A wolfdog has escaped from Howling Timbers Animal Sanctuary and is on the loose in Muskegon, Michigan, officials say.

Howling Timbers Animal Sanctuary owner Brenda Pearson has been ordered to forfeit all of her wolfdogs to the state of Michigan.

The judge heard testimony that animals at Howling Timbers were fed moldy and rotten food, were underweight and had untreated medical issues.

Wolves at Howling Timbers Animal Sanctuary were chewed on by flies and a wolfdog "smelled like rotting flesh" due to an untreated injury.
