Samurai Dogs are simply hot dogs sold under the name of the Samurai franchise. There have been both official and unofficial versions. Missile the police dog and Wendy Oldbag are both great fans of Samurai Dogs.

Toward the end of 2016, Larry Butz, looking for a job, started selling somewhat gourd-shaped hot dogs that he called "Gourd Dogs" at the Gourd Lake Public Beach. His then-girlfriend Kiyance told him to change the name to "Samurai Dogs" and dress up as Santa Claus in order to increase their popularity, though the same hot dogs would be used. To help publicize this new idea, and despite the potential legal implications, Butz set up a large inflatable Steel Samurai beside his stall. Butz wasn't much of a technician, though, so in order to inflate it, he used an air tank. However, the valve on the air tank broke, and the setup shot up into the air. The resulting loud noise drew people's attention, and while someone was taking a photo of the lake, the air tank crashed down into the lake as the photo was shot. The photo was sent to newspapers and the air tank mistaken as a lake monster.
Phoenix Wright and Maya Fey later visited the lake to investigate a murder for which Miles Edgeworth was being accused. Butz was not around when the two first found the stall, and Fey begged Wright to buy her a Samurai Dog, excited by the name. Later that day, the pair met Butz at the stall, who admitted that he still has no way of paying Wright for defending him in a murder trial, but instead allowed them to help themselves to as many Samurai Dogs as they wanted, much to Fey's excitement.

Global Studios eventually made "Samurai Dogs" of their own, and by 2019, they were being sold at the Cohdopian Embassy building as part of the Samurai franchise's involvement in a goodwill event between Allebahst and Babahl. Despite being intended to be a gift from the studios for the nations, Wendy Oldbag, who was playing the part of the Pink Princess for a Steel Samurai stage show, helped herself to some of them. The event was cut short due to the murder of Manny Coachen in the office of Colias Palaeno in the Babahlese side of the embassy, as well as the murder of Ka-Shi Nou in the Ambassador's Office of the Allebahstian side. Much later, Miles Edgeworth confronted Ambassador Quercus Alba of Allebahst, whom he believed was the mastermind behind the Cohdopian smuggling ring and the two murders. Alba eventually admitted to Nou's murder, but due to extraterritoriality rights, he had the right to be tried for that murder in his own country, where he had influence over the courts.
Edgeworth and his allies gathered evidence to prove that Alba had killed Coachen. The victim's blood was found inside the pushcart that had originally contained the Samurai Dogs. Later, Oldbag stepped in, completely oblivious to what was going on, and handed Edgeworth a "special" Samurai Dog, so special that it happened to have the Rising Sun of the Japanese flag on it. Edgeworth realized that that this "sun" was, in fact, a single drop of blood, which Edgeworth tied to Alba, proving his presence in the dressing room where Coachen was killed.
In Turnabout Goodbyes, if the player takes police-trained K-9 dog Missile from Dick Gumshoe to the Public Beach, Butz gets excited by the dog and tries to pet it. Missile, on the other hand, turns fierce and eats each and every last Samurai Dog from Butz's stall. As a result, he is left in tears and rounds on Wright and Fey for letting Missile do that.
