. It is possible these are from Wild Boar, but the size and number of them suggest a domestically raised pig.
Comics and Graphic Novels
During Hiccup's opening narration, a man is seen carrying a dead pig.
One panel in the graphic novel, The Serpent's Heir shows a sty of pink wallowing pigs on the island of Nepenthe. Despite the mysterious dragon roars and the tremoring land, the pigs appear unconcerned. This might be a product of the Foreverwing dragon's sedating breath, who are buried under the island.
In November 2017, School of Dragons released the 'truffle pig' as a farm animal the player could add to their farms. When harvested, pigs will 'find' truffles the player can use to complete Farm Jobs or feed to their dragons.
This children's activity book contains eight scenes for the reader to find hidden objects. In the eighth scene, there are various food items around the Great Hall, including two roast pigs.
A minor character appears in this game named Piglegs.
|“||And his name is Skullcrusher, and he is a big dragon, a tracking dragon, and he's part of the Tracker Class. He's a Rumblehorn, which is the name of the species. He's sort of a cross between a truffle pig and a rhino with the coloring of a scarab beetle.||”|

As an Epithet
The use of "pig" in name-calling is seen in a variety of DreamWorks Dragons: The Series episodes. Examples are:
|“||Oh, for the love of... Why am I always looking for Bucket? Hey, yeah, why can't he-- Bucket? It's like trying to keep track of a half-wit pig.||”|
|— Mulch in "Alvin and the Outcasts"|
|“||Obviously! Pig-headed dragon.||”|
|— Snotlout referring to Hookfang in "Defiant One"|
