Plural of hog; domestic pigs, especially those raised for meat production.
From Middle English 'hogge', possibly from Celtic origins. The word originally referred to a young sheep before being applied to swine in the 14th century. The shift in meaning may have occurred due to similar husbandry practices.
Pigs are incredibly intelligent animals, ranking fourth in animal intelligence after humans, apes, and dolphins. The phrase 'pig-headed' is ironically unfair since pigs can learn their names, solve puzzles, and even play video games using joysticks!
