Annoying Dog

The Annoying Dog is a returning character from Undertale. The dog represents Deltarune's creator, Toby Fox.
== Profile ==
=== Appearance ===
The Annoying Dog is a small white dog, looking similar to the miniature Cloud Spitz breed. He often sports a smiling face. The dog's appearance is unchanged compared to the Undertale counterpart.
== Main Story ==
=== Chapter 1 ===
When Kris looks through the window of the Library's Computer Lab, they can see the Annoying Dog working on a game. The narration states, "(Seems like when the game's finished, you can go in...) (You just have to trust the dog...)" If Kris peers through the window a second time, the dog is "playing the maracas" and not doing any work.
=== Chapter 2 ===
Undyne informs Kris that a "little dog" in a toy car appeared while she was directing traffic. With the car, the dog did "donuts" in the middle of the street. This caused assorted cars to be piled around the Library, blocking the road. If Kris interacts with Scared Donut Guy, he explains his disappointment. He had "sped over" when he heard a dog was doing "donuts," expecting food, not a "special attack for cars."
 In Cyber City, when Kris is in the west alley of the road with yellow cars, there are yellow signs of a dog. If Kris passes the signs, they are transported alone to a path that leads east. Further down the path, the Annoying Dog appears in a toy car and rams into Kris's SOUL, depleting their HP. When they are downed, the Undertale Game Over screen appears. The Annoying Dog immediately drives into the words with the toy car and squishes them. Afterwards, Kris respawns at the Dog Dumpster with a Dog Dollar in their inventory. The dumpster also has a pillow for the dog to sleep on. This does not happen on the Snowgrave Route.
As Kris drives Queen and Noelle in a car, they had to stop due to a traffic jam. Queen comments that "A Dog Must Have Wandered In The Road Again."
In Queen's Mansion, Queen hid a key under one of 48 platters in the dining hall. Kris notices a moving platter with small white limbs underneath it. Upon interaction, Kris, Susie, and Ralsei surround the table. The Annoying Dog reacts with surprise and backs away, and the platter falls off. After Susie attempts to threaten the dog, he runs across the room with the party atop the table. Once the key is found, the Annoying Dog breaks it, then charges and explodes the locked door. The dog charges through the hallway with the party atop the table until he hits a wall. The party jumps off, and the Annoying Dog flees to the right. In the introduction of the Giga Queen fight, the Annoying Dog can appear among the rising boulders.
=== Dogcheck ===
Altering save file data to certain inaccessible or nonexistent rooms (such as room 5), like in Undertale, can result in the Annoying Dog appearing upon game launch, and the window title changing to "DOGTARUNE." This is referred to as a "Dogcheck," named by the internal procedure for checking for that illogical state. If a dogcheck is triggered in Chapter 1, the dog is just seen sleeping. In Chapter 2, however, he drives his car across the screen and occasionally more (smaller) cars at varying speeds also appear (driven by smaller Annoying Dogs).
These screens can also be brought up by loading a save file made in the 2021 version of the game through the SURVEY_PROGRAM version.
Dogchecks could also occur if the save file is massively corrupted (such as most of flags are empty and not nulls).
There are several hidden music tracks associated with the various forms of Dogcheck.
 On deltarune.com, the 404 Not Found error page displays either a sleeping or maracas-playing dog, and is likewise titled "room_dogcheck." Clicking the dog can plays one of the two unique songs: Results, or Baci_perugina2. The page itself is similar to the countdown during the UNDERTALE 6th Anniversary stream. Additionally during the stream, the Annoying Dog makes an appearance on the balcony of Sans's House, shaking maracas.

== Trivia ==
* In the Power Stats menu, Kris's first "???" slot can randomly change to "Dog:," with the Annoying Dog sleeping beside the text.
** In Chapter 1, Ralsei's Kindness slot can also randomly change to "Dogness: 1." 
* In Chapter 2, as Susie pulls Ralsei into the north alley, three cones with the Annoying Dog's face block the path.
** When Kris checks one, it plays a barking sound used during Undertale's Lesser Dog battle. If interacted with multiple times, the pitch of each bark can vary.
* When the Annoying Dog rams into Kris with the toy car, the death is scripted to occur. Using debug mode to increase Kris's HP does not change the effect.
* In Queen's Mansion, the dog can still be moved as he runs down the hallway to hit Swatchlings or other platters.
* The DELTARUNE Chapter 1 Spoiler-Free Trailer contained many Annoying Dogs as censors.
* Toby teased the Annoying Dog on a toy car in a tweet 2 years before Chapter 2 released.
** In the same tweet, he also foreshadowed that the Annoying Dog would run Kris over with the car, thus being "the last thing you see before you die"
** The car appears to be a Little Tikes Cozy Coupe drivable toy car.
** The Annoying Dog in a toy car also makes a cameo appearance in the UNDERTALE Xbox One Announce Trailer, during Undertale's Bratty and Catty's dialogue. Incidentally, the trailer's upload date was March 15, 2021, and Deltarune Chapters 1&2 was released on September 23, 2021.
* The sprite of the Annoying Dog playing a piano first appeared at the end of the UNDERTALE 5th Anniversary Concert, as Toby Fox played piano-only variants of My Castle Town, Undertale's Snowdin Town, and Home (Soundtrack). The sprite later appeared in the DELTARUNE Status Update Sept 2022.
* During the Spamton Sweepstakes 2022 charity event, the Annoying Dog appears on a page that was added to the official Deltarune website. It is deltarune.com/dog/, which upon clicking the frame, depicts the Annoying Dog in the frame and the words "BEST INU" underneath. The song dog plays in the background. The frame itself resembles a sepia variant of the frame used in the Playstation 4/Vita version of Undertale's Dog Shrine.
* Annoying Dog is one of a few returning characters from Undertale to have been seen or depicted in both the Light World and the Dark World. This trait is shared with Everyman and ICE-E.
