Undertale Wiki

Lesser Dog is a miniboss the protagonist encounters in Snowdin Forest. It is later found as an NPC in Grillby's. It is a member of the Royal Guard.



Lesser Dog's fur is a light cream color, and its red tongue appears to be perpetually lolling out of its mouth. It wears gray, presumably metal armor with a darker gray band around the waist area. It holds a sword and a shield with the Delta Rune.

Like several other dog characters, Lesser Dog becomes overexcited from physical attention. It is capable of extending its neck at a seemingly limitless rate when stimulated by being pet.

Lesser Dog appears to enjoy spending its time off sentry duty by playing card games (namely, poker and go fish) against itself at Grillby's. When interacting with it at this time, the text mentions how it appears to be losing.

Main Story

Neutral Route

While waiting around its sentry post in Snowdin Forest, Lesser Dog spends a lot of its time making snowdogs, mostly with necks in similar lengths to its own. A faun monster standing near the post notes that it seems to get overexcited in the construction of the figures and never finishes them. It may be that Lesser Dog is able to achieve focus by being pet, as after being pet by the protagonist its statues become more complete. The more pets it receives, the more statues Lesser Dog creates around its sentry post, until they all become broken statues of its very long neck when it is pet enough times or has the Stick thrown at it. In this case, the faun states that a dog came by full of excitement and started building sculptures, but its neck kept growing and it kept adding snow to the sculptures until they broke. On the flip side, if Lesser Dog is killed, its sentry post is accompanied only by a pile of formless mushy snow.

True Pacifist Route

In the playable epilogue for the True Pacifist Route, Lesser Dog has, apparently, finally won a game of poker against itself, sitting in Grillby's bar - the only dog character not to be outside the Snowdin Library playing with its family member(s) Endogeny. In the True Pacifist Ending Credits, it can be seen building sand dogs on the beach.

In Battle


  • A dog resembling the Annoying Dog appears to the right of the screen and runs on the spot for a moment before leaping to where the protagonist's SOUL is. If the dog did not jump far, it is possible for the dog to start to jump again as the attack ends.
  • A blue spear comes in from the right of the screen and moves all the way to the left, followed by a white spear coming in from either the right or the left, stopping in the middle, and moving back for a moment before the attack ends.
  • Lesser Dog stops attacking once pet six times ("Critical pet!").


Lesser Dog upon being pet enough times

It is very easy to spare Lesser Dog.

  • Lesser Dog can be spared simply by petting it only once. If Lesser Dog is pet more times, its head keeps rising, eventually ceasing its attacks, surpass the dialogue box, and even the menu. Lesser Dog can be pet 54 times before petting it triggers no new messages.
  • Like other dog enemies, the Stick can be used to instantly make Lesser Dog spareable.

Lesser Dog's sculptures after it has been pet more than twice.

  • Lesser Dog's name derives from the constellation Canis Minor, which is Latin for "lesser dog."
  • Lesser Dog has a weapon called a dogger, as mentioned in the CHECK text, which is a pun on the word "dagger."
    • The "dogger" is made out of "pomer-granite", a pun on Pomeranian, a dog breed, and granite, a kind of rock. This is also possibly a pun on the fruit pomegranate.
  • The Red Bird NPC in Grillby's comments on the disappearance of the Dogs, even if Lesser Dog is still alive.
  • Interestingly, Lesser Dog is never mentioned by the other guard dogs. Killing it provokes no reaction from the other dogs at Grillby's. In turn, if Lesser Dog is the only guard dog left, how it acts at Grillby's does not change.
  • If Lesser Dog is the only Royal Guard member the protagonist has killed, Undyne comments on it, claiming that it was only seeking affection.
  • Lesser Dog is usually the third monster the protagonist encounters in Snowdin Forest (the first two being Snowdrake, then Ice Cap). However, when Lesser Dog is encountered is completely random, like other monster encounters. It is always killed on a Genocide Route, though it is possible to move through Snowdin on a Neutral or True Pacifist Route without encountering it.
    • However, if the protagonist never encounters Lesser Dog on the Genocide Route before facing The Gauntlet of Deadly Terror, Lesser Dog is seen building a snowdog. Also, the protagonist can find Lesser Dog at Grillby's.[2]
  • Lesser Dog's guard post contains a box of pomeraisins, and its weapon is made of pomer-granite. The joke here is a reference to the breed of dogs known as Pomeranian.
  • Lesser Dog is mentioned by the River Person as they say: "Pet pet pet... The neck stretches infinitely into the cosmos. ...Don't worry about it." This is also a reference to the easter egg that can be achieved by petting it at least 54 times.
  • Lesser Dog is the only Royal Guard member that is not a boss or miniboss.
  • Despite being called Lesser Dog, compared to Greater Dog, Lesser Dog is bigger, if you do not count their armor.
