With all the drama that goes down on his show, Dr. Phil McGraw knows as well as anyone it's a dog-eat-dog world.

And now it seems Dr. Phil's own dog has gotten the TV personality in some trouble. RadarOnline.com reports that the Oprah-made self-help guru and his wife Robin McGraw are being sued for personal injuries and damages after their dog allegedly attacked and injured their former best friend.

Janet Harris has filed suit against the McGraws in Santa Monica, Calif., claiming the couple's gross negligence resulted in serious injuries. According to court documents obtained by RadarOnline.com, Harris was brutally mauled by the McGraws' dog Maggie without provocation or warning.

The lawsuit claims that the dog bite caused uncontrollable bleeding from deep puncture wounds, as well as cuts and abrasions inflicted on her arm and hand. Harris' lawyers said that "complications from the dog bite injuries forced Janet to seek emergency medical treatment and required extended home nursing care to recover from an incapacitating infection called pasteurella multocida ... [She] spent seven days attached to an IV as well as being prescribed steroids and antibiotics."
