An excerpt from the article 14 facts about dik-dik

Mates spend about 64% of their time together. Their monogamous nature can be explained by an evolutionary response to predation. When surrounded by predators, it is safer to stick with one partner than to explore the area in search of others.

Males mark their territory with piles of dung and cover females’ droppings with their own. If the opportunity arises, males, not females, attempt to mate outside pairs.
