LOST: Old English Sheepdog

Our sweet girl, Martha, got out of our backyard in Prescott Valley Saturday while we were in a conference in Phoenix. Martha is an OLD ENGLISH SHEEP DOG. No doubt, she escaped looking for us, and it breaks my heart that her collar was left behind. She was probably roaming the Buckboard/Roundup/Horseshoe neighborhood sometime after 1pm Saturda April 12th. Her hair is getting a little shaggy. . . now, she's got about 6 mos. worth of growth(the picture is a little old) and she may or may not have her top ponytail in, so her bangs will look long. She has no tail. When she's happy, her WHOLE rear end wiggles. :) Her feet are trimmed up to her ankles. Over all her colors are black (my hubby says "dark gray")and white. PLEASE give us a call if you've seen her, even if it was a few days ago or off in the distance. She's a big girl, about 75 lbs. She stands right around my knee/thigh. Some people call her "shaggy dog" or "disney dog" when they see her, so hopefully she's caught some attention. Please, please, please email or call 928-777-8947. My three-year-old son is calling for her everyday. She and I (especially) had a very deep, loving connection, and I'm really hurting. PLEASE keep your eyes open for her and talk with neighbors and other people you know. I would think she'd be hard to miss, but we're just not connecting with anyone who's seen her. Thank you all so much for your kindness.
