Ivan is an animal character in Halloween II (2009).
Ivan was the pet of the Benny family. He was brought along with Sherman Benny, his wife and Floyd when they went to chase Michael Myers off their land. They kept Ivan locked in a cage on the back of their truck as he was most likely too aggressive to be let out. Michael murdered his three owners and Ivan was left to fend for himself. The dog barked at Michael, who displayed no fear and slew the animal. Michael then ate the dog's remains.
