Dog whispers Cesar Milan may have to learn some new-softly spoken commands.

A new lawsuit alleges Milan's pitbull Junior mauled one of Queen Latifah's to death during her visit to his Dog Psychology Center in Santa Clarita, California in 2017.  Milan then made it worse by instructing his staff to tell Latifah her pooch had been hit by a car.

Latifah isn't the one suing Milan.  Instead, her sad story is being used as evidence in a suit filed by  Lidia Matiss, who had her leg bitten by Junior.  Matiss had been a top-rated gymnast who was being recruited by colleges.  Matiss claims her dog-bite injuries ended her athletic career and cost her a scholarship.

Milan's lawyers are arguing Matiss assumed the risk of being bitten and therefore Cesar isn't liable.

Junior died earlier this summer at age 15.
