Dogamy and Dogaressa, collectively referred to as "Dogi", are a pair of minibosses encountered in Snowdin Forest. If spared, they appear later as NPCs in Grillby's. They are members of the Royal Guard.
They are near identical in appearance, both having round snouts, floppy ears, and muscular builds covered by dark hooded robes with the face of their spouse printed on the front. Their main differences in appearance being Dogamy's thick lowered brow, cowlick and pseudo-mustache, and Dogaressa's emphasized eyelashes. In battle, they both wield long battleaxes, with eyes that show features imitating those of their owners.
They primarily use their sense of smell to detect others, but not much else, implying their eyesight is inferior, much like Doggo, who either of them may be biologically related to. Despite this, they love each other dearly, and this is shown in their attacks in battle, using heart-shaped attacks and coordinating their axe strikes to form a heart-shape with the gaps between their blades. If either is killed in battle, the other's shirt is shown to have their spouse's picture on it, proving their love further. Each Dogi reacts differently towards the death of the other, with Dogamy falling into hopelessness and despair, while Dogaressa makes threats in a fit of rage, though both show their resentment toward the protagonist by growling and refusing to be pet.
True Pacifist Route
Their yellow text in the credits of the game list them as being "finally" #1 Nose Nuzzle Champions; the previous number one champions (Toriel and Asgore) presumably being unable to participate in subsequent championships due to their divorce.
In the playable epilogue to the True Pacifist Route, the Dogi appear outside Snowdin library with Doggo, Greater Dog, and Endogeny. The amalgamate is revealed to contain the parents of both of the Dogi, and Dogamy muses on whether this means he is now married to his sister before dismissing it as something dogs often do regardless.
If the protagonist first slays Dogaressa, Dogamy's attacks become weaker; conversely, if the protagonist slays Dogamy, Dogaressa's attacks become stronger.
- Two axes are in the battle range. They rise a little before moving downward, moving in opposite directions. The attack ends with the axes creating a heart shape. To best avoid this attack, the SOUL should stay near the bottom of the Bullet Board and move under the axes when they rise.
- Two dogs are on each side of the battle range, the one the left (Dogamy) barks a ring of eight hearts to the dog on the right (Dogaressa). Four of the hearts are blue, allowing the SOUL to enter and leave the ring if they do not dodge it.
- If the protagonist slays Dogaressa, the only attack is the barking dogs, but there is only one dog barking on the left (Dogamy), which feebly barks a single heart towards the bottom of the screen. This represents Dogamy's sadness, as he becomes weaker and appears to be upset about Dogaressa's death in his quotes.
- If the protagonist slays Dogamy, the only attack is the two axes going across the battle area, but they rise and drop much more rapidly. This represents Dogaressa's anger, as she becomes stronger and appears to be angry about Dogamy's death in her quotes.
- To spare them, the protagonist must Roll Around in the snow to disguise their scent, making the Dogi think that they are just a lost puppy, make them Re-Sniff the protagonist and then Pet both of them, opening their minds to the idea that dogs can pet other dogs.
- Alternatively using the Stick as an item causes them to play fetch and can result in SPARE as well.
- Killing Dogaressa makes Dogamy lose 30 DF, quickening the kill process. His attack becomes incredibly weak and easier to dodge, as the attack barely travels on the screen.

- Dogaressa is the term used for the wife of a doge, the title used by the rulers of the Renaissance-era Republic of Venice (now part of Italy), which ties into the Dogi's marriage theme. The name Dogamy is a wordplay on the suffix -gamy used to describe different forms of marriage (endogamy, monogamy, etc.) and ties in with the pair's marriage theme and the sign near their area that reads "Warning: Dog Marriage."
- Dogaressa is sometimes referred as "the Dogaressa" in flavor text, implying that Dogaressa could be a title (as mentioned above) rather than her real name.
- Dogaressa is occasionally referred to as a puppy, referring to the human habit of referring to affectionate partners by the similarly infantile baby.
- Dogaressa's speech is always written between parentheses.
- Similarly to the Royal Guards, it is impossible to kill one of the Dogi while sparing the other.
- Unlike those of the other dog characters, the death of Lesser Dog has no effect on their post-encounter dialogue.
- If the Dogi have been killed but Greater Dog is still alive, Doggo comments on their disappearance by saying "Where's the other two? I can't play with this big dumb guy alone... He'll just win!!!".
- If the protagonist kills the Dogi during a Neutral Route, the bear arranging the Christmas presents under the tree in Snowdin tells the protagonist about their present exchange tradition and wonder where they are.
- Before the battle with Undyne, she mentions Dogamy and Dogaressa if they were killed before.
- If the protagonist re-reads the sign near the Dogi's area, the sign changes from "Warning: Dog Marriage" to "(Yes, you read that correctly)". Any sequential reads afterward read the original text.
- If the protagonist reads the sniff sign in front of their house, the green smell is in red letters. This is a reference to dogs being colorblind between green and red.
- If the player uses debug mode to kill one and spare the other, the game continues as if having killed both of them.
- During the True Pacifist Ending Credits their nuzzles move from one side to the other, unlike in their battle.
