A dik-dik is a small antelope in the genus Madoqua that lives in the bushlands of eastern and southern Africa.

Dik-diks stand about 12"–16" (30 - 40 cm) at the shoulder, are 20"–28" in (50 - 70 cm) long, weigh 7 - 16 lb (3 - 6 kg) and can live for up to 10 years. Dik-diks are named for the alarm calls of the females. In addition to the females' alarm call, both the male and female make a shrill, whistling sound. These calls may alert other animals to predators.

Dik-diks are herbivores. Their diet mainly consists of foliage, shoots, fruit and berries, but little or no grass. They receive sufficient amounts of water from their food, making drinking unnecessary. 
Like all even-toed ungulates, they digest their food with the aid of micro-organisms in their four-chambered stomachs.

After initial digestion, the food is repeatedly eructated and rechewed, a process known also as rumination, or 'chewing the cud'. Dik-diks' tapering heads may help them eat the leaves between the spines on the acacia trees, and feed while still keeping their head high to detect predators.
