Dik-diks live in pairs, not herds.

Most antelope live in herds, because there's strength in numbers. Not so with dik-diks. Once they find that special someone, they spend the rest of their days as a couple—usually about four years in the wild. Dik-diks mate for life. They kick their offspring out of the territory when they reach adult size at seven months old, which usually coincides with mom's next pregnancy. Mothers run off female offspring, and fathers run off sons.
