The pig survived and was in critical condition at a veterinarian's office Friday, said Effingham County Sheriff's Office spokesman David Ehsanipoor.
The owner of the dogs, 23-year-old Benjamin Fullwood, was charged Wednesday with felony cruelty to animals, criminal trespass and obstruction of a law enforcement officer, Ehsanipoor said. A bond hearing was set for Friday, and it wasn't immediately clear if Fullwood had a lawyer.
The pig got out of its owners' yard Wednesday afternoon and wandered into a mobile home park in Springfield, Ehsanipoor said. Residents of the park were trying to get in touch with the animal's owner, when Fullwood unleashed his two pit bulls on the pig and then began stabbing the pig in front of a group of people, including children, Ehsanipoor said.
"This was an unprovoked attack. The pig was posing no threat to anybody," Ehsanipoor said. "It was just brutal."
Fullwood initially lied to deputies, saying he was punching the pig, Ehsanipoor said. But witness accounts, as well as the nature of the pig's wounds, led deputies to determine the pig had been stabbed, he said.
