Help Find Pearl: 8 Mo. Blue Heeler Missing

Pearl is 8 Mos. Blue Heeler/ Australian Cattle dog. Mostly black torso with spotted white underside. Distinctive marking like a window on her butt. Spots on her leg start out black on top and turn tan toward feet. She's curious, affectionate, playful. Reward or another Heeler. An old friend's dog birthed her, and he gifted her to us because my daughter used to have a Heeler before she passed. Please help bring Pearl home.
