Miley Cyrus just got dragged into a lawsuit involving her sister, her sister’s dog and an L.A. model — who claims the pooch viciously attacked her and ruined her career. According to the court docs … Yolande Ngom was bitten by Brandi Cyrus ‘ dog “Feather” in the apartment building where she and Miley’s older sister both live. Miley’s company Smiley Miley, Inc owns Brandi’s apartment — and Yolande says one of Miley’s employees was handling the dog and couldn’t keep it under control … allowing the attack to go down. Ngom says the unprovoked bite ripped open her right thigh … leaving scars so bad she’ll never be able to work as a model again. She’s suing Brandi and Miley’s company for medical bills, lost wages and more.
