Judge Judy fight spills out of "court"

The loser in a recently-taped episode of Judge Judy is harassing the winner, according to a restraining order filed in Los Angeles—all over a dog.

The two squared off on an episode of "Judy" that was taped May 23 -- after Gardenhire claimed Whitman owed her money for taking care of an Ace of Hearts dog while the org. searched for a permanent owner. Judy ruled for Ace of Hearts ... but after the show, Whitman claims Gardenhire began a campaign of harassment ... and even made violent threats. According to legal docs obtained by TMZ, Whitman claims Gardenhire warned her, "Watch your back bitch" and threatened to steal Whitman's dogs in retaliation.
