Help, my puppy escaped! Federal and Bryant

UPDATE - PUPPY FOUND AND OK! Someone shoved her in their yard and posted on fb. My buddy and the Rover folk picked her up. Goblin is safe and sound. Hey Denver! Please help, my puppy dashed out the door at the dog sitter. I'm currently getting a flight home. Her name is Goblin, and she's a Blue Heeler/Australian Cattle Dog puppy, 4 months old. 49th and Bryant St. She is fast but really sweet. Knows her name, shy but friendly with other dogs. I'll give a $200 reward if she's found safe.
