While the rest of Whitney Chiong's pigs are content to romp and chomp outside, Calvin prefers the cozier confines of the house.
"The other pigs want no part in being house pigs anymore," Chiong tells The Dodo. "They have all this land to root up and explore.
"Calvin is a super couch potato, spoiled rotten, super cuddly guy."
And that suits Rizzo perfectly. The pig-obsessed puppy had been trying seemingly all his life to get his porcine siblings to play with him.
