Talk show host, Dr. Phil McGraw, is fighting back at allegations by a former best friend who claims she was severely bitten by McGraw’s beloved family dog.

In the court documents, obtained exclusively by Breaking Celebrity News, Dr. Phil’s attorneys are demanding that the lawsuit be dismissed because it’s in violation of an agreement to arbitrate any disputes.

EXCLUSIVE DOCUMENTS: Dr. Phil request lawsuit be dismissed.

Breaking Celebrity News broke the exclusive story about the lawsuit pitting former best friends against each other.

According to the response filed March 7, Dr. Phil’s attorneys state that the alleged victim, Janet Harris allegedly signed an arbitration agreement in 2009 that stated in part: “I Janet Harris agree that any and all disputes, now existing or hereafter arising, between me…and Dr. Phillip McGraw and/or Robin McGraw… will be resolved exclusively and solely in a binding, confidential, private arbitration….”

The McGraws are seeking an order to dismiss Harris’ lawsuit and settle the lawsuit in arbitration.

Harris was frequently featured on the Dr. Phil’s talk show as a skin care specialist and became a close confidant of the McGraws. Her lawsuit contends that she traveled with the McGraws for business and pleasure, spent holidays with them and more.

But all of that changed when Harris visited the McGraw's Beverly Hills home in late 2009 and Maggie, their Korean Jindo, allegedly attacked Harris "without provocation and warning," according to the complaint filed February 2 by Harris' personal injury lawyer, Larry Nagelberg.
