HELP! MY DOG IS LOST

Hey everyone, I'm in desperate need of help. My baby Winter is lost. Someone opened my gate and she ran or maybe someone took her. She is a pocket bully, she's very sweet. I've been searching for 3 hours and I haven't found her. My home is near Moross and Rolendale, very near to St John Hospital. I'm so scared for her. It's cold and dark now and I don't know what to do to find her. We got her like 3 months ago and she's kinda carefree and will run. If anyone sees her please get her and contact me. She's such a sweet dog. I know I'm rambling but I'm beside myself knowing she out there somewhere. Please help me. I don't have a car so I've been walking around searching.
