The names pig and hog most commonly refer to the domestic pig, (Sus domestica).Domestic Pigs and their closest relatives are even-toed ungulates. Pigs are omnivores, and despite their reputation for gluttony, they are generally social and intelligent animals.

With around 2 billion individuals alive at any time, the domesticated pig is one of the most numerous large mammals on the planet.

The species they were domesticated from is the wild boar. The many subspecies of Boar are native to all but the harshest climes of continental Eurasia and its islands, from Ireland and India to Japan and north to Siberia.

Pigs have evolved into many different species, including wild boars, bearded pigs, and warty pigs. Humans have introduced pigs into Australia, North and South America, either accidentally as escaped domestic pigs which have gone feral, or as wild boar. These have typically adapted well, and are increasing in number and broadening their range outside of human control.

Domesticated pigs are commonly raised as livestock by farmers for meat (called pork), as well as for leather. Their bristly hairs are also used for brushes. Some breeds of pig, such as the Asian pot-bellied pig, are kept as pets.

Pigs that are allowed to forage may be watched by swineherds. Because of their foraging abilities and excellent sense of smell, they are used to find truffles in many European countries.
