• Females have six nipples; young are born underdeveloped and remain in the pouch for a prolonged period.

Müller’s three-striped dasyures typically live for four years, although the maximum recorded lifespan is seven years; the species reaches sexual maturity between eight months and one year and one month. The young spend the first few months in their mother's pouch, where they feed on milk and grow for a duration of one to four months. During this “young” stage, the animal develops; afterward, it enters the “adult” stage, lasting from four months to five years, at which point the species is capable of hunting and reproducing.
