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.
