Authorities are searching for a 16-year-old Cheyenne girl who ran away from home early this morning.

Devin Brakel says his step-daughter, Kassidy Kunard, ran away from their home in Sun Valley with her dog, Gable, sometime between midnight and 3 a.m.

Brakel says Gable, who is an Australian Shepherd with a merle coat and two different colored eyes, is Kassidy's "achilles heel" and will likely be with her.

Anyone who knows Kassidy's whereabouts is asked to call the Cheyenne Police Department or the Laramie County Sheriff's Department.
