Dogamyressa

Dogamyressa is the het ship between Dogamy and Dogaressa from the Undertale fandom.

Canon
Long before the events of the main game, Dogamy and Dogaressa placed second in the Nose Nuzzle Championship '98, placing only behind Asgore and Toriel. Some time later, the two joined the Canine Unit of the Royal Guard. A sign says there is dog marriage right before you meet them. Dogamy and Dogaressa kissed and it showed a heart. At Grillbys Dogamy and Dogaressa are beside each other.

If Frisk plans on sparing the dogs, they roll in the ground and trick the couple into thinking they're a lost puppy. They then pet both of the dogs, leaving them to think that dogs can pet other dogs.

It is impossible to spare exactly one of them. If Dogaressa is killed first, Dogamy's attacks become weaker as he feels sadness over his wife's death. If Dogamy is killed first, Dogaressa's attacks get stronger, as she gets angry and tries to avenge her husband.

In the True Pacifist ending, the two reunite with their long-gone parents, all four of whom, along with other dogs, have merged into an Amalgamate called Endogeny.

Fanon
Most fans ship Dogamy and Dogaressa due to them always appearing together and undoubtedly being in love with each other. It does not have any notable rival ships.
