Missing Animal - Dog

My niece at, 600 block Coolair, was pet sitting for me yesterday,March 18, when my dog got away, about 3:30 p.m. She has no collar on, almost completely tan with an almost completely black tongue. Short-haired, 60ish pounds, spayed, perky stand-up ears, and her tail sticks up and rotates like a helicopter blade when she is happy. Thank you, Suzanne 214-388-8482
