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

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. They both wear black. At Grillbys Dogamy and Dogaressa are beside each other.

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.
