CHICAGO — A new law in Illinois will put fido center-stage in custody battles.

Beginning Jan. 1, divorcing couples who can’t agree on pet custody will have to prove to a judge who’s the better owner.

Animal rights attorneys say the judge will weigh who does the day to day care taking of the pet, like feeding, walks, and vaccinations.

Earlier this year, Alaska became the first state in the nation with this type of law.
