The female gives birth to one offspring.

An excerpt from the article 14 facts about dik-dik

The male reaches sexual maturity at twelve months, and the female at six. A female can become pregnant twice a year (at the beginning and end of the rainy season), with gestation lasting for up to six months.
Unlike other ruminants, a young dik-dik is born head first rather than with its front legs.
Due to their size, the typical survival rate of a youngster is about 50%. For some time after birth, the young remain in hiding, but after reaching full size in seven months, young dik-diks are run off from their parents’ territory—males by fathers and females by mothers.
