[Highland Park] missing dog

Hi, I'm sending this for a friend who doesn't have email access at home. Her dog took off today around lunchtime and hasn't been seen since. Her tags have broken off. The dog is a female border collie (mostly black with two big white spots) named Maggie and lives in the 800 block of Sheridan Ave (just up from Stanton). If you have seen her call Mary Beth at 412.661.4925 or 412.512.9639. Thanks in advance. -Chris
